We had a great time on the excursion to the Key Largo Coral Reef. To be able to view everything up close in such a way, was just amazing. The Captain, guide, and the rest of the staff were great! I highly recommend the tour for you and your family.

Fun but short
Dean_J, Apr 2024
The boat and the ride were fun but the trip is too short in duration. 45 minute boat run each way only leaves 30 minutes over the reef for a 2 hour excursion. It seems that we had just arrived when they turned around and we headed back to the dock .It should be lengthened to spend more time over the reef. Staff was great.
Response from Host, Apr 2024
Dean thank you for the rating on a beautiful day 30 minutes over the Reef can seem too short but on a rougher day it can seem too long.
The ride was fast and fun...
Austin_G, Apr 2024
The ride was fast and fun to get to the reef. Views were incredible and got to see so many things I've wanted to but been too afraid to go underwater for. Would go again in a heartbeat! Great for family of all ages!

Austin, thank you for the fast 5 star rating, hopefully we will see you again soon!

Frozen drinks and excellent staff! Big boat with big views! Would go back in a heartbeat. We had a blast!
Response from Host, Apr 2024

Had a great time. Not all...
Chris_K, Apr 2024
Had a great time. Not all in my family feel comfortable snorkeling and this offered them a way to still see a reef and all of its wildlife. The 45 minute trip to the reef was relaxing. We decided to stay below deck (where the large glass bottom windows are) for the first part of the return trip after leaving the reef, and it was great because that was actually when we saw a sea turtle and a few rays!
Response from Host, Apr 2024
Chris, thank you for the great rating and review, the great thing about a glass bottom boat is the whole family can do it! Glad to hear yours enjoyed our trip!
Great time on the boat
Alex_M, Apr 2024
It was such a fun time. No one got sick and kids had a great time. Highly recommend to go with the family if u don’t want to go snorkeling
Response from Host, Apr 2024
Alex, thank you for the great rating and review, and what a bonus with the recommendation!
OK bit there's better!
Jeffrey_R, Mar 2024
The staff wasn't as friendly as they could have been. They seem to have had enough with tourists. The boat ride was fun despite the boat needing some obvious repairs. The glass bottom boat was OK but it was not exactly as advertised. There was only glass on the bottom , not the windows. The windows actually were very dirty ad in need of basic cleaning.
Response from Host, Mar 2024
Thank you for taking the time to rate your experience with us the window on the cabin sides have been etched over with over 20 years exposure to the salt air and sea we are investigating affordable options to correct the problem, it is more that an issue of "basic cleaning"
Fun Boat Trip
Hash_G, Mar 2024
The crew were fantastic and very knowledgeable, it's such a shame marine life was non existent and the coral was not very colourful but was a good morning out and met some interesting people.
Response from Host, Mar 2024
Hash, thank you for the fantastic rating and review
Skip it

Ronald_H, Mar 2024

Ronald, thank you for the perfect five star review.
Rough waters ruined boat ride
Susan_H, Mar 2024
The ride started out enjoyably and was too rough when we got out by the coral reefs. This is not a good trip if the weather is rough. Quite a few people were affected with motion sickness on this trip.
Response from Host, Mar 2024
Susan, thanks for the rating, sorry if the Atlantic Ocean lumpy during your trip.
Good buy needs warning
pamsell68, Mar 2024
It was good, but I think they really need to warn people about the seasickness. I saw a lot of older people who were having trouble and it didn’t hit us till the day after. And we had just been on a cruise ship for a week. I don’t think people have much fun. It probably ruins the rest of their vacation if they get sick.
Response from Host, Mar 2024
Pam thanks for the rating if you got sick the next day I doubt it as seasickness, but we do warn people during the pre-boarding announcement, again during the departure announcement.
Enjoyed the trip
Holly_M, Mar 2024
Very nice and informative trip. Saw some fish and a turtle but I know what you see can vary. Boat very clean and comfortable.
Response from Host, Mar 2024

Wonderful Boat Trip
Lagena_M, Mar 2024
My favorite parts of the trip were seeing the turtle and enjoying riding back on the top deck. The weather was so gorgeous, and the water’s blue colors were captivating.
Response from Host, Mar 2024

Good times
Mitch_T, Mar 2024
Time at the reef was a little short. Very informational. Lots to see. Tons of fish. Reef looked bit rough (curse you climate change!)
Response from Host, Mar 2024
Mitch thank you taking the time to review our trip, on a calm day 30 minutes is to short but on a rough day its too long......
Diya_G, Mar 2024
It was a wonderful experience seeing the Molasses Reef through the glass bottom. Very helpful crew ensured everyone’s safety and comfort and provided valuable context.
Response from Host, Mar 2024
Diya, thank you for the high marks, glad you enjoyed your experience with us!
Never happened
Eric_B, Mar 2024
None. This booking was cancelled the day before the trip was supposed to take place. Now they keep harassing me to write a review and write more
Response from Host, Mar 2024
Eric, sorry we were unable to provide the tour, and sorry that "they" keep" harassing you.
Loved seeing the reef
Robin_S, Mar 2024
Great way to spend the afternoon. 45 minute ride to the reef. Once there, we got to see turtles, a shark, lots of fish and coral all while being educated on the reef and its inhabitants by Jeff and EJ (who were great). Lived sitting and watching the reef beneath my feet.
Response from Host, Mar 2024
Robin, thank you for the 5 star rating, I'm glad to hear King Neptunes creatures were out and about during your voyage!
