Getting there
Access to the cabin is a short distance off I-15 south of Dillon. From Dillon, take the Dalys exit (#51) and turn left under the interstate, then right on the frontage road approximately 1/4 mile to an access gate and parking area on your left. You will need a combination to open the locked gate, and should lock the gate behind you to prevent other unauthorized vehicle use on this road. From here, the cabin is only 1/4 mile ahead on a lightly maintained gravel road.
