Stillwater Trailhead serves as a primary access point to the Flat Tops Wilderness, located at 10,259 ft southwest of Yampa with limited parking that fills quickly on weekends.

The trailhead offers three trail options including the Bear River Trail and East Fork Trail for hiking and backpacking, with restrooms available and a wilderness registration requirement.

Non-motorized boats are permitted on nearby Stillwater Reservoir, though potable water is not available at the trailhead; the site is typically open June-October depending on weather conditions.
