Experience a snorkeling excursion for 3 hours in the exciting Marathon Key, home to one of the most remarkable coral reefs on the planet - Sombrero Reef. This vibrant underwater habitat is teeming with life, where parrotfish feast on coral and trumpetfish are camouflaged amongst the reef. The protected nature of the reef allows for schools of grunts and snappers to swim freely, alongside groupers hiding in rock crevices in search of prey. The earth’s exceptional barrier reefs are treasures of immeasurable worth, similar to subaqueous rainforests, brimming with an array of aquatic animals and vivid coral. Feel free to bring along your own food and beverages.
