This is the local Route to Nacimiento Fergusson Rd. About 20 miles. This is what we take when Highway 1 is blocked in both directions. This path is rocky and completely unpaved. There are slow speed sections where there are several "neighborhoods" where locals live they are very friendly just don't speed through their area. Kids live and play up here. There are two sections where you need to watch your speed. no worry's though signs are posted letting you know you're in a "residential area." The Road head starts at Treebones Resort driveway. Go left onto Will Creek Rd. just keep trucking until you come to a fork in the road about 8-miles up. Follow the sign that says Naci-Fergusson/south coast ridge road. Things to be aware of: This road is used by locals. They drive really fast! This road is only passable with high clearance vehicles. Small/large trucks motorcycles ATV's. Can be done in a small car but definitely not recommended.
