Explore a vibrant living coral reef just 6 miles (9.5 km) south of Key West, in the National Marine Sanctuary. No matter your age or level of snorkeling experience, hop in to swim among the more than 150 species of fish and 50 species of coral that can be found in these warm and crystalline waters.

Sail to Florida Reef, the only living coral barrier reef in North America. Take in the beautiful views from aboard a 69-foot (21-m) catamaran and relax on over 2,300 square feet (214 sq m) of deck space. Professional instructors guide you through a course on snorkeling, covering every step of the process even for first-time snorkelers.

When you're ready, jump in and paddle through the shallow waters to gaze at flitting schools of colorful fish and the unique coral formations of the reef, believed to be over 5,000 years old. After your snorkeling adventure, have a drink in a sunny spot back on the boat during the journey back to shore.
