This ride follows the coastline within Wilder Ranch State Park. The trail is above the cliff-band but you can hike your bike down to many of the beaches along the way. You can literally spend hours on this ride just to soak in the view.
You can do a loop by riding back on Hwy 1 but I would rather ride back the same way to enjoy a different set of views. This is a popular area so watch out for hikers.
