A little north of Sonoma county, (about 70 miles north of San Francisco) Hwy 1 intersects with a road named Stewarts Point Rd. Make a right on it. (If you went left you would be in the ocean.) It starts with several miles of typical CA paved goat trail followed by at least 25 miles of the finest on-camber, intersection-free, high-speed sweepers. There are two "slow" turns marked with 20 mph advisories, but you can get though them about 60mph if you don't mind dragging you peg feelers a little. One is the only seriously decreasing radius turn on the whole road. Take care--you will be totally zoned when you get to it. This is the closest thing to track riding on the road, I have ever experienced. The road surface quality is awesome, some of the corners even have "run off", (although some have guard rails and cliffs.) Best to go on the weekdays and usually there will be no cars or cops there. It has become popular with sport bikers in recent years so there has been some police presense on the weekends. Best to take a slow run through your first time and check for cops. You will never see them in the goat trail section. Overall it is a great ride. Not to mention, the whole ride up Hwy 1, to get there is beautiful, with great twisties, great views, but a few too many slow motorhomes. There are passing lanes about every 3-5 miles on Hwy1. Remember, the cops rarely pull you over for speeding on a two lane road in California. But they will get you everytime for crossing a double yellow line.
