Going clockwise, it starts out as a rolling, swooping single track. Fir needles, a few roots, nice. After you walk your bike two hundred yards on the Pacific Crest Trail, the trail changes to more rocky single track with steeper pitches. You cross a few roads, but there isn't much traffic up there. The part around Clackamas Lake is pretty easy--very dusty in late summer. The latter part of the ride on the east side of Timothy Lake has a few technical spots, but nothing too serious. Come out on forest road 57, cross the dam, and you're done. The trail itself can be a good workout for beginners and experience in riding the trail will vary whether you ride it clockwise or counter-clockwise.
