What a disappointment. The reefs have not sealife...this is a lot of money to Nothing. Very disappointing waste of precious time of my.guests...saw more fish waiting on the dock than at the reef
Response from Host, May 2026
Peter, sorry Nature did not meet your expectations but then we humans have not met Natures expectations of taking care of our planet! You obviously missed our message.

Response from Host, May 2026

Christine_L, Apr 2026
The boat goes out 45 min to the reef. It's hit or miss if you will see any large fish or turtles.
The boat is very stable, neat and clean. We had a beautiful day, water smooth as glass. We saw numerous sergeant majors and a few parrot fish.
Response from Host, May 2026
Thank you for taking the time review your experience with us, glad the seas were calm, sorry the King Neptune did not let to many of his creatures out for your voyage.
Audrey_H, Apr 2026
We were really looking forward to this experience, going on my birthday.
Unfortunately, the reef was very disappointing and the death of the coral
was saddening. The fish were small and sparse. For the time and money, it was really not worth it!
Response from Host, May 2026
Audrey, sorry if we did not meet your expectations, the, and that not many of King Neptunes creatures were out and about during your trip, hopefully you had a Happy Birthday!

Renee_C, Apr 2026
It was an enjoyable trip and great to see so much life under us!!! The changes in the reef structures and building of it. My sister, unfortunately, couldn't stand for the whole thing as she does get carsick/so this rocking had the same effect. But the colors on the water and all that we saw was very enjoyable and the crew was very pleasant.
Response from Host, Apr 2026
Reenee, glad to hear your group enjoyed their trip with us!

Greg_P, Apr 2026
Trips can be canceled last minute due to wind conditions. Viator, the booking agent, is not wanting to refund my money. Buyer beware.
Response from Host, Apr 2026
Greg, sorry to hear that Viator has not refunded your money if you contact the ticket counter at 305/451-4655 we can review your booking and see why the refund was not issued, as that is on Viator we requested them to refund or re-schedule our guest because of the cancelation
Susan_G, Mar 2026
Nice boat ride, very relaxing. Guide was great. A lot of interesting information was given.
The coral reef was not exciting at all. No one’s fault just nature.
Response from Host, Apr 2026
Susan,
Thank you for the nice review.
Tao_L, Mar 2026
I was notified of the cancellation of this activity due to in sufficient people participating in it on the chosen. Viator mentioned someone would contact me for refund or rescheduling. I haven't heard from them yet, this booking was not displayed as cancelled on viator either.
Response from Host, Mar 2026
Tao, the reason for our cancelation had nothing to do with insufficient people in fact just the opposite, the cancelation was due to a Small Craft Advisory that was issued for our operational area. You did not talk to Viator you talked to our Ticket Counter and we put in the refund request for you through Viator any refunds coming to you would come through Viator since that is who you paid for tickets, everything on our end is documented via computer log.

Response from Host, Mar 2026
Donna, so glad you enjoyed your trip with us aboard the Key Largo Princess!
Thomas_A, Mar 2026
Enjoyed the experience. The boat was clean and well cared for and crew were terrific. The boat has plenty of cover from the strong Keys sun on both decks. We happened to have perfect weather with mild weather and smooth seas.
Viewing of the reefs was through the hull windows was interesting. The water was very clear. Not the same as being among the corals and fish, but not bad for the money.
Response from Host, Mar 2026
Thank you for the thumbs up! Glad you had "perfect" weather for your voyage!
Hilary_R, Mar 2026

Excellent ride and knowledgeable hosts. The boat was clean and highly recommend for families wanting to explore the reef.
Response from Host, Mar 2026
Thank you for the excellent review, rating and recommendation!
ann_H, Mar 2026
If you’re prone to sea sickness, bear in mind that it’s a 45 minute trip to the reefs and it can be rocky. Also, I’m sad to say that much of the reef seems to have died. We saw a lot of dead coral. That said, the glass bottom worked well to allow us to see what there was and the staff worked hard to make customers comfortable and provided a thorough description of what we were able to see. If you’re unable to snorkel and like being on the water, this is still worth it.
Response from Host, Mar 2026
Ann, thank you for taking your time to rate and review your experience with us, glad you found it worth it!
