Cenotes The Sacred Waters of the Riviera Maya is a fresh water dive site, located in Mexico.
The natural wonders of the Yucatan Peninsula are countless, but some of the most unique to the area are the cenotes. Cenotes are created by an underground river system and are fresh water sink holes that the Maya considered to be sacred. In addition they were an incredibly important resource as a fresh water source, and the Mayans also believed they were the entrance to the underworld. Cenote, (say-NOH-tay) called dzonot (ZO-note) by the ancient Maya were defined by the Motul dictionary, a dictionary of Mayan hieroglyphics, as "abysmal and deep" or "hole filled with water".
Millions of years ago, the Yucatan Peninsula was covered by the ocean. Some 15,000 years ago, during the last Ice Age, the sea level descended approximately 250 feet.
For thousands of years, the porous land surface, formed by fossilized coral and limestone, has filtered rainwater, which dissolved parts of the subsoil. This process created a system formed by flooded underground rivers and caves. This phenomenon is truly unique, and makes up the largest network of caverns in the world.
Cenotes are formed when the roof of a cavern collapses due to erosion. The level of the water also contributes to the creation of cenotes: if it is too low, it does not provide enough support, which causes the roof to weaken and cave in.
The depth of each cenote depends of the amount of natural debris that has accumulated through erosion in addition to the remains of the roof that collapsed. The water that gathers in these amazing natural wonders is a crystal clear turquoise color with a very pleasant temperature of 78°.
The stalactites and stalagmites that form inside the cenotes are true natural works of art. In many, holes in the ceiling allow the sunlight to filter into the cenotes, giving the scene a magical feeling. The cenotes of the Yucatan Peninsula are a true natural gift that should be seen by all, but keep in mind that they should be protected so that they are here for generations to come. You can do your part in local conservation by not using any lotions, sunscreens, perfumes, or repellents prior to swimming in a cenote. Many cenotes provide showers that you can use to rinse off before going in.
There are four different types of cenotes - those that are completely underground, those that are semi-underground, those that are at land level like a lake or pond, and those that are open wells. Some of them are accessible for swimming and cave diving, some of them are not accessible at all, and some are actually dry cave systems that can be explored.
Sizes and shapes of the cenotes differ according to their location. Some cenotes have been found to hold quantities of ancient offerings and jewelry, apparently thrown in the depths by the Mayas who once inhabited the area.
Currently, an estimated six thousand cenotes have been found in the Mexican states of Yucatan and Quintana Roo. In the Riviera Maya, many cenotes have become famous, for their individual features offer different types of amusement for their visitors.
And remember..."take only memories and pictures leave only bubbles"
In most cases, cenotes offer basic facilities such as bathrooms, dressing rooms and parking. Entrance can run anywhere from free to 100.00 pesos depending on where you go.
