The Experience

The boat leaves the northern shores of Cozumel with a transparent hull that lets you watch the seafloor pass beneath you—sunken ships, coral formations, and fish moving through the water, all without leaving the deck. The guide narrates what's below as the boat glides across clear Caribbean water, and you stay dry the entire time. This first half sets up what comes next: you've already seen the reef, so when you slip into the water at Legos Reef, you know what to look for.

The snorkeling happens at Legos Reef on Cozumel's southern side, where you spend 15 minutes in the water surrounded by living coral and schools of tropical fish. The certified guide stays with the group, and snorkeling equipment is provided—you bring only your comfort in the water. Lifejackets are available for anyone who wants one. The reef itself does the work; you float above it and watch.

The whole tour runs 90 minutes from start to finish. You get a complimentary drink—either bottled water or a soft drink—and the boat returns you to where you started. Children from age 1 can join; infants sit on an adult's lap during the boat portion. Pregnant travelers are not eligible to participate.
