Top Snorkeling Spots in Key West
The Florida Keys are home to the continental United States’ only living coral barrier reef, offering countless spots for incredible underwater exploration. Here are some must-visit Key West snorkeling sites:
- North Wall Reef: Located off the old Roosevelt Roads Naval Station pier, this area has transformed into a thriving living reef. Expect to see an abundance of fish, sponges, barracuda, and eels.
- South Wall Reef: Just south of the old pier, the South Wall is known for its small fish, diverse sponges, and larger marine life like nurse sharks, turtles, and stingrays.
- Dry Tortugas National Park: While a bit of a journey, the reefs around Fort Jefferson offer unparalleled visibility and pristine coral. It’s often cited as one of the best snorkeling experiences in the Florida Keys.

Protecting Key West’s Precious Coral Reefs
The Florida Keys National Marine Sanctuary protects 1,350 square miles of coral reefs, an invaluable ecosystem that supports countless marine species and protects the coastline. Responsible snorkeling is paramount to preserving this natural wonder.
Reef Etiquette for Snorkelers
- Maintain Distance: Always stay at least 50 feet away from coral formations. For kayakers and swimmers, it’s recommended to keep a 100-yard distance.
- Look, Don’t Touch: Coral has sharp edges and is easily damaged. Avoid touching coral or stirring up sediment, which can injure these delicate organisms.
- Leave No Trace: Never take coral pieces from the water or the beach. Corals are living animals, closely related to jellyfish, and play a crucial role in the ecosystem.
- Beware of Fire Coral: This invasive species, found in some areas, has white stinging tentacles that can cause painful stings. Be aware of your surroundings.
The United States Coral Reef Task Force actively educates the public on “reef safe” practices. If you witness violations of marine protection rules, please report them to the Coast Guard (VHF Channel 16) or NOAA law enforcement (305-744-7006).

- Sun Protection is Key: The Florida sun is intense. Liberally apply reef-safe sunscreen, wear a rash guard, and consider a hat for surface time.
- Stay Hydrated: Bring plenty of saltwater-friendly snacks and water to stay energized throughout your excursion.
- Never Snorkel Alone: Strong currents can be present in some areas. Always have a buddy, and ensure someone knows your itinerary and expected return time.
