Reservations are available at Thompson Flat Campground, a Forest Service site in Sawtooth National Forest running $8 to $50 per night, with a season that typically runs July through October. The roads are paved until the turnoff for the campground, which sits near Lake Cleveland in the Albion Mountain range above Burley. Sites accommodate rigs up to 60 feet, and Verizon users have reported solid cell coverage from a tower on a nearby peak.
The campground has a large number of sites, but they run close together, which affects the experience depending on when you visit. Weekends can draw significant crowds, with some visitors reporting loud gatherings that made sleep difficult for tent campers. Weekday stays in late September tend to be much quieter, with only a handful of sites occupied. Wildlife activity is visible around the campground, including antler rub marks on trees left by deer and elk. Each site includes at minimum a metal fire ring, a BBQ grill, and a picnic table, with some larger sites featuring oversized fire rings suited to group use.
Tate W. describes the sites as having "tons of trees," and photos from visitors confirm a mix of conifers including fir. Anglers can reach Lake Cleveland roughly two miles away, where fishing access is available. A fire lookout tower and interpretive area at Mt. Harrison, about three miles out, provides open sightlines across southern and western Idaho. Campers wanting more site spacing can look at Bennett Springs, a nearby alternative in the same area.
