Buffalo is a large campground just off U.S. Highway 20 on the banks of the Buffalo River at an elevation of 6,200 feet. Visitors love Island Park for its world-class fishing and outstanding scenery and wildlife viewing opportunities.

The Island Park area is renowned for its fishing; the Henry's Fork is known as one of the nation's best fly-fishing streams. Anglers cast for rainbow, cutthroat and brook trout and Kokanee salmon. Island Park Reservoir and Henry's Lake are nearby, both offering boating, water skiing and excellent fishing opportunities.
