We have camped here two seperate times. The first time we were in the water/electric sites close to the beach. These are very nice sites. This time we stayed in site 2. It is a full hook up site. These sites were mud pits. Unlike the nicely graveled picnic table areas of the "beach front" sites, these sites have paved (and level) pads, but the site itself is just dirt so when it rains it becomes muddy. Unforunately it sloped toward the pad so the biggest puddles were just outside our door. It's a nice walk to the beach, mostly flat and the beach is huge. I don't believe they have a playground (if they did we never found it) ,but the sites are set up in little cul-de-sacs which are nice . When you have small children, they can play in the center "forest" area, or they can ride their bikes around the loop without going out of earshot. This is a decent campground but I think it would've been worth dealing with just water/electric to have the nicer site.
This is our favorite Washington State Park. The sites are level and paved and the area with the picnic table is gravel (so you don't have to walk around in mud if it rains) with plenty of room to have a canopy over your table and the awning out without fear of catching them on fire. We stayed in site 43. The walk to the beach is easy, there's one very small hill (literally a couple of feet long). The bathrooms are each in their own "room" as are the showers. They were regularly cleaned and restocked. The sites are set up in cul-de-sacs which are great for small kids to ride bikes around and not be out of ear shot and there's an "island" of trees and such where the kids can also play. The only problem we had with this park was with one of our neighbors who kept parking his extra vehicle out in the loop to load and unload and would leave it there for a long time. People couldn't drive around and it was hard to get the rangers or hosts to come when it was happening. But that is more dealing with an inconsiderate neighbor. There is a new wood-fired pizza place set up where the shuttle used to be and they deliver to the campsites which was fun (if you want Wi-Fi go eat there and they have it).
We did not have a very good experience at this campground. We reserved a site for our 27' trailer but in order to fit in the site they assigned us (they were aware of the length of our trailer) we had to move the firepit and the picnic table. Most trailer campers were unable to park their vehicles with their trailers because the spaces were not deep enough, everyone parked around the playground. Most spaces didn't have room to put out the awning or even really fit the picnic tables between sites. Fortunately we weren't spending much time there. Their sewer system actually backed up due to the rainfall so when we went to leave we had trouble emptying our tanks. My daughter hated using their restrooms because they smelled. The only positive I saw was that the playground had a big sandbox with toys in it for the kids to play with.
