Marathon Diving

Marathon is home to one of the most magnificent reefs in the Florida Keys: Sombrero Reef. Protected by the Florida Keys National Marine Sanctuary, is full of life, with an amazing variety of fish and coral. Like all of the diving in the Florida Keys, it is a quick trip from the shore and, as part of North America’s only living coral barrier reef, it is well worth a visit.

Sombrero Reef is only one of the many dive spots in Marathon offering an amazing experience for all skill levels. For the experienced diver, there are deep drop-offs and ledges carved by the Gulf Stream or deep water wrecks. There are miles of living coral reef, as well, for relaxing, shallow water dives. Here is a list of some of Marathon’s worthwhile dive locations. For more in-depth information, maps, or to rent tanks or dive gear, check out our list of Marathon Dive Shops.
