The Coffins Patch Sanctuary Preservation Area is located about 4 nautical miles off Key Colony Beach and is brimming with marine life, including tangs, jacks, stingrays, nurse sharks, grouper, lobster, butterflyfish, and moray eels. As the “Hidden Gem” of Marathon, make sure to dive in this 25 feet of water reef.
