A little bit of public beach at the end of the street. The rest of the beach is privately owned. This cache is not on the ferry dock or accessible from the ferry dock. Park at coordinates and walk down. Benchmarkers, there is something here for you also.
There is so little public access to the beaches that I have used this several times to launch inflatable boats to cross to Blake Island. I used my Foretrex 401 (like the Navy Seals used in Somalia) which gives excellent coordinates. Have fun, you'll know it when you see it!
