Lone Pine South Trailhead

Primitive trailhead with access to motorized Grizzly-Helena Trail as well as Mount Zirkel Wilderness. The Lone Pine Trail is easy to follow, however, a few sections are fairly steep, and this trail is difficult for horses. The Lone Pine Trail up to the Continental Divide and the route to Bighorn Lake are unimproved trails and maintained on a periodic basis. Campsites are scarce along the trail. This trail is very popular, so the opportunity for solitude is low.
