Washburn as no reservations. And San Simon state park. 805.772.6101
The lower campground does not have hookups but it has showers the upper campground has water only and no showers. The upper campground has chemical toilets. I much prefer the upper campground though. It's much more scenic and quiet. And they're almost always spots available.
Call the California State Parks service ask for San Simon State park and select Washburn, no hook ups but the lower campground has hook ups and showers.
