Hi Wolf,
We launched at the public access - parked on the blue-circled road.
From a view a little further out, we paddled from the red "x" on the western side to the red "x" on the northeast corner. It was a straight shot the morning we left as there was no wind but on the way back we followed the northern shore.
Cool route with some neat places to explore. Hope you enjoy planning and have an awesome trip this summer!
