Sasse Mountain Trail #1340

The Sasse Mountain Trail begins at Forest Road 4305-118 and ends at Jolly Mountain Trail #1307. Motorized use is allowed only the first 1.5 miles, to Hex Junction.

From the south, the trail begins in a 1960s pine plantation, begins climbing steadily to the top of Hex Mountain. This portion of the trail is wide and chopped up in many places from logging roads. From Hex Mountain the trail follows the ridgetop, climbing and descending many times, ending at the junction with Jolly Mountain Trail 1307. This trail is rugged due to the fact that it is an old sheep driveway and has not been updated. The portion of trail from Hex Mountain Trail 1343 to Little Salmon La Sac Trail 1325 is closed to motorized use.
