Diving the Cenotes in Mexico.

The soil in the north of the Mexican peninsula of Yucatan consists of limestone. Characteristic of these soils is the fact that it is very porous. The soil can not hold the rainwater. For centuries long rainwater seeped through the porous limestone. In this way underground tunnels and caves with stalactites arose. When the seawater rised these caves were flooded. We all know the feeling of walking into a cave. But float between the stalactites is truly an experience you do not want to miss.
