This living, breathing ecosystem stretches over 220 miles and is located just a few miles offshore from Key West.

The reef is an underwater rainbow, bursting with brightly colored corals that form an underwater landscape as diverse as it is beautiful.

Some of the best snorkeling spots are easily accessible from the beach, such as Fort Zachary Taylor State Park, where you can swim out directly to the coral reef.

Alternatively, a variety of companies offer boat tours that take you directly to some of the best spots in the Florida Reef. These tours often include equipment, making it easy even for those new to snorkeling.

Year-round Snorkeling: A Perk Of Tropical Climate

Key West’s tropical climate means that the sea remains warm throughout the year, making it possible to snorkel at any time.
