Make your own way to the meeting location to join your guide and group. Suit up in a life jacket and snorkel equipment, and then head out on a 2-person speedboat for a ride around Nichupte Lagoon. Decide whether you want to drive the boat or just ride as a passenger. Either way, listen to your guide talk about the mangrove forest and the diverse wildlife it protects—you might even catch sight of a seabird or crocodile.
Then, don your snorkel equipment for a dive down to the Mayan Coral Reef at Punta Nizuc, which is home to fish and wildlife, as well as a collection of underwater statues. After snorkeling, head back to lagoon before entering Cancun Bay.
Your tour concludes near the original departure point.
