About Looe Key National Marine Sanctuary

Looe Key National Marine Sanctuary is a vibrant underwater ecosystem located in the Florida Keys, offering exceptional opportunities for snorkeling, diving, and exploring rich marine biodiversity.

Wilderness Landscape & Natural Heritage

Located 5.3 nautical miles south of Big Pine Key in the Florida Keys, Looe Key National Marine Sanctuary is one of the most remarkable and accessible dive spots in the United States. It covers a shallow coral reef and surrounding ocean, with its coral formations reflecting the abundance of marine life it supports. The sanctuary was designated in 1981 to protect its diverse ecological formations, including elkhorn and staghorn corals, colorful sponges, and a variety of fish species such as parrotfish, barracuda, and angelfish. Notably, Looe Key is named after the HMS Looe, a British ship that ran aground here in 1744, adding a historical dimension to its natural beauty. The sanctuary's vibrant environment renders it an excellent location for snorkeling and diving. Visitors are often captivated by its living coral, which is home to myriad marine creatures. Educational tours and guided snorkeling trips provide visitors a more in-depth experience of the ecological significant area. Its underwater topography includes spur-and-groove formations, which are a favorite among underwater photographers. The sanctuary's appeal lies in its accessibility and the rare chance it provides to witness untouched marine environments in a protected setting.
