Great Trip - But Bring Your Own Snorkel! - This trip was great! The boat ride to the reef is about 40 minutes through beautiful waters. Then you snorkel for 45 mins or so, then head back. The reef was a great place to see all kinds of fish - we saw eel, crab, lots of colorful fish, and even a nurse shark! Life vests and pool noodles are provided, which helps newer snorkelers stay afloat. NOTE -- the snorkel itself is NOT included, just the mask and flippers. So bring your own snorkel to avoid overpaying the tour company for one. (You do keep the one you buy, but without a mask, it's kind of useless...). Also recommend medication for motion sickness if you are prone to that. The waves you're swimming through can bring that on, especially if you are on an empty stomach. (You can bring your own snacks and drinks on the boat.)

Awesome experience! - Very well organized. From start to finish. All of the staff and Boat captains are amazing. Highly recommend. I also enjoy the fact that it was a great amount of time. Some of the other snorkel trips are much longer. That’s great if that’s what you enjoy, but this is a great opportunity to fit an activity in your day, but not take up the whole day.

Key Largo snorkeling - We checked in at the snorkeling office. Bought snorkels, ($15.00). Fins and mask are provided with tickets. We also rented wet suits for $10 each. Note, you can bring your own snorkel.
We arrived an hour prior to boat ride to get our wet suits fitted and get to the dock from the main check-in. We’re glad we allowed enough time for bathroom break prior to donning wet suits.
Staff was great. They made directions clear, maintained a safe and fun boat ride out to the reef, explained safe snorkeling techniques. It was a bit choppy on the water, but they explained to keep head in the water and don’t fight the waves. It was wonderful and I saw an octopus along with hundreds of amazing fish and coral and sponges. Great fun.

Incredible trip! - What a perfect day! The snorkeling was amazing and the crew was friendly and helpful. Carolyn and Justice were so informational and helpful. We always felt safe and the variety of fish and coral we saw was incredible! My camera acted up, so we didn't get any photos, but if you can, bring a waterproof camera on this trip. A definite highlight of our vacation and great for all ages.
