Reviews: Key West Dolphin Watch and Snorkel Tour - Eco Adventure

Guest User2026-02-06

We booked a snorkeling excursion with FURY, one of Norwegian Cruise Line’s shore excursions and the 2025 Travels Choice Award winner for Outstanding Water Adventures in the Keys. FURY has been a staple here for more than three decades, and it shows. Quick tip: You can book this excursion directly through the FURY website and save some money. However, booking through the cruise line guarantees you won’t be left behind if there’s a delay returning to port. With such limited time in Key West, the extra cost was worth it for peace of mind. Within minutes, we’re off—along with a boatload of fellow NCL passengers—aboard one of FURY’s catamarans. This is a very popular excursion. Everything you need is provided: snorkeling gear, vests, flotation noodles, and even wetsuits available for rent. FURY also has equipment for all shapes and sizes… including kids! During the 30-minute ride out to the reef, I chat with Captain Willie about the adventure ahead. Soon enough, it’s time to enter the water. Captain Willie gives us a heads-up—the water is a bit rough and cool, around 70 degrees. But we suck it up and take the plunge! We’re snorkeling over a portion of North America’s largest living reef. Visibility is pretty good, and the scenery is stunning—sea fans sway harmonically with the current, coral heads rise from the ocean floor, and marine life surrounds us. As Captain Willie explained, this is the Rock Key Sanctuary, just east of Sand Key. There’s a strictly enforced no-touch, no-take policy, helping preserve this fragile ecosystem. We’re swimming in 10 to 25 feet of water, making it perfect for all skill levels. Denise points out a yellowtail snapper swimming below us, while another species nibbles at the living coral rock. Even with nearly 100 swimmers on the reef, it somehow feels like we’re all alone—completely immersed in this tropical wonderland. The swaying sea fans are hypnotic. We give this adventure a big thumbs up as we head back to the Pacific Fury, where Captain Willie gets the party started for the ride back. It’s been 20 years since we last explored the Florida Keys coral reef, and honestly, it rivals what we’ve experienced in Hawaii and the U.S. Virgin Islands. If you’re visiting Key West, this is an absolute must-see experience

We had a great time - we saw lots of fish, sting rays, barracudas. The water was beautiful and the boat ride was fun. The drinks were great and the crew was very helpful.

Fun trip and love the salty air and splash of the waves. We had an all female crew and captain and they were wonderful! Knew their stuff about boats, the ocean, snorkeling, etc. we saw dolphins which made my trip perfect! The snorkeling was just ok; only because it had rained that day and the wind was up so water was murky and not clear. The sunset was pretty despite the clouds/rainy skies. There was a little drama between some passengers and we had to take people back to the dock and drop them off; but we went right back out and finished our adventure. Great time and trip!!

We had a wonderful day. We thought it would be a tourist trap, but it wasn't at all. An old sailboat in very good condition, incredibly friendly, helpful, and cheerful staff. A high-quality cold buffet lunch with unlimited drinks. I highly recommend this experience. Go for it, you won't be disappointed.
