TTFs on TrailDrop, Rock Face, Rock Garden
A fun mid-technical loop with optional drops, small to medium sized rollers (both down and up), tight corners, roots, rocks, and one steep dirt pitch. Can be tough to follow in spots due to the spider web of trails that often cross it (many of them are unmapped). The whole loop is a pretty good time, in either direction (better direction indicated on map).
