The trail is short with a really steep section, that is also short... Ride the trail CCW, about 10 times. Going CW there is a 5 foot technical section that is tough because you're going so slow uphill. The view from the top of Bald Mountain is spectacular, and the trail is nice winding through the trees. You're in mountain lion country (posted at the trail head), so bring your slower friends.
From Boulder Head west on Mapleton. Once it turns into Sunshine Canyon Drive (County Road 52), go about 4.5 miles until you get to the Bald Mountain Scenic Area on the south side of the road.
