The third-largest living coral barrier reef in the world and the only one in the U.S., the Florida Keys stretch across 2,900 nautical miles from Key Largo to Key West. In 1990, they received the designation of National Marine Sanctuary, which protected some of the best opportunities in the country and maybe the world for generations to come. From snorkeling to diving in the Florida Keys, there is something here for everyone.

Key Largo: The Dive Capital of the World

Named for Cayo Largo, or long key, Key Largo is the northernmost island, and as its name suggests, it is a long key. Its location and size protect nutrient-rich waters, which nurture the growth of the corals. Although the increased popularity of fishing and diving threatened the survival of the reef in the early 20th century, By the 1950s, worried ecologists and environmentalists were launching conservation efforts, which led to the creation of John Pennekamp Coral Reef State Park and the banning of coral collection and spearfishing.

Today, you can explore Key Largo by snorkeling, scuba diving, canoeing, kayaking, and boat charters.
