Trail runners, mountain bikers, and anglers have reason to seek out Tongue Canyon Campground, a free, dispersed-style area managed by the Wyoming Game and Fish Department within the Amsden Creek Wildlife Habitat Management Area. A small river runs through the canyon, giving campers a place to sit streamside in the morning or watch someone cast at sunset. The access road is paved and in good shape, passing horse farms and river scenery on the way in, and the drive takes less than ten minutes from campgrounds around Dayton.
Sites are marked with small brown tent signs that can be hard to spot, though a map at the entrance shows their locations. Some sites include fire rings and picnic tables; others do not. Pit toilets are on-site. The campground draws a mix of trail users, particularly during events like the annual Bighorn Trail race, so summer weekends can bring more neighbors than expected on a typical visit.
"For free? Doesn't get better than this," noted one camper, pointing to the trails and the riverside setting as the main draws. The Tongue River Campground sits about 1.2 miles east for those who want a nearby alternative. Cell service is listed as available, and reservations can be made in advance. Pets are welcome. Campers who arrive early on a Friday in June have found spots even during busy weekends, making it a workable stop for those passing through on I-90.
