This is a beautiful park, really busy in the summer, but on the edges of the season, a pleasure to stay at. I had occasion to speak to the park folks several times, and found them to be friendly and knowledgeable, I hope I have the opportunity to return!
This is a beautiful park situated along the Snake river, I would guess that in season it would be very busy. During our visit in early October, even on the weekend it wasn't busy. The spaces are set far apart, so you have the privacy that really only comes with the State park system. I highly recommend this park!
My wife and I have been camping for 15+ years, and this is the first time we have ever driven away from a campground as soon as we arrived! We pulled in and parked, and my wife went to walk the dog while I registered. Before I could get out and close the door on the coach, I heard a woman sternly telling my wife that she needed to take the dog off the property, that they were not allowed to do their 'business' in the campground. Now I'm used to carrying a bag when I walk the dog, but no campground has ever told me to take the them off the property (presumably to the neighbors). I asked this person if the dogs were a problem, and she answered 'not if you take them elsewhere, that animals were not allowed to take care of 'business' in the campground. I have to say that more than this unreasonable rule, her attitude made me feel totally unwelcome, no hello, no introduction, no welcome, just take your animal to the neighbors! I recommend anyone traveling with animals to stay as far from this place as possible, that shouldn't be hard to do, the area has several other very nice parks that actually make you feel welcome when you arrive.
