After meeting at the dive store, you will depart to explore the Sian Kaan Biosphere Reserve, which has some amazing lagoons and canals just waiting for you to explore. The beautiful lagoons are connected between various canals, which you will also be free to explore. You can follow a Mayan commerce route from an ancient Mayan city (Muyil Ruins) to a jungle path, and then ride a boat to the lagoons and canals. Later, jump in to the turquoise water and float on your life jacket along the current of a canal. On the way back you will stop in Cenote Escondido for a snack, and can also enjoy some snorkeling and swimming in the nearby pristine waters.
