People travel from all over the world to snorkel in the Florida Keys. No snorkeling destination in the region is more famous than Marathon’s own Sombrero Reef, and with good reason. The 30 acre reef is thriving, and filled with incredible coral formations and massive schools of neon-colored tropical fish.

One of the reasons so many people join us on our snorkel adventures in Marathon is because Sombrero Reef is only 2 to 30 feet deep, so it can be thoroughly enjoyed without any fancy diving gear. Located in the Atlantic Ocean only six miles from Marathon’s shores, it’s easy to access and makes for an enjoyable ride where dolphins, turtles, and stingrays are often spotted en route.
