Hidden Worlds Cenotes Park
(http://www.hiddenworlds.com). offering unique jungle adventures to suit everyone, hidden worlds is situated on the most extensive system of underwater caves and caverns on earth. the park is home to some of the most incredible cenotes on the yucatan peninsula, as featured in the critically acclaimed 2001 imax movie journey into amazing caves and the 2007 bbc planet earth series.
If staying for more than just a couple of days, you may want to experience taking some Spanish lessons at the beach or at the Spanish school.
Cenotes
Casa Cenote
In tankah iii bay is a magic spot. here the cenote goes underground some 100 yards before the beach, only to emerge as an 'underwater' water spring about 20 yards of the beach, right in the ocean. must see. tanka iii bay is just over 7 kilometers 5 miles north of the intersection to the ruins. take a cab. great places to eat and stay or scuba too.
El Gran Cenote
Admission: 80 pesos.
In much of the Yucatan, rainwater collects in a system of underground caves and tunnels. Where these tunnels reach the surface is known as a cenote pronounced seh-NOH-teh. Cenotes usually allow swimming and diving, and rent related equipment. They are fresh water and are often quite cold.
