Sawmill Campground has 3 small, tight campsites; each with a fire ring and a picnic table. Sites to pitch a tent are small and limited by aspen within the campground. Parking is limited. Large RVs and trailers are not recommended. A single-unit, ADA-accessible SST vault toilet is found at the campground. Individual campsites are not considered ADA-accessible. An excellent site for a small picnic near a creek. Aspen trees shade the campsites.
From Ketchum, go south on ID 75 approximately 6 miles to the East Fork Big Wood River/Greenhorn Gulch traffic light, then go east (left) on Forest Road #118 approximately 11 miles, through the old mining town of Triumph, along the East Fork of the Wood River, to reach Sawmill Campground.
