There are two sections to this campground, the older "west resort" and the new "east resort". We stayed in the newer section, all pull throughs, very open, nice views of the hillsides. There are no bath facilities in the new section, but we never use them so it was not a problem for us. Sites are nice and wide, gravel parking and roads, large grassy area's between sites. There is no shade. Each site has a gravel patio area with a table and brand new grill. We were quite happy and comfortable there. The older section of the park has pull-throughs as well as back-in sites and cabins. There are quite a few permanent residents here and some of the sites were looking like they needed a facelift. Other sites were fine. They are dog friendly, with a fenced pet area as well as some large open fields for the dogs to run in. If you are travelling in a large motorhome I would recommend the new section, any site would work, but there are plenty of sites in the older section that would work as well. It was also very quiet here at night. We would definitely stay here again. We camped here in a Motorhome.

We booked two nights in new Western Deluxe Kottages. Casey checked us in and he was pleasant and friendly. He gave us a map and explained directions to our cabin. The store is set up with an internet area, assorted groceries, and local vendor crafts. The cabins are set on a hill with some of them having easier access to unload your car than others. Some of the cabins are very close together so if your sitting at your fireplace and the other people want to sleep your you can hear those people talking as if they were in your bedroom. For some privacy I would pick H29, H35. H4-H8 are set up on a hill very close together. We drove around the whole campground and like others said, not to many trees. The back row closest to the pet area had the most. The sites looked level and they were gravel. The cabin came with a refrigerator, no microwave, no TV but it looked like it had cable hook up. Their was plenty of electrical outlets. We brought the coffee maker. It does come with an outside grill, I would bring tin foil and my own propane if I was going to use it. We ate at the restaurant and the waitresses were friendly and attentive. The food was good and very reasonable. Overall a very nice campground. We camped here in a Campground Cabin.

This is a large, modern campground but the sites are too small and there are no trees. What is a campground without trees? We camped here in a Tent.

What a difference a year makes. First, the good--great water pressure, level sites, a new dog playground area, and a great water slide at the pool. Now, the rest of the story. Twin Grove has declined significantly in the past year. As a matter of fact, the only that that has not declined are the prices, which are going up--way up. The amusement park now charges over $2.00 for most "rides" and as much for the games. I got one scoop of ice cream for $2.00--it was literally one scant scoop and nothing more on top of a cone. The site rates are going up, presumably to pay for the 24 new cabins they put in over the winter. The workers are not terribly friendly as they have been in the past and several of them speak little to no English. The workers in the golf carts might smile when they drive by, but it is hard to tell when they are driving as fast as they can. The pool monitors spend most of their time monitoring their cell phones instead of the pool. The PA Bike Helmet law is not enforced and the previous restriction on motorized bikes has probably been lifted. There apparently is no speed limit anymore. Ownership has changed in the past year and it seems as though they are changing their focus from RVs to rental cabins. What a disappointment. We camped here in a Fifth Wheel.

I thought the park was great. Very clean, good people working there. Our site was level, though not very shaded. Some sites to back up to the woods which are nice. This is a great park for the kids, alot of good activities to do. Pricing was fair on ice cream and food. The only downfall was being charged to swim in there pool. I thought it was wierd to charge to swim a pool. We camped here in a Motorhome.

The sites are rather small with the exception of a few pull thrus. A lot of sites are not level and drop off outside your door. The drinking water is not very good so bring your own. Roads and most sites are gravel which most dog owners don't like. Pool was very cool due to recent rains. Quiet at night. Not many shaded sites. We camped here in a Travel Trailer.

We continue to go to Twin Grove several times a year. Clean and easy to access, the campground presents a great overall appearance. The shower houses and restrooms are immaculate. The staff, for the most part, is friendly. The pool, with a great water slide, is well-maintained. The campground and park lose a point in any review of mine because everything, except the pool, costs money. A dollar a ride sounds cheap but it starts to add up, especially with two kids over the course of several days. The teens working the rides and games were great, especially the young man during the week of 8/4/08, but staff is at a minimum--two kids attending six rides, the arcade, and game stand. I guess prices would be really high if they actually had enough staff so these hard working attendants could work at a decent, less frenetic pace. Finally, this rating loses a point because of the pool monitor on Thursday. The young lady had little interest in enforcing the rules and allowed an annoying family to dominate the water slide by making everyone wait while they played a game repeatedly. Everyone is supposed to have fun, but this family took over. For whatever reason, they continued without so much as a request from the staff to be more polite. The monitor earlier in the week was much better at keeping people in check in a friendly way. We had a great time with a few minor issues. A level site, full and well maintained hookups, a great campstore, and mostly solid staff makes Twin Grove our "Ol' Faithful." We camped here in a Fifth Wheel.

KOA campground. Could use more 50 amp service, but overall nice campground. Nice restaurant and camp store. Ice cream store on site. Nice family campground. Small amusement park on site as well. We camped here in a Travel Trailer.

This park is 50 years young, but looks brand new. The good points include the pool, the excellent restaurant and ice cream shop, and the friendly staff. The bad points were the jammed together sites and the lack of trees, i.e. minimal privacy. We were there during a Civil War Reenactment Weekend and loved the up close and personal view we had in the field next door. We will return next year for the Reenactment (check the web site), but we did find the lack of privacy unnerving. I wish they had left some undergrowth between sites instead of almost clear cutting the woods. We camped here in a Travel Trailer.

Beautiful campground and the restaurant was very good. 10oz ribeye steak cooked to perfection. Prices were so reasonable, we ate their food most of weekend. Rides were ok [extra bonus]. Mostly open sky, but it looks like tent catepillars may have damaged trees. Pool was nice. Very clean camp, nice movie theater, etc. We will return over & over. This was our 1st time here, but the best KOA we've stayed at. We camped here in a Travel Trailer.

We camped here twice in the last 4 weeks. Both times we had a wonderful time. The staff was very helpful and friendly. There were many well coordinated activities for the kids. The bathrooms, sites, and faculties were clean. We will are making plans to return. We camped here in a Travel Trailer.

Our site was in the new section. Like all the KOA campgrounds we have stayed at: everything was very clean. We had Sunday brunch at the restaurant. The only things missing are trees and Wi-Fi. Also, like another reviewer said, the new section needs bathrooms and maybe showers. We camped here in a Motorhome.

A typical overpriced KOA. Except for a tiny area on the fringe there is no shade. The new area is totally barren and without restrooms..looked ugly. The restaurant food was good but expensive. The girl behind the check-in counter gave the impression of not caring if you stayed or left. She tossed the papers on the counter and said "follow the arrow to your site" then walked away to continue drinking her soda with her back to the counter. Didn't set a very good customer service example. The pool looked nice with a water slide and an umbrella shaped water shower in the wading end for little kids. The amusement rides were nothing fancy. Tickets were 75 cents each...carousel-2 tickets, ferris wheel-3 tickets, moon-bounce-2 tickets, tractor pulled train-3 tickets, and a small arcade area where lots and lots of tickets earned from the games played could be traded for very small trinkets. Playground was nice but lacked swings for small children. Okay for overnight or maybe when something is happening on the weekend, but wouldn't go out of my way to stop here again. We camped here in a Motorhome.

The Park is large and has every amenity you can imagine,and then some. Our site was in a new addition slightly removed from the congestion and chaos of the main campground...which was fine with us. However, the new section does need bathrooms and showers. If you are looking to be entertained and spend some money, this is the place for you! My only complaint is lack of internet access at the site. We camped here in a Fifth Wheel.

A great campground! Long, level sites with reasonable space between campers. There is a restaurant on premises. There is a nice pool. The recreation area includes a carousel and other rides for children. There is an excellent fenced dog play area with agility course. Free wifi. We camped here in a Motorhome.

This was our second camping experience and it was wonderful. The campground is nestled in the hills and it is a beautiful view all around. The pool was clean and inviting. They have an arcade, an amusement park, restaurant and a snack shop with very reasonable prices. The camp store was stocked with the basics. Our campsite was level with gravel. We were backed up to the stream which was a source of entertainment for my girls. The bathrooms were extremely clean and had good source of hot water. I also liked the fact that there was an air conditioner in the bathroom that can be turned on or off easily. A good feature when the bathroom is steamed up. The only thing I would add it an escort to our site. The writing on the map they hand you is microscopic so it would have been nice to have an escort. We will definitely be back. We stayed the weekend after fourth of July weekend and apparently they have their own fireworks show. We camped here in a Tent Trailer.

We just returned from our first visit to Twin Grove. We were on the stream in site Q46. We LOVED our site. Level, near bathrooms (never used them) and large. Some sites were close. Most are wide open with no shade. There is a little overflow "ATV" lot next to us. We had a little shade from the trees lining the stream.Most sites are in the open sun. Our children loved playing in the stream. There are little play areas dotting the campground with a large playground near the pool and central office building. The food at the restaurant for the Father's Day Brunch was excellent! The camp store was well stocked to get you out of just about any RV jam. The pool looked great (It rained the weekend we were there so we didn't use it). The rides were fantastic for small children. We enjoyed the crafts and indoor games/movies during the rainy weekend. Everyone was quiet - even the tons of dogs here- and they drove slowly. Staff was kind, polite, and friendly. They even ran rides just for our 3 kids! We would definitely come back if we could get this site again. We camped here in a Travel Trailer.

This is the second time I have been to Twin Grove campground. The first time was pleasant enough, though very bright as many large trees had been cut down. This time I ended up in the "new, deluxe pull-through site" area. This area was not ready for prime time. It was sterile and sun-baked, with the sewer connections up hill at all sites. The restroom/showers were nowhere to be seen with the closest being a 20-minute walk away. Apologies were made and discounts offered after the fact, but it was a very disappointing holiday camping experience. We camped here in a Travel Trailer.

This is a very nice campround, and continues to add more sites now under construction. The pool looks nice, but opens after Memorial Day. The have a small amusement park for an extra fee - nice for the kids but bring money. Restrooms are family type and very clean. They have a sink, toilet and shower in each with plenty of room to change.Perfect AT&T air card reception, and good satellite signals. Pull through sites are very long and very wide. You can pull in without unhooking the towed vehicle. Sites and roads are gravel and very level sites. Tables are extra long. Pavilions available for use at an extra charge. We camped here in a motor home in a nice open space with plenty of room. Price reflects KOA discount. We would camp here again. We camped here in a Motorhome.

Many pull-thru sites, nice green grassy patch at each site. Nice gift shop with a few groceries, and ice cream cones. Very friendly staff. Very pastoral area, quiet and peaceful feeling, even though it is very close to Interstate 81. No Campground area Wi-Fi. Internet available in the office area. Good overnight stopping place. We camped here in a Travel Trailer.

This campground was open all year and was very nice in the winter. The cabin had one room that had a queen bed and a bunk bed and a table and chairs. The owners went in ahead of our visit and turned on heaters so that i was nice and toasty when we arrived. I would like to visit in the summer to use the pool and restaurants. We camped here in a Campground Cabin.

We Camped there for a picnic. Staff were just great and the pool was clean, store small but well stocked with incidentals. Many of the sites were very open. The center pull through have no shade 'cept what you bring with you. Next time I'll try to get a shaded site on the outer edge. We camped here in a Travel Trailer.

This is by far the best KOA I have ever stayed in. My wife and I were there for 32 days and paid the extended stay rate. Everyone was extremely friendly and helpful. I enjoyed the food at the restaurant (except the Taco bar on Wednesday). Seems the Pennsylvania Dutch don't really know what a Taco bar should be like. The toilets, showers and Laundry rooms were the cleanest I have ever come across in a Campground. I highly recommend this park for any one to visit. We camped here in a Motorhome.

While I believe this campground has only recently become a KOA, it has been around for a long time. My in-laws had a brochure from 1971 when rates were $3.50/night. They got a laugh in the office when I complained that the rate was higher then the brochure and showed them my relic. It is important to note that the correct name is Twin Grove Park KOA. Twin Grove Park was originally a local amusement park, and the campground came along later preserving some of the rides and adding newer ones later. The staff was very friendly (and obviously had a good sense of humor) and check-in was speedy. The camp store was well-stocked. The restaurant was adequate. Not 5 start cuisine but good enough if you are looking for a quick meal. We had breakfast there. The pool was nice though with temperatures in the mid-90s very crowded. In addition to the on-site restaurant there is also an ice cream parlor, the amusement park (6 or 8 rides including an old-style carousel), mini golf, and on Saturday night there was also live music. A very good Country band. This was their western weekend so the band fit the theme. They also had horses, rodeo activities, pony rides, etc. In walking around I noticed tennis, basketball, and shuffleboard courts as well. Shade for TTs and motorhomes is at a premium. There are a bunch of shaded tent sites. Our groups only complaints were the lack of shade and lack of grass. Nearly the whole campground is stone, though it is very well maintained and the sites very level. Finally, Swatara State Park is right across the street and there is a semi-improved road that takes you back to the the Swatara Park multi-use rail trail which features a beautiful walk along Swatara creek. The Appalachian Trail runs just on the other side of the creek and, in fact, there were a couple of AT'ers at the restaurant when we were there Saturday morning. We camped here in a Motorhome.

While many KOA parks are giving KOA's a bad name, this is one of the best KOA parks. This one is truely a big rig friendly park with no low overhanging trees, easy access, and easy level pull through sites. Nice small restaurant on site as well as a very nice pool, amusements, playground, entertainment, and more. Not that far off the interstate for an overnight stop. Clean, well maintained, and excellent staff. We camped here in a Fifth Wheel.

Big new KOA with numerous things for kids/groups -loads of space, pavilions, organized activity spaces, large restaurant, store filled with goodies kids will love, friendly management. At Exit 100 of I-81. Gravel level sites, no vegetation between, lovely area in general. If you like KOA's, you'll love this one as it is much larger, newer, less cluttered, friendlier management than most. They even have garbage pick-up! Family style campground. Our Verizon broadband air card and Verizon phones worked well. We camped here in a Motorhome.

Looks like a KOA should but usually doesn't. Amusement park rides looked to be in good condition, park very clean and nice. Not too far from office but couldn't get wi-fi. Scenic, somewhat remote area. We camped here in a Fifth Wheel.

Big Campground. Easy Access to and from I81. Lots of activities in season. WIFI Access works well but only available in vicinity of the office. Sites are large clean, and easy to access. We camped here in a Motorhome.

This is without a doubt the BEST KOA we have ever stayed in. The grounds were immaculate with some full-timers. The staff were excellent. There is a restaurant on premises with good food. There are trees that surround the campground but getting the satellite signal is no problem. All sites are gravel as well as the roads. There is a basketball court, a volleyball area with sand, movie theater, shuffleboard and horseshoe pits. You won't be bored here. They have a large store with RV supplies plus anything else you might need. I would definitely come here again. We camped here in a Motorhome.

This KOA is great. The staff is really helpful and friendly. I'll admit that a lot of their sites are gravel and out in the sun, but there are a number of sites along the tree line, and we had one of those. Our site was beautiful, large, and backed up to a small stream and trees that provided shade. The tenting area is back in the woods and looked very attractive. The bathrooms were immaculate. There are 7 really nice "family baths" near the tent area that consist of a residential style bathroom. There is an amusement area at the front of the campground, with about 4 rides, that looked fabulous for the pre-school aged child. The pool was closed, but large and clean. There are also a bunch of different sports courts. The arcade is huge. Across the street is Swatara State Park where you can kayak or canoe on the stream, if the water's not too low, or ride on the Swatara rail trail. We'll definitely be back here. We camped here in a Travel Trailer.

We camped here in a tent trailer with no air conditioning. We requested a shaded site which in fact was hardly shaded at all. Most of the sites in this campground are open and we were there on a very hot weekend. Would not recommend for someone without air conditioning. The facilities were clean and nice. The staff were friendly and courteous. This campground had a lot to offer in activities. Some amenities we liked: the large pool with water slide, nice arcade, evening entertainment, large campsites, small amusement park, and a full service restaurant. We would stay here again either in early spring or late fall to appreciate the warmth of the morning sun! We camped here in a Tent Trailer.

We loved this campground and only stayed for one night each way as we were passing through the area. We had a long pull-thru which was perfectly level and easy to enter and exit. Staff was very friendly. You have to eat here as the food is very good and fairly priced with good sized portions. Would have loved to have stayed longer. We agree the only thing lacking is a fishing pond, but everything else makes up for it and they deserve the rating. Grounds were immaculate and well cared for. One of the best koa's we have ever stayed at and we are gold card members so we have been to many. We will make it a point to go back to stay again. We camped here in a Travel Trailer.

Very family friendly campground. Friendly helpful staff. Everything is new & clean. We camped here in a Tent.

This is a good park, especially for the fourth of July. They have an amusement park for the kids with rides, and the pool has a small water slide. Pull-thru sites are not shaded but offer a good view of the fireworks show the campground puts on. Bathrooms are usually very nice, but this trip (this was our 2nd time there), they did not stay as clean as before. Also had more noisy neighbors than in the past and had to go all the way to the main gate to find security to ask them to quiet them down. We would return to this park despite the bathrooms and noise issues. We camped here in a Travel Trailer.

We camped here with a several other families in June and had a wonderful time. We didn't use the restrooms, so I can't comment on them, but if they are anything like the rest of the park, then they must have been clean and well maintained. The staff was pleasant and helpful, and they accommodated us all by keeping us all in a loop so that we were together. The pool was awesome, and the kids loved the mushroom and the slide. We will stay here again, without hesitation. We camped here in a Travel Trailer.

A great destination campground. See the web site and other reviews to get a sense of all the things to do. We were just passing through, and it rained the entire time, so we did not get to enjoy the many options available. Nevertheless, we were comfortable in this newer, clean, and efficient location. The individual bathrooms (toilet, basin, & shower) are wonderful. We camped here in a Motorhome.

This is an excellent park with a very helpful and friendly staff. The Pool is great for children as there is a water slide.Highly recommended. We camped here in a Fifth Wheel.

We fully enjoyed this campground. The facilities were impressively clean. This campground had several small play grounds plus a large one that made it wonderful for us, traveling with a preschooler. The small amusement park area was just great for the pre-teen crowd. We camped pre-swim weather so did have a chance to use the pool although it appeared clean and well kept. I don't recall a ton of very shady spots -- (I'm writing this 3 mos later) although there were plenty of trees around. I'd have to go back in the deep summer to see if its too very sunny but it was a good experience. We camped here in a Motorhome.

Only thing this place lacks is a fishing pond, but fishing is nearby. Staff is friendly, great place for kids. Restaurant is excellent. Being a newer campground, most of the sites lack shade and become toasty in the hot sun. There once, and our second trip is reserved. We camped here in a Travel Trailer.

Big Rig friendly, easy access of I-81, large sites, excellent camp store/restaurant, terrific arcade area with kiddie rides. Great setting in the Adirondacks for fall foliage made this a memorable trip. We would definitely return to this well kept and well managed rv park. We camped here in a Fifth Wheel.

Beautiful campground in the Appalachian Mountains. The big rig pull throughs were huge and and grassy. There is a beautiful view from the campground. There is an ice cream parlor, game room and a few rides that are owned by the campground. Every RV site has a free Satellite TV hookup. The Satellite TV has around 28 Channels and is provided by DirecTV. This service came in extremely clear. There are also many sites in this park that are Dish-friendly. The pool was beautiful and had a mushroom and water slide. The roads were well maintained. There was an excellent restaurant on the premises. The chef even came out and asked everybody how their meal was. The food was very reasonably priced. The store seemed to have quite a bit of stuff. I would recommend this campground campground. We camped here in a Fifth Wheel.

By far one of the nicest parks we've been to. We've been on the waiting list for 4 years to get our own site. Lots of activities for everyone, so you or your kids should never get bored. State park across the street for hiking and such. Restaurant is very reasonable with excellent food, in case you want to take a break from cooking. We visit several times each year. We camped here in a Motorhome.
