Built in 1938, the Bishop Mountain Cabin housed employees of the USFS and BLM while they were on watch for wildfires. Now, it is available for rent through recreation.gov. Even if you are not renting the cabin, users of the trail can drive up to the gate just before the cabin for amazing views of Island Park Reservoir. The trail is a bumpy, packed dirt road that is often littered with ruts. 4WD should not be needed under optimal conditions, but high clearance will be your friend due to the scattered loose rocks.
