Are you planning to be in the area for a few days? If so, just go on across hwy 20 to Fort Bragg and stay. I recommend Pomo rv park which is just about a mile south of the junction of hwy 20 and hwy 1. If the train is running, it is a very long and boring ride from Willits to Fort Bragg. It's best to stay in Fort Bragg and take the half day trip to Northspur and back.
