This is a small (less than 25 sites) campground in the Caribou-Targhee National Forest near the Snake River. The river is an attraction for fishermen.
Given the name, there must be a waterfall, right? Yes, if you come toward the campground from Rt 26, the waterfall is on your left just after the pavement ends. The waterfall is worth a stop on your way to or from the campground; the campground is about a mile past the falls.
This is a typical Forest Service campground with plenty of space between large sites. There are vault toilets, water spigots and a trash dumpster. You can use the dump station at the Palisades Reservoir during and at the end of your stay without paying $5 if you show a receipt validated by the campground host.
Double sites have 2 picnic tables and you must pay a double fee ($24) even if it's the last site in the campground. There is no discount for NPS Senior Pass holders for a double site. (This is standard at Forest Service campgrounds. Remember, hosts don't make the rules.)
Bringing an ATV? You can't ride one in the campground, but there is an ATV parking area.
