Why choose this Key West tour ?

Enjoy a 3-hour snorkeling adventure in Marathon Key at one of the world’s most incredible reefs. Sombrero Reef is alive. It is a place where parrotfish feed on the living coral while trumpetfish try to blend in among its branches. The reef is protected, so you can expect to see large schools of grunts and snappers swimming among large groupers hiding in the crags and looking for a meal. The great barrier reefs on our planet are precious. Like underwater rainforests, they teem with wildlife and colorful corals.
You are welcome to bring food and drinks with you.
