Key West Snorkeling Tour: The Rise & Reef Morning Sail to the Coral Reef

Six miles south of Key West, the only living coral barrier reef in the continental United States rises to within ten feet of the surface. On a calm summer morning you can see it from the deck before you get in. This is the trip that takes you there, and it is the one we send every first-time visitor on.

This page covers what the reef is like, what the trip costs, how the morning and afternoon versions differ, and why the 9 am sail is the one to book.

Why this made our list

Snorkeling in Key West is not like snorkeling off a beach. The reef is offshore, so you need a boat, and the boat matters. This trip runs on the Sandie Cat, the newest and fastest snorkel catamaran in the harbor, which means less time motoring and more time in the water. The crew runs several trips a day, so they know which reef has the best visibility that morning and go there instead of to a fixed spot.

The second reason is that everything is included. Mask, snorkel, fins, vest, instruction, guides in the water, breakfast on the way out and a bar on the way back, all for a fare that starts around $46. That is the best value on the Key West waterfront by a distance.

The third is the review record: 4.8 stars across more than 21,000 reviews, the largest count of any snorkel trip in the Keys.

Why this operator

Four companies run reef snorkel trips from Key West, and we compared them on boat, reef choice, inclusions, price and reviews. This one won on value and volume. The other big catamarans in the harbor run comparable morning trips for $10 to $20 more and are a good backup if the Sandie Cat is full. The schooner trips snorkel the backcountry flats rather than the offshore reef, which is a different and quieter experience we cover on its own page.

What the Key West snorkeling tour is like

The trip runs about three hours dock to dock. Here is how it goes.

1. Check in at the Seaport. Find the snorkel booth on the dock at 201 William St, 30 to 45 minutes before departure. Sign the waiver online ahead of time.
2. Board and eat. Breakfast is laid out as you leave the harbor: juices, muffins, fruit and cereal. Find a spot on the bow net if you want the best seat.
3. Sail out. The catamaran heads south past the Key West Harbor entrance, through the channel and out to the reef, about 45 minutes. The crew fits your gear and gives the briefing on the way.
4. Anchor and go. At the reef the boat anchors in 10 to 25 feet of water. Guides go in first, point out the coral heads to work, and stay in the water with the group. You get about an hour.
5. Sail home. Once everyone is back aboard, the mimosas and draft beer open, the sails go up if the wind is right, and the boat runs back to the Seaport.

The reef itself is a low wall of elkhorn, star and brain coral with sea fans waving on top. Parrotfish crunch on the coral, sergeant majors swarm anyone who stands still, and barracuda hang motionless in the shade under the boat. Turtles and nurse sharks show up often enough that the guides mention them in the briefing.

Prices and what you get

The Rise & Reef morning sail starts at about $46 per adult plus tax and booking fees, with youth and child rates for smaller guests. The afternoon Dip & Sip starts at about $50. Both include every piece of gear, instruction, guides and the drinks; the difference is breakfast with mimosas and draft beer in the morning versus an open well bar (beer, wine, margaritas, rum runners, soft drinks) in the afternoon.

If you want to do more than one thing in a day, the Do It All pass bundles this snorkel trip with a parasail flight, jet ski time and the waterpark for one price.

Who it’s for (and who should skip it)

First-timers, families, and anyone who wants to see the reef without a scuba certification. The vest and the in-water guides make this a comfortable introduction, and plenty of nervous snorkelers finish the hour wishing they had longer.

Skip it if you are not comfortable in water over your head. The reef sits in 10 to 25 feet and there is no standing up. Non-swimmers can float in a vest with a noodle right beside the boat, but they will not enjoy the full reef. Children should be able to float on their own with a vest; the youngest regulars are around 6 or 7.

If you get seasick, book the morning trip and take a tablet an hour before. The catamaran is stable, but the channel can have a swell after a front.

Where to check in and how to get there

Check-in is at the snorkel booth on the dock at the Historic Seaport, 201 William St, on the Harbor Walk at the north edge of Old Town. It is a 10-minute walk from Mallory Square and about the same from mid-Duval. Arrive 30 to 45 minutes early; the booth lines up when ships are in port.

Parking downtown is scarce. Use the Caroline Street garage and allow 20 extra minutes. The live calendar is on the booking page.

Best time to go

Time of day. The 9 am sailing. The wind is lightest, the water is clearest, and you are back by noon with the afternoon free.

Time of year. May through September is the reef at its best: 85°F water, flat seas and visibility that regularly reaches 60 feet. Winter trips still run daily, but the water drops into the low 70s and a cold front will put a chop on the Atlantic side for two or three days. If you are here in January, book the first calm morning of your trip and bring a rash guard.

Local tips before you book

• Wear reef-safe sunscreen only. Zinc or titanium. The reef is a protected sanctuary and the crew will ask. Put it on 20 minutes before you get in so it does not wash off.
• Snorkel in a shirt. Your back is to the sun for an hour. A rash guard or an old t-shirt saves the rest of your trip.
• Do not touch the coral. Fire coral stings and the rest dies. Float, look, keep your fins up.
• Stay still for the fish. Sergeant majors and blue tangs come to anyone who stops kicking. Chase them and they leave.
• Hang near the bow net on the way home. Best seat, best breeze, best view of the sails.
• Pair it with a flight. The parasail boat leaves from the same dock, and an afternoon flight after a morning snorkel is a very good day. See our guide to things to do in Key West for the rest of the week.

The verdict

For snorkeling in Key West, this is the boat. The newest catamaran in the harbor, a crew that picks the best reef each morning, every piece of gear included, breakfast out and mimosas back, for less than $50. Book the 9 am Rise & Reef, wear a shirt in the water, and go in summer if you can.
