About
Mill Flat Campground is a developed, no-fee campground managed by the Minidoka Ranger District in the Sawtooth National Forest. The campground features 7 individual sites in an open canyon setting, with gravel parking spurs for vehicles. It accommodates both tent and trailer camping, though facilities are primitive with vault toilets and no potable water available. The surrounding area offers recreational opportunities including trout fishing in the adjacent stream and access to an extensive trail system winding through the mountain canyons. Horses are not permitted within the campground itself. Campers are limited to 2 vehicles per site and must observe the 14-day stay limit within any 28-day period, after which they must leave National Forest lands in the Minidoka Ranger District for at least 14 days.
