About
Riverside Campground offers a scenic riverside camping experience along the Henry's Fork of the Snake River in Idaho's Island Park area. The campground features 57 single-family sites plus one group site that accommodates up to 40 people. Each site includes a picnic table, campfire ring, and grill. Vault toilets, potable water, and trash collection are provided, though there are no electrical hookups. At an elevation of 6,200 feet, the campground is shaded by lodgepole pines with aspens dotting the landscape. Summer wildflowers are abundant, and wildlife sightings of moose and deer are common. The Henry's Fork is renowned for fly-fishing, with healthy populations of rainbow and brook trout. The river also supports tubing, canoeing, kayaking, and rafting. Nearby Island Park offers hundreds of miles of hiking, biking, horseback riding, and ATV trails. Island Park Reservoir and Henry's Lake provide additional boating and fishing opportunities. Yellowstone and Grand Teton National Parks are close enough for day trips.
