What a great place. Boldt Castle (pictured), Singer Castle, island mansions, the Antique Boat Museum in Clayton, and a host of other things to see and do. Beautiful time of year too. Mid 70's with low humidity.
In the late 80's, I camped there once in the early spring. It was chilly but I don't think I have ever slept so well. And we took a small boat out on the water...crystal clear. Gorgeous place!
