Reviews: Key West Afternoon Reef Snorkeling with Open Bar

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.

Reviews: Key West Dolphin and Snorkel Experience

Guest User2024-07-13

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!!
