We had an amazing time on our trip! the crew was amazing and were amazing teachers for those who have never snorkeled before. Drinks were flowing and sights were amazing when snorkeling. Also they allowed people to jump off the side of the boat if they wanted to and me and my friends took full advantage of that! So much fun and would go again!

Seeing all the colorful fish was surreal it was amazing so many different species coral was beautiful the crew was amazing and so friendly it was a perfect day and the water was amazing. I would recommend this to anyone who is visiting the keys.

What To Expect

At your appointed time, board the catamaran Marquesa, a spacious 69-foot (21-meter) vessel with plenty of deck space, at Key West’s historic seaport. Enjoy the sun and sea breezes as you journey into the blue waters off the coast.

Upon arrival at the 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, jump 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 coral, and other sea life.

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.

Absolutely amazing! We had such a great time, we went back a second time! The crew is more than hospitable, helpful, and very well educated! The drinks were great, the views were beautiful, and we saw plenty of Marine life! Would go back for a third snorkel excursion for sure!

Snorkel Paradise

Robert_A, Mar 2026
Excellent and over impressed. Staff were great and even in a “Sporty” day they made sure all who wanted to give it a go got a chance.

Response from Host, Mar 2026

Thank you for the awesome review, Robert. We love a little “sporty” day on the water—it keeps things interesting. Our crew always makes sure everyone gets a chance to jump in and have fun, no matter the conditions (safely). Glad you were impressed and hope to have you back for another adventure soon!

Nice Option during a Visit

Dale_R, Mar 2026
Great overall experience. Ship crew were top-notch. Tons of space to stretch out during the cruise to/from snorkeling location (approximately 45-min each way). Quality snorkeling gear provided for use and detailed instructions provided to make the best of your time in the water. Nice selection at the open bar and long “operating hours”. Saw lots of different fish but plant and coral areas were a little disappointing. Snorkeling is not one of my favorite pastimes but this experience seemed just right based on everything provided. Tip: if you want to maximize your time in the water take one of the authorized side exits vs the stairs in the front of the ship. I believe the trip is maxed out at 75 pax. We had 73 so it took quite a bit of time for the last person to get in the water using the stairs. Enjoy!

Response from Host, Mar 2026

Thank you for the detailed review! We’re glad you enjoyed the crew, spacious boat, quality gear, and overall snorkeling experience. We appreciate your tips for maximizing time in the water and feedback on the coral and plant areas, this helps us continue improving.

Best snorkel trip in the Keys.

William_v, Feb 2026
Top notch crew as usual with this outfit. Professional, friendly and helpful. Had a great time in the reef and the ride. The boat is huge! Lots of space for everyone. Drinks are a bonus. Thanks for always making our yearly keys trip memorable.

Fun afternoon sorkel trip on a big catamaran

Sarah_C, Jan 2026
It was exactly as we anticipated. There were a lot of people on the boat, but the staff was great and well prepared. The equipment they provided was in good condition, but I felt the water wasn't that clear and I had a hard time seeing a lot on the reef.

Response from Host, Jan 2026

Thank you for sharing your experience! We’re glad our staff and equipment met your expectations and helped make the trip enjoyable. We’re sorry the water clarity made it harder to see the reef, and we appreciate your feedback. We hope to welcome you back for another adventure!

Very bad experience

Ishita_K, Dec 2025
Very rude staff.. 10 mins of snorkeling in 30 feet water. They were in big rush.. just roamed around in the water to kill time. Very rude staff. Very bad experience. Over crowded too.

Response from Host, Jan 2026

Thank you for sharing your feedback. We’re very sorry to hear that your experience did not meet expectations. We strive to provide attentive and enjoyable snorkeling trips, and it’s disappointing to hear that the staff came across as rude and that the time in the water felt rushed.

We would love the opportunity to make this right if you want to reach out directly.

Enjoy now & again

Family Christmas trip to Key West

Greg_H, Dec 2025
Had a great time! Friendly and knowledgeable crew. Great spot for snorkeling. Enjoyed the free drinks too!

Attitude Adjustment Needed

Stefanie_G, Dec 2025
Actual snorkeling was cool but mediocre experience because the boat operators and instructors were jerks (unfortunately, especially to foreigners). They could have been a lot more patient and kind, especially with those who needed extra help or were timid. Will look for a different company next time.

Response from Host, Dec 2025

Thank you for sharing your feedback. We’re very sorry to hear about your experience with our staff. Patience and kindness are essential, and it’s unacceptable that you felt poorly treated. Your comments will be shared with our management team to address this and improve our guest experience. We appreciate you letting us know and would love for you to reach out directly. We would appreciate the chance to make things right.

Nada

Eric_F, Sep 2025
Booked the excursion, called the office. They said, check-in time was 1230. That was incorrect. The boat left at 12:30. We missed the trip. .They did not refund

Boat was too crowded....

LeahGrace, Aug 2025
Boat was too crowded. Crew and captain weren’t friendly. Boat was small. There are better trips for the same price..try sunset charters.

Response from Host, Aug 2025

Thank you for your feedback. We're sorry to hear the experience didn’t meet your expectations. We always aim to provide a welcoming atmosphere and a memorable trip, so it's disappointing to hear we fell short during your visit. We appreciate you sharing your thoughts, they help us improve. If you’d be open to it, we’d love the chance to learn more and see how we can do better in the future and make this right.

Disappointed

Angela_H, Aug 2025
Too many people and not enough snorkeling. It took an hour to get to the spot,15 minutes to park. Only 45 minutes of snorkeling and they don’t serve drinks until the ride back.

Response from Host, Aug 2025

Thanks for coming out with us! Yes — the reef is about an hour’s ride away because it’s 7.5 miles offshore and part of the third largest reef system in the world. Depending on wind, current, and swell, it can take our captain and crew a little extra time to safely moor inside the sanctuary (safety first, even if Mother Nature takes her time). And while we know an early drink sounds tempting, the Coast Guard isn’t too keen on us serving cocktails and then sending guests face-down with snorkel masks in the open ocean. That’s why we save the bar for after you’ve enjoyed the beauty of Key West beneath the waves. Glad you joined us!
