Great sea life - This destination is one of the better snorkeling areas for variety and quantity of sea life. It's not far from shore so the trip there and back is just right.

Best turtle encounter ever - Captain Patrick and crew were great. Found a sea turtle 🐢 right where they said they would e. Had the best turtle encounter on this snorkel 🤿. The turtle just swam along side us just checking us out. Great visibility as well and tons of assorted fish.

The snorkeling was good… nice coral and a good mix of fish. It was a perfect amount of snorkeling… Not too long, not too short We were provided with beverages and snacks as well… Which was a nice surprise.

Great Time! Go Direct! - We had a Great Time with Captain Pips snorkel boat out to Sombrero Key. Staff Jaynell & the Captain was very good! Tropical all over, the reef looked to be in great shape! They had sodas & water before snorkeling & beer for after snorkeling. The Only Bad Aspect of this Trip. TripAdvisor / Viator charged $100.00 more than if you had gone through Captain Pips directly.

It was fine. We would probably not do this one again but again we are just a couple. Better for groups saving money - It was fun. Definitely a no frills snorkeling trip. Great if you have a big group. The captain and first mate were very pleasant and capable.
