What To Expect

Climb onboard the catamaran Marquesa, a spacious 69-foot vessel with plenty of deck space, on the water at Key West’s historic seaport. Enjoy the sun and sea breezes on this journey into the crystal blue waters off the coast for an exciting adventure.

Upon arrival at the Great Florida Reef, the only living coral barrier reef in the United States and the third-largest in the world, assemble the snorkeling gear and listen to a quick safety briefing with some basic instruction from the experts. Then it’s into the tropical water for swimming and snorkeling. The shallow reef waters are perfect for easy snorkeling. See more than 600 species of colorful fish, vivid corals, and other sea life. Watch for a wide variety of fish—parrotfish, angelfish, porcupine fish—plus turtles, lobsters, and plenty more.

Back on board, take a seat and kick back with a refreshing beverage—beer, wine, or soft drinks are included on this cruise. And keep an eye out for a pod of dolphins, which could appear next to the boat at any time.

The cruise concludes with a return trip to the Key West Seaport.

Traveler Tips

You'd be crazy not to take this tour the boat ride along out to the Reef is worth it!
We have snorkeled many places, but the inflation vest that helps keeps you on top, along with the noodle have never been offered.
It was a little chopper and challenging to move around, but it was OK.

The staff were knowledgeable and kept everyone safe. The boat staff was awesome. Beer and drinks were flowing nicely.
Excellent snorkeling trip
Luqman_B, Aug 2022
Great crew and great snorkeling trip. I am not a swimmer even then crew guide me to use floating noodles.
Good trip, a little pricey
Jeanie_J, Aug 2022
We really enjoyed the snorkeling trip we took. Our crew was awesome and hard working. We felt like the experience was a tad short but well worth it! We would recommend others to go and experience it!
Great boat and staff but tough snorkeling location.
Carlos_L, Aug 2022
Key West Florida Reef Half-Day Snorkeling Excursion was bitter sweet. We went as a family of 5 with a teen, pre-teen and a toddler and believed it was a great value for our group. We were the only family with a toddler so my wife and I already planned to split our time to snorkel while the other floats with our youngest kid. The staff was amazing, very attentive on the boat and also very attentive while in the water. We even saw one of the crew members specifically watching over our family since we had a toddler. We are experienced snorkelers but the instructions were clear and funny for any 1st timers attending. The equipment was clean and well kept so it made it simple to use. The only difficulty to rate well was the location we snorkeled. The waters were murky on a sunny day and we couldn't see any coral reefs or fish from the surface unless diving at least 3-4 feet in and it was still minimal views. Its a great boat ride, beautiful views in a clean and sleek boat with knowledgeable and friendly staff, but unfortunately the water and location was not what we expected. I'm not sure if that was only because of the day we went.
Not the best
Braden_S, Aug 2022
We have been on excursions in a few different places and this was our least favorite. The captain was not a people person and the crew wasn't fun like on other trips. They dropped us off in a patch of seaweed and jellyfish. Pretty much everyone got stung. The wine they bought was Yellowtail which is kind of gross. We would not recommend.
Key West snorkelling
John_N, Aug 2022
Boat was crowded with 73 guests. Limited space for seating. Didn’t see much. Water was very murky. Didn’t see hardly any marine life. Difficult to find actual location. Signage was poor to find actual boat. Pay parking wouldn’t accept credit cards. Luckily we didn’t get ticketed during our excursion.
The crew was great! Very...
Renee_C, Aug 2022
The crew was great! Very attentive and helpful. Plenty of snorkeling time. And Even though the water was a little choppy we were still able to find some cool fish and see the coral reef!
Kathlyn_V, Aug 2022
Captain Brennan and his crew on the afternoon snorkel trip were great!! They attentively each counted all of us on board both times before leaving our destinations. They were all so helpful and very knowledgeable about the reefs and the keys in general!
Ocean swimming trip
Vladimir_O, Aug 2022
Everything was great. Very nice ocean trip to take with kids. There is one “but” though:( there is nothing to watch when snorkeling. No fishes no corals. Just a ocean. So it’s not exactly snorkeling. It’s nice ocean swimming experience 7 miles from the shore. Which is fun to do
Very unhappy
Eliza_A, Aug 2022
We were confused where to go as there were multiple places and when we got there the boat was still loading. We already had out tickets and had done our waiver online but they refused to let us on the boat. They wouldn’t give us a refund and we had no time to reschedule for another day. Then the tour operator told Viator a lie that we arrived after the boat had already left. I’m unhappy with both the tour operator and Viator for not making it more clear where to go. The pickup and departure did not state the business name.
Captain and Renee were very helpful
FawadKhalid, Aug 2022

Not as Advertised
Savannah_Z, Aug 2022
Two of the three hours of this trip were riding on the boat. We booked this excursion in hopes to see all the fish and coral of Key West’s Barrier Reef but instead we’re taken to cloudy, dark waters. There were no fish nor coral. There was also no guidance during the actual 45 minutes of snorkeling. They emphasized getting tipped more than helping us find the “600 species” we were suppose to encounter. As avid snorkelers, we were very disappointed.
Don’t go
Brook_G, Aug 2022
We drove an hour by boat to a place to snorkel that had no fish for an hour and then an hour back. They should have told us that they couldn’t go to the reef so we could have gotten a refund. Just a scam to keep your money. Also they didn’t have enough seats for everyone on the boat so many people had to stand for an hour there and an hour back.
Not what I expected
Alexandra_S, Aug 2022
There was nothing to see while snorkeling. Even with the gear you couldn’t see more than 3-4 feet in front of you. The time on the boat itself was enjoyable with good music and plenty to drink, but the snorkeling experience was not one I would go back for.
No fish- complete fiasco
Cecilia_N, Aug 2022
Not one fish, nothing. Complete fiasco. They will just take you to a spot where there is no coral and no fish Do not book this
Boot trip &snorkling
Marcel_v, Jul 2022
The boot tour was nice, and crew did a good job. We expected more time to snorkle and the snorkling spot was disappointing. Not much to see.
3 hour tour
frances_l, Jul 2022
We had an amazing time. Staff was wonderful. Boat was clean. Bathrooms clean. Equipment was all sanitized. Would def. Recommend and use them again.

Russell_W, Jul 2022
