Great opportunity to discover this amazing and fragile hydrological ecosystem full of wonders. We start our journey exploring an open mangrove cenote part of the longest underground river system of the Yucatan Peninsula, where it is possible to witness incredible diversity and to understand the complexity of this wetland ecosystem. We continue our water experience with a visit to the Mesoamerican Coral Barrier Reef where we discover the marine behavior surrounded by a wide variety of amazing coral formations and a big diversity of colorful fish. We finish our day snorkeling in a cave cenote. A magical world where we can see the delicate rock formations that are the result of the deposit of minerals hauled through the porous stones: stalactites and stalagmites. A delicious Mexican meal is shared to finish our water experience.
