Written Directions
At US 101 and Cloverdale, leave the freeway and ride into town. On Cloverdale Blvd just north of town, turn left on Calif 128. Stay on 128 to Boonville.
Scenery
Um ... this really isn't a scenic ride. You'll be too busy enjoying the turns. There are sections of switchbacks and esses as well as high speed corners. But if you insist of glancing around, the road runs through typical California coastal hills of liveoaks, pastures, streams, and vineyards. Green in the spring, golden brown through the rest of the year. Boonville has good eats.
Drive Enjoyment
California has been rebuilding the state highways the last 2 or 3 years using federal Stimulus money. The roads are great--smooth, nicely banked and configured, well marked at super slow corners (20 & 25 mph corners).
Tourism Opportunities
Cloverdale and Boonville are fine, but there's nothing in between except wineries!
Motorcycle Road Additional info
Slower traffic is supposed to pull over; locals generally do but tourists sometimes don't. Most of the road is marked with double yellow lines. There's very little police enforcement. Weekdays the road is nearly empty except for commute times, when you'll meet maybe 20 vehicles.
