Super fun and friendly crew. We went out on a perfect morning, so the boat ride was smooth for those prone to getting seasick. Fish were everywhere! Crystal clear, warm water and nothing but tropical fish. Very cool!
Fun time! Saw lots of beautiful fish that I’d never seen before…parrot fish were my favorite. Also saw barracuda, Stingray, sea turtle, tons of seaside & beautiful reef
Great tour! Very choppy waters when we went out, but David and Orion were awesome. Very safe and fun trip. The lighthouse is cool to see. The reef and sea life was wonderful.
Our adventure started on a gorgeous day and the booking, location and staff were awesome! We arrived at the reef well instructed with all the necessary gear provided along with snacks and beverages. The reef was calm and clear at arrival and the marine life was plentiful. Fantastic sightings of barracudas, tarpons, grouper and more to numerous to name. One guide even dove down and brought up a large conch to show us! Well worth every penny!!
We love snorkeling at Sombrero Key Lighthouse. There are always so many beautiful fish! Captain Kinsey and Mate Orion were friendly and helpful. The ride to the reef and back was smooth and enjoyable.
Amazing experience. The captain and first mate were so great, everything went so smooth from the check in to the snorkeling to the return. Highly recommend and I will be back
The Skipper Kerry anchored in the perfect spot and got the schools of fish going before we hopped in. The group saw anything from Yellowtail Snapper and Parrotfish up to a small Nurse shark and a couple Barracuda. Great snorkeling!
Awesome experience!! They provide everything you need. Captain Kenzie & Orion were great & super helpful.
Thank you for joining us! We're glad to hear you had an awesome time. Come see us again soon!
Had a great time. The snorkeling was excellent, very clear waters and lots to see. We did snorkeling off Key West the day before and it was nothing compared to this. If you are looking for great snorkeling, this is the place to do it. The boat and crew were great, super helpful and fun.
We're so glad you got to experience the Reef with us. Thank you for the awesome review. Be sure to come see again soon.
We booked Sombrero Reef in July. When we arrived to the meeting point, we were told that the water was too choppy today so we were not going to Sombrero Reef. We were going to Pirates Cove instead. We were given a few minutes to decide if we wanted to cancel. In that short window, I had no idea if I'd be able to book Sombrero Reef for the one remaining full day of our trip so we opted to go to Pirates Cove. It was a huge disappointment. Saw nothing! A few schools of guppies was about it. This ruined the vacation for my teenagers as that excursion was the highlight that they were looking forward to. My husband and I are boaters and really could not understand why the captain thought the water was choppy. There were no weather events happening. There was only one other boat at Pirates Cove that day so I imagine all the other tours went to Sombrero Reef. If this happens to you, opt out! DO NOT GO TO PIRATES COVE! Totally underwhelming experience. The crew provided canned soda, chips and water for your refillable water bottles. There was no fruit provided.
Thank you for taking the time to leave your feedback. We would like the chance to address a few things. The date of your trip it was calling for 3ft seas at the reef. This is terrible and unsafe conditions for snorkeling. We gave you the option to rebook, get refunded, or join us at an alternate location. On days like this we do everything we can to communicate clearly with our guests and give them every available option. We explained what this alternate location would entail and even brought out paddle boards, kayaks, and water toys to enjoy. To leave us a bad review seems unfair as we cannot control Mother Nature. We hope you will give us another opportunity next time you are in the Keys to give you a safe and enjoyable snorkel trip out to the reef.
