Level out-and-back trail. Starts paved at the trailhead and becomes a fire road past the park. When you reach Kent Lake you can turn loop back, or you can head left around the lake (which takes you all the way to Fairfax). When the lake is low you can head right and follow the trail all the way up to Bolinas Ridge.
From Hwy 101 in Marin, exit Sir Francis Drake Blvd. and travel twenty miles west towards Point Reyes. Continue a couple of miles past Samuel P. Taylor State Park entrance; turn right at Platform Bridge Rd. and park in the pullout on the west side of the road. Look for the paved path leading from the pullout.
