Everything but the kitchen sink
This place has it ALLLLL. Tent sites, RV sites w/electric and water, dry sites; boat ramp; playground, volleyball net, clothes lines, hot springs pools(2!); showers; camp store with ice; WiFi; wildlife(two mountain goats lead me in on the road); walking trail; shade trees(no hammocks allowed). And it is next to the Snake river. Seriously?? Ok, so the tent sites are really close to the RV sites, but with electric there aren’t any generators running. And the pools close at 9pm, which seems kinda early when the sun doesn’t set until almost 9:30. But I get it. And you are close to the town of Challis with two grocery stores and two gas stations and a Family Dollar. If you can’t find what you need, you probably don’t need it. Besides, you are going to spend all of your time in the water or playing land games. The bathrooms and showers are open 24hrs a day so you don’t even have to use the porta potties scattered around the property if you don’t want to.
