Thain Creek Campground is the only campground in the Highwood Mountains. One of the 19 campsites can accommodate a maximum trailer length of 40 feet. The campground is usually open from May through the middle of fall. A nearby trailhead leads up to Windy Mountain and back on a 6 mile loop trail, offering scenic views of the surrounding plains and faraway mountains. Other hikes are along Briggs Creek or from the North Fork Highwood Creek Trailhead. Please heed seasonal trail closures, as all trails in the Highwoods close either September 1st or Oct 15th . All campgrounds on the Helena-Lewis and Clark National Forest are first-come, first-served. Reservations are not available. Camping is limited to 16 consecutive days in one location. A campground fee is required. Please pay at the self-serve campground fee station. Campsites cannot be reserved by simply paying for the site; camper must be present.
