Stayed at the "Cottontail" Cabin. It felt like we were the only ones there. Very peaceful and quiet location. Beautiful sagebrush and grasslands. Only wished I could have stayed longer.

Stayed over the weekend in September, not crowded, peaceful, clean, cannot comment on the bathrooms or showers as I have a travel trailer. Has electric, water, and common dump station. Was definitely pleasantly surprised. Will revisit in the future if in the area.

You know the sleeper in fantasy football? That’s this park - it doesn’t look like it will be amazing, but it’s super peaceful and has great trails for both humans and dogs. Has fishing spots for those that fish and the snake river is the most beautiful river ever. It’s our favorite. If you value peace and are not looking for your campground to entertain your kids or dogs so you don’t have to, you’d probably like this place.

Absolutely amazing! I highly recommend checking out the visitor center. The staff was incredibly friendly and helpful, making us feel very welcome. If you have kids, definitely stop by and grab yourself a junior Ranger backpack. The plant walk is a must-do. The campsites are spacious and super clean, probably one of the best we’ve stayed at. There’s so much history here, and it’s absolutely beautiful. We stayed in the lower campground during the Fourth of July weekend, and it wasn’t busy at all. If you want to be away from the road, definitely recommend the lower campground. The park offers a variety of activities, including disc golf, boating, fishing, kayaking, and paddleboards (of course, you have to bring your own). There are so many trails to hike as well, and you can also see the wagon ruts, which I found absolutely amazing. We also enjoyed seeing all the wildlife, from bats to lizards to birds. They had showers and bathrooms throughout the park, which were very clean. The only downfall was that there was no light in the bathrooms, so it was pretty dark at night.
