The next leg in Mexico brings us to the mainland, Puerto Aventuras. The marina is a kind of Disneyland for adults with motorboats. From here we explore the depths of the jungle, the cenotes and our consciousness. Before continuing on to Guatemala, diving at Isla Cozumel is on the agenda. The island is world famous for its breathtaking drift dives with perfect visibility. So we take our new friends from Ekumal with us on the crossing and spend a day in front of el cielo at the southwest tip of the island.
