Description
Start at either the northern or southern end, both trailheads have bathrooms and maps. Starting in the north, switchback up the ridge east of the main trailhead and road. From there, continue south, and move along with excellent views of local wildlife (often deer) and the trees all around. Switchbacks on the south end will bring you back down to the valley floor. The final tenth of a mile will have you crossing the only real wet section--a creek crossing that is often dry.
