This is best done as a night dive in my opinion (be sure to bring 2 lights!). This site requires a long swim out to the dock. Calculate slack accurately or you will hate life. Walk along the beach until you are closest to the middle of the dock. Begin the long surface swim out. Be sure to take a accurate compass reading back to shore. Once you arrive at the dock descend and begin your dive. Explore inside and around the pilings. Leave enough air to make your way back to shore underwater. There are some interesting things you will come across.
