Where do park to take the ferry ride? Are there bathrooms on the ferry? How long is the ride? Can we just drive up and buy tickets?

there are a few porta potties in a trailer 100 yards down the road... very clean for porta potties

There's parking nearby but get there early. There's a bathroom down some steps in the boat but Its tight. The length of the ride depends on what you book and you do have to pre book. They have a sunset tour for or you can book more hours. Set prices and I think they can take up to 15 people but not sure of that.
