Sunset Cruise

I would highly recommend the 1/2 day trip. Great staff Captain Mary and her crew Connor and Trevor were awesome and answered everyone’s questions. We had a blast. It was our first time to snorkel and they were very patient and helpful. The drinks were good too. Good time had by all.

It was a small personalized experience. Captain Mary and first mate Frankie did everything possible to make the trip one to remember. Great food, drink, and experience. Frankie even gave us a great lesson on the Keys and the history. We snorkeled and took kayaks around and through the mangroves.

Sailing and snorkeling all in one.

Our sailors were a great atmosphere to hang around with. Both of them were so fun and professional with safety in mind. It was a little choppy but the sights underwater were great! The reef is right there and shallow. Not terribly deep. You're given a pool noodle to float with.

Fantastic snorkeling and dolphin spotting too!

Beautiful weather, clear views and two great reefs! The crew was super friendly and so much fun. The capacity of the boat was perfect, plenty of space to spread out and be comfortable. Highly recommend! Top it off, the Captain spotted a dolphin pod and slowed the boat to be sure everyone got a view!

Great experience!

Fun day! We enjoyed the 45 minute ride to the reef, boat was clean and comfortable, crew was friendly, and there was a bathroom on board and plenty of water available. Snorkeling was great…beautiful reef, saw lots of fish, safety information and guidance from the crew was super helpful. Note…snorkeling was off the boat in open ocean, so maybe a bit intimidating for first timers or young kids? That said, the crew did a great job of providing help, ideas and modifications to accommodate various swimming levels and snorkeling experiences. Music and fruity adult drinks were also a fun touch! Would definitely recommend!

Amazing evening and memories!

We booked the morning off because we are the type of people that like to wake up and decide what we feel like doing the day of….come early and check in at desk to sign the waiver. There are many restaurants at the marina….we arrived about 2 hrs before and had plenty of time to eat, use restrooms apply our sunscreen and look around the docks at the fish and even saw a manatee hanging out under on our the bigger boats!!! It was a windy day so waters were a bit cloudy and choppy but nobody can control Mother Nature! My daughter and I had an amazing time and were still able to see lots of beautiful fish. The time slotted at each of the 2 coral reefs was just enough for us, as this was our first time snorkeling out in the open water and we were a little nervous to venture too far from the boat. The sunset was breath taking on the boat ride back-I would recommend getting a spot to snuggle up on the top deck for the best view! They stopped the boat as we passed a family of dolphins-it wasn’t a dolphin excursion but they may as well have been paid actors!! The crew was great and very knowledgeable! The one girl also gave us the best easy chill dinner recommendations after we docked. My 15 year old daughter had the best time and was all smiles from ear to ear the rest of the night!! Thank you!!!

Amazing morning snorkelling in Key West!

Really well organized, an excellent experience! Fantastic and personable crew. Instructions and guidance were clear. Equipment was clean and the snorkel site had many colourful fish swimming around coral reefs. Captain slowed and stopped the boat on the way back to allow us to see dolphins.

Wonderful!

Wonderful! My daughter and I had a great time! Just long enough (for me)-not too long, or too short. Snorkled for an hour. May have liked to snorkle a bit longer but overall good! Had fun! Sad, though, our reefs are dead and bleached. Must do something as a whole to help them.

Misrepresented Breakfast

Nice 3 hours at sea. Boat clean staff friendly. However , it was advertised as Offering “Gormet” breakfast which it certainly was NOT. Breakfast was dry croissants (no butter or jelly etc) and sliced cantaloupe. Breakfast should be described at Continental at best. Overall good experience.

Great excursion from Key West

My husband and I did this trip on Christmas Eve and had a wonderful time. We weren't sure we would really see dolphins, but we did! Our captain diligently drove the boat around until we found a group or two in the shallows. We then went to a different area to snorkel for a bit; there were some fish but not a ton of sea life (I didn't mind, it was fun just being in the water). They provided drinks after swimming and the vibe was very laid-back and friendly. We had a great time and would recommend this trip to others!

This was a nice, clean...

This was a nice, clean and organized snorkeling trip for our family of four. We on had one stop, but we saw a lot of fish and other sea life. The trip was not very expensive and the bar was free after snorkeling. The drinks were great and not light on the alcohol. The crew was professional and friendly.
