It is a pretty fun trail, but not five stars. The new stone creek trail was finished last year. It has some pretty fun sections, but it could use some more traffic to buff it out. It has an unfortunate number of switchbacks as well. The loop is a great ride, what it lacks in quality trail it makes up for in size and scenery. Not that it doesn't have some good sections, but there are better loops in the area.
The USFS rebuilt and relocated most of this trail summer of 2001 as part of the land exchange in the Bangtails. My company did the work. Key changes: The Northern end is now at the Bracket creek "Y" parking lot. Cross the new bridge and head South. Eight miles latter you hit the Skunk creek road where a parking lot was constructed. To start from this spot go up Olson Creek road to the junction and signs. Take the Skunk creek road .5 mi to the trail crossing and parking.If you go right here you will follow a new single track 2 miles to the Miles creek road. This is 1 mile up the Miles creek road from the signs-junction at the top of Olson Creek. Riders are urged to enter the trail from the road crossings as the old access route is on private land. From the Miles creek road crossing the new single track goes South and goes through old logging then nice trees, across the big summit meadow, down to the old Bangtail cabin site, and around the head of Stone creek, where it hits the Stone creek logging road. 2002 plans are to continue the single track down the ridge on the South of Stone Creek, ending at the locked gate, 1 mile up Stone creek. This will end up being the nicest 25 mile single track in the area. It can be a 35 mile loop if you add the 10 mile pavement up Bridger creek to Bracket Creek "Y"
