The Devil’s Causeway follows a narrow strip of land that connects two major sections of the Flat Tops. Both sides of the trail are 60′-80′ cliffs with steep talus slopes dropping another 600′-800′ into the drainage below. The rough, 3′ wide crest is a spot any hiker or climber will never forget.

The trail parallels the north side of Stillwater Reservoir for 0.8 miles, reaching a registration/information board at the junction with trail #1120. Head right (N) at the junction and pass Little Causeway Lake at mile 1.6; good camping and fishing at the Lake. From here the trail climbs along and through talus slopes to a watershed divide at mile 2.3. A side trail on the left makes a steep ascent to the Devil’s Causeway, mile 2.8.

On the way to Stillwater TH:

Mile 7 to Mile 17 – Bear River Designated Dispersed Camping Campground

Whether you are looking for solitude or group capability, open air vistas or sun dappled forest, with 32 individual campsites available, there is a dispersed camping site for everyone. Some sites are in close proximity to trailheads or fishing areas and some take you off the beaten path. Sites are marked with numbered camping posts.
All the dispersed campsites have Forest Service fire grates which must be used for campfires and most of the sites feature picnic tables, except for the grouped sites where self-contained RVs often camp. Prepare for rustic camping. Drinking water and toilets are available a few miles away at Bear Lake, Horseshoe and Coldsprings campgrounds. Toilet facilities are also located at dispersed sites #3-4 and #9-10.
