The Best Marathon Snorkeling Spots

The most amazing Marathon snorkeling spots located offshore – in between the Marathon Key (Vaca Key) and the barrier reef or just at the barrier reef.

You may begin your Marathon Key snorkeling from Coffins Patch. The place got its name from the ship which sunk in this waters transporting a load of coffins, however nowadays there is no sign of the wreck.

This site is situated rather close to the Marathon Key, just in 3.5 miles of Key Colony Beach. In the same time, Coffins Patch is placed closely to the barrier reef, hence, it is well washed by the ocean waters and offers both wonderful visibility and marine life profusion. Coffins Patch is featured by uncommon pillar corals and huge brain corals.

This snorkeling and diving spot includes around 6 patch reefs and each of them is really unique and beautiful. 10 feet is the average depth, but deep varies from patch to patch. The maximum deep is 25 feet.

One of the reefs is called The Donut and it received this name thanks to its shape. The round mound of rocks is covered with a great variety of sponges. The average deep is 15-20 feet.

Another patch reef is The Stake which name arose from the steel post standing in the sea as a mark. Site location in blue shallow waters ideal for snorkeling. The Stake is packed with fish and is must see during Marathon snorkeling.

Sombrero Reef is a highlight of Marathon Key snorkeling and unforgettable experience not to be missed. It is just snorkeler's heaven with all the best snorkeling ingredients – crystal clear water, ideal deep, a wealth of fish, sponges, and coral species together with wonderful topography. Sombrero Reef is situated just at the barrier reef’s edge and is 8 miles away of Key Colony Beach.
