Nice facilities… camp ground are close but there is enough coverage you don't notice others. The area has tons to do petroglyphs, fishing, hiking, geocaching, and semi-dark skies area.
Celebration Park is a lot of fun. The river and boulders in the canyon are beautiful! There is an old train bridge, (now a walking path) to cross and enjoy trails acrosss the Snake River. In the Park their is a fun museum, petroglyph trail, and Atlatl (ancient weapon) range. I enjoyed it as an adult but my kids had even more fun. We camped well out of the main camp area and had a nice grassy area all to ourselves. I recommend taking the time to hike to Halverson lake if you visit Celebration Park. Well worth the hike! I will definitely be camping here again.
Fishing, camping, and lots of trails! If you're not a fan of Porta potties then this place is perfect for you! They have really nice and clean bathroom. It is a lovely area with places to BBQ or have a fire pit. Both are already made up for your convenience just bring wood. There is a beautiful bridge, originally a train track, open to the public to cross onto the other side of the river. Please do not swim in this section if the snake river it has under currents that will drag you down. The actual camp ground sites are areas that have the sage brush removed, nothing too fancy. Lots of tumble weeds that are pushed together to create a path to the different camp sites.
I love this place! It is awesome for having little bon fires, or just cat fishing in the Snake river. I do not recommend swimming In the Snake though, the stretch of river that flows through this park is dangerous and pulls people under. Enjoy the river from either a boat, or the land.. but the cliffs are beautiful! I go to this park at least once a month!!
