This trail is the bulk of what is known to mountain bikers as the 7th St Loop. It splits left from Ahwingna Trail at a large tree with a hitching post beneath it. Tree-covered and green, it's one of the best trails for miles around.
The trail is hard-pack with many wide switchbacks descending a north-facing hillside. Then the trail continues along the bottom of a small canyon, darting and turning through really fast lines beneath the trees. At the bottom, it bends left and starts climbing a small series of steep switchbacks. The climb back to the top is also completely tree-covered and a real pleasure to ride.
Cresting the last rise, follow the trail down a steep channel of rocks and stay left along the ridge trail for a half-mile or so to complete the loop.
