Trip Update-
We stayed at Bothe-Napa State park for a quick overnight. $35 for an unleveled small spot and a table. Probably not again.
Schooners Landing could be the best or worst place you ever stay. They put us inches away from a large tented fishing party. At 10:30 I had to ask them to turn the radio down (off). We moved the next day to a spot they reserve for full timers. A world apart. This spot was very quiet and a short walk to the beach. Schooners is a fish camp. If you have a boat, fish or dive for abalone it could work out great for you. If not well....
Jackson Forest was one of the best spots we've found and we had it almost all to ourselves (Thanks- Dan!)
