Cenotes, ultimately, became the only water source for the Mayan civilization. Thus, the people consider them sacred spots. Perhaps the most prominent cenote in the region is the Cenote Dos Ojos (two eyes). It earned its named because of the two rivers that unite in a big underwater cavern. Dos Ojos is also very famous because it is, at the moment, the deepest known cave passage in the Yucatan. It is estimated to be more than 415 meters deep.
This cenote lies 13 kilometers north of the town of Tulum, juts a kilometer south of Xel Ha. The dirt road, which stretches 4 kilometers, off Highway 307 leads to the entrance of the cenote. This journey is an adventure in itself as you may most likely come across some interesting flora and fauna along the way. There are two hardwood decks that are set up at the entrance that serve each river. The left side (eye) is usually where the divers enter, while the right side is where more swimmers and snorkelers go.
Cenote Dos Ojos dazzles visitors with its large cave system, which features large columns and clear water. There are many ways to explore Dos Ojos; the first one being scuba diving. By doing so, you will be able to marvel at the deep cave walls up close. With miles and miles of extensive cave systems that connect to more than 25 cenotes, you have a lot of freedom of which direction to dive through. Take note that you need an open water diving certification to be allowed to dive.
If you don’t have the needed certification, you can always to snorkel, which is also fun. There are even tourists who just swim or look around the cenote. If you intend to snorkel, climb down the stairs from the right entrance or second eye. From here, you can explore the secret passageways made of stalagmites and stalactites. The passages can bring you different caves. One of them is called the Bat Cave, which is part of the cave system called Hidden Worlds.
Cenote Dos Ojos receives the same water that flows into the large Caribbean cove called Xel Ha. This water is believed to have healing powers and is considered very pure as it comes from a massive area pristine jungle. To protect the pureness of the water, divers and snorkelers are highly discouraged to not use sun tan lotion, which may pollute the water.
