Stone Island

Isla de las Piedras - is the island lining the harbor channel, reachable via a short ferry ride. There is a long and wide beach with safe waters and a dozen or more palapa restaurants where locals and tourists hang out. You can rent canoes and other stuff - and local tour guides drive you around on flat bed trailers pulled by large tractors.

Coming from one of the ferry docks:

Looking back towards the lighthouse hill: I am sure high tides will cause some flooding of these palapa places, not to speak of a hurricane - when they probably disappear into the sea!
