High Point

A nice south bay loop taking in some of the better trails. Two paved sections (Miller Ranch road to the east, Proctor Valley road to the west) connect the Sweetwater and Proctor Valley refuges, lots of great single track. Best direction is clockwise. Can be accessed from multiple points; low point is the best start, Sweetwater county park.
