Snorkeling Tour Key West

Snorkeling in Key West is a half-day trip by boat, because the reef sits offshore and no beach on the island gets you onto it. I compared five snorkeling tours, from $49 to $134, and every one includes the gear. Prices are in US dollars, checked in October 2026, and the booking links are affiliate links, as I explain on my about page. For the rest of the water, see my guide to boat tours in Key West.

My pick is the Fury reef snorkeling trip with drinks and a sunset option: $49, 3 hours, rated 4.5 from 609 reviews. It is the cheapest in the list and has the second-most reviews.

Snorkeling Key West Fl

Snorkeling in Key West, FL starts at the Old Town piers, not at a beach, and the trips all use a boat to reach the reef. The Florida Keys National Marine Sanctuary, which the sanctuary office manages, covers the waters around the island chain. The Fury listing calls the reef North America’s only living coral reef, and I take that as the operator’s claim rather than something I checked.

The Fury reef trip is the one I would start with. You choose a morning, afternoon or sunset slot on a 65-foot catamaran, and the listing says you get snorkeling gear, professional instruction, sodas and water, a fresh-water rinse and alcohol after the swim. The drink depends on the slot: mimosas, margaritas or rum punch. A towel is not provided and a wetsuit is a seasonal rental. It departs from the Fury booth behind the Opal Key Hotel, 241 Front Street.

Key West Snorkeling Tours

The Key West snorkeling tours in my data sort into three styles. The simple reef trip is the Fury one above. The wildlife combination adds dolphins, which is what the Fury eco cruise and the Sunset Watersports sunset cruise do. And the longer day mixes snorkeling with food or paddling, as the Sebago seafood boil and the Danger Charters excursion do.

The Fury dolphin watching and snorkeling eco cruise is $73 for 3 hours and has 871 reviews at 4.6, the most of any boat trip I compared. It runs on a 45-foot power catamaran and lists snorkeling equipment, a guide, water, soda, and beer, wine or champagne. It meets at the Fury kiosk in front of the Conch Republic Seafood Company, and parking is paid downtown. Reviewers praise the guides, and one calls the dolphin watching the best they have had. If you want one trip that covers a reef and dolphins, this is the safest of the five.

Snorkeling Key West Tours with Sunset

If you want snorkeling in Key West with a sunset, the Sunset Watersports dolphin and snorkel cruise is the other trip to look at. It is $80 for 3 hours, rated 4.4 from 573 reviews, and heads out to the small islands inside the Key West National Wildlife Refuge before you jump in at the reef. The listing includes safety and snorkel gear and draft beer. Hotel pickup and gratuities are not included.

Because it runs on a late-day schedule, check the sunset time for your date before you book. By my calculation from sunrise-sunset.org for the island’s coordinates, mid-month sunset is about 6:01 PM in January, 7:37 PM in March, 8:19 PM in July and 5:41 PM in November, in local clock time. My sunset cruise page has the whole table. If dolphins are the main reason you are going, my dolphin watching page puts the three dolphin trips side by side.

Snorkeling Key West Reef: The Longer Days

Two of the five trips give you more than a swim. The Sebago catamaran snorkel is $70 for 4 hours and visits two snorkeling locations, such as Sand Key or another nearby reef, according to the listing. It adds an all-you-can-eat seafood boil and a premium open bar. It has 4.7 from just 21 reviews, so I read it as a good bet, not a proven one. The meeting point is on the Harborwalk at the Historic Key West Seaport, at the next-to-last shop on the right as you walk down Lazy Way Lane.

The Danger Charters afternoon excursion is $134 for 4.5 hours on shallow-draft schooners, limited to 20 guests. You sail, snorkel and kayak through mangrove channels, then watch the sunset, and the listing says it provides masks, fins, snorkels, wetsuits in the winter months, snacks, soda and water, with wine and beer after the watersports. It has 4.8 from 24 reviews. It departs from the Danger Chandlery Store at Opal Key Resort and Marina.

Snorkeling Key West Coral Reef: What to Pack

A snorkeling tour in Key West is easier to enjoy with the right small things. Both Fury listings say a towel is not provided, and the Danger Charters listing asks you to bring a bathing suit, a hat, sunglasses, sunscreen (preferably reef safe), a camera and photo ID, plus a sweatshirt in winter. It lists wetsuits as provided in the winter months, and the Fury listing says a wetsuit is available to rent seasonally. I would take that as a sign that the water is cooler in the winter months and pack accordingly.

Gratuity is customary on all of these trips and is not in the price. Fury adds an automatic 10 percent service fee for groups of eight or more, and the listing says to have cash or a card at check-in. Read the weather the day before: the cancellation text lets you cancel free up to 24 hours ahead, and that is the window to use if the wind is up.

Who Each Snorkeling Trip Suits

Families and first-timers will find the Fury trips easiest, because both list instruction or a guide and both are 3 hours, short enough for children to stay interested. Groups that want a party will prefer the Sebago boil with its open bar. Couples who want an evening out should look at the Fury sunset slot or the Sunset Watersports cruise, since snorkeling in Key West at the end of the day pairs well with the light. The Danger Charters trip is best for people who get restless: it moves from sailing to swimming to paddling in 4.5 hours, and its 20-guest limit keeps the boat uncrowded.

Which Snorkeling Trip I’d Book

For snorkeling in Key West on a budget, I’d book the $49 Fury reef trip. For a reef and dolphins, I’d pay the extra $24 for the 871-review Fury eco cruise. For a social day with food, the Sebago seafood boil is the one, and for a full active afternoon, the Danger Charters excursion. None of these is a deep-water or technique-focused course, and I would not choose one if I wanted a diving certification.
