Dogs No Dogs E-Bikes Unknown There may be protesters at the trailhead but the ones I encountered were friendly. Designated trails, roads, and parking areas are open to visitor access from sunrise to sunset, seven days a week, and are open most federal holidays (closed on Thanksgiving, Christmas, and New Year's Day). Overview The trails on this ride will not be a challenge for even a beginner rider. However, the views are interesting, as is the history and controversy over public access.
