5.00Such a great trip! I would highly recommend the company. Our captain and crew were fantastic. So friendly, super helpful and kept us safe at all time. If you enjoy snorkeling or are just looking for a new adventure, this trip it’s a must.
Fun trip

4.00Fun trip, wish the waves weren’t so choppy but we won’t fault the venue for that lol. Engine was a little loud so don’t sit near the back. Three miles out with two roaring diesel engines in the back is not kind to the ears.
Amazing!

5.00Cpt Rick handled the boat really well given not so great weather conditions. Liber and Justus were great and very helpful with the tour and what to expect. Great food recs for the area too!!! Y’all salvaged our spring break after multiple weather cancellations ❤️ plenty of fish and even a shark that I initially don’t want to see 😬
We had a great time!

5.00I went with my 19 & 22 year old sons. Captain Rick and mates Justus & Liber were awesome! The water was definitely more rough than usual but it was still amazing! We still saw lots of fish, barracudas, and even a reef shark. One of my sons said it was one of his top 3 best life experiences!
Very poor experience.

1.00Booked a trip through TripAdvisor for 2 people, $75 pp. The confirmation notice we received had little to no detail whatsoever. Showed up at the snorkel location and nobody was there. Received a call from the business who said we were supposed to show up at their office. They then suggested we move the booking to another day (2 days later). We agreed. That day showed up and they cancelled the trip due to wind and then said no refund since we "missed our original day."
A great experience ...

5.00We enjoyed our snorkeling adventure on the Sundiver III with Joe as our captain and Liber and Manuel (I think)! They were very efficient getting us out to the reef, disseminating the masks and fins. This excursion requires you purchase your own snorkel for $15, which we didn’t mind, but that could be a cost factor for others. I was also able to rent a short wetsuit which was worth the additional $10 for me. The water temp was around 70 degrees and I would have never made it in the water for as long as I did without it. We did have a great experience with Sun Diver.
Windy day - still a success

5.00Mother Nature was feeling a bit crabby and gave us some very windy/cloudy weather. Despite the potential setback, Capt Rick, Liber and Justus made the snorkeling trip so much fun. They planned a shallow and protected reef so we could still see the beauty of John Pennekamp. They were attentive, kind and engaged with the passengers paying special attention to an elderly lady who was along for the ride to share in her family’s fun. Super impressed with this charter and crew!
Best part of our trip

5.00The crew Rick Brandon and Liber were very friendly. They gave great instructions and were very patient. We had an amazing time! Saw tons of fish including puffers, parrot fish, a great barracuda that kept to itself and more. We saw 3 dolphin on the way out. We went on a wavy day 1’ to maybe 2’ rollers and the kids loved it. I highly recommend this crew!
