Reviews: Half-Day Trip from Key West with Kayaking, Snorkeling & Sunset

Went on a sailboat cruise with snorkeling and kayaking. Tyler was our tour guide for both of those activities, and he was excellent. He told us so much about Key west history. Bosa was the captain, and he took us to the most beautiful areas for the activities and for the sunset. I would recommend each of them to anyone.

Good value for the money. Pretty cheap, good boat, good equipment, great guides Caiti and Liber. Reef is worth to see, I have seen many.
