This trail forms the northern segment of the trail network connecting to Boundary Trail to the east and South Lost Creek Trail to the south. This playful trail runs through undulating forested montane to subalpine terrain, half of which was affected by the 2003 Lost Creek Wildfire. There are mild elevation gains, punctuated by some moderate climbs and rocky terrain.
This is a multi-use trail, so expect to see motorized users.
