Our Guide to the best Cenotes around Tulum

Updated: Jul 7

All cenotes are unique and there are no two alike. Exploring these underground waterways and snorkeling in cenotes is a magical experience that you can experience only in the Yucatan Peninsula. There is an endless variety of size, form and depth, including open, semi-open and closed cenotes, numbering in total more than 10,000 registered in the region. You would need a lifetime to visit them all! No worries, we have put together a selection of our favorite cenotes near Tulum so you don’t have to explore all of them yourself. But first, a little background information…

How are the cenotes formed?

A Cenote is a freshwater sinkhole where you can swim, snorkel or scuba dive and observe amazing rock formations, limestone passageways, stalactites, stalagmites and columns, as well as tropical vegetation and many different species of wildlife.

According to the experts, the formation of cenotes began some 65 million years ago, when the impact of a meteorite created cracks, cavities and fractures in the Earth’s surface.

At the time, the Yucatan peninsula was submerged under a shallow sea and formed part of an immense coral reef that also included parts of Florida and Cuba. Hence the similarity in geography between some parts of the Yucatan and Florida peninsulas.

Over the passage of time, the shifting structure of the Earth’s surface, periodic climate change and the rising and falling of sea levels exposed this prehistoric coral to the sun and air. This in turn caused the breakdown of the reef into sediment, and over further millenia the sediment of the ocean into Limestone (Karstic stone), leaving us today with the giant limestone platform that we call the Yucatan Peninsula.

The formation of the cenotes themselves occurs because rainwater has a degree of acidity due to trapped gas, mostly carbon dioxide. This CO2 (dissolved in water) then mixes with organic elements in the soil & vegetation when it hits the ground. Limestone or karst is extremely permeable, which means that the rainwater filters through the rock very easily. As filtration occurs, the acidic element of the rainwater (called carbonic acid) reacts with the limestone, causing it to dissolve. This process is called dissolution.

Little by little the process digs away at the rock, eventually causing the collapse of a section and opening up a hole in the ground, and voila, a cenote is formed. These natural skylights allow sunlight to penetrate further down and help vegetation grow, in some cases creating an atmosphere of a tropical jungle oasis or a ‘land before time’.

Of course, because underground rivers flow through and underneath the Karst platform, these cenotes become the access points to flooded cave systems - now a Mecca for cave divers from all over the world who explore these waterways to look for connections and map the systems. Due to the fact that the caves have endless forms and shapes because of erosion, dissolution and changes in sea level and water currents, we are left with the huge variety & uniqueness of cenotes that you can visit today in the Yucatan.

Today the cenotes are places of relaxation & exploration, where families and visitors from all over come to swim and refresh themselves in a natural, freshwater swimming pool, or explore the flooded caves associated with them. During the Mayan era, they were considered sacred places, representing the entrance to the underworld and a connection to the ancient source of life.

Cenotes need to be protected

For all of us, then as now, the cenotes & underground rivers are the most important source of freshwater and the protection of them from pollution is absolutely critical to the wellbeing of the region.

In order to preserve these incredible ecosystems, all chemical products are forbidden such as sunscreen, anti-mosquito, cosmetics... It is important to know that any contamination of the cenotes goes directly to the coral reef, which is a marine ecosystem that is already very fragile. Their use pollutes enormously leaving a layer of fat on the surface of the water and all forms of aquatic life die (fish and vegetation). That's why, in order for everyone to participate in the conservation of these healthy and natural spaces, we recommend wearing long-sleeved t-shirts to protect yourself from mosquitoes and the sun. And don't forget that the passage in the showers is mandatory to avoid any contamination.
