One and a half hours from Merida you can visit 3 or 5 cenotes, where you can swim with your family making this a fun and nature experience.
The karst soil of the Yucatan Peninsula, with the help of the meteorite that crashed the earth, in the Gulf of Mexico, killing the dinosaurs 65 million years ago, plus the help made by the erosion of the rain and the sea during All these thousands of years in the ice age, they washed all the sand under the peninsula, which was expelled to the sea leaving only a top layer of limestone, all that activity on the ground created more than 3,000 cenotes, all Connected to each other with caves and grottos flooded with the very clean water from the rain filtered by that layer of limestone, they create a huge lake (the largest in the world) but underground.
From the cenotes, which are also called sink hols (wells where you can sink, due to the low density of the water if you stops swimming one tends to sink) we can access that huge lake or aquifer where you and your family can have a refreshing swim.
