Dos Ojos means the one of the biggest underwater caves to be found in the world. It is a very lengthy cave system which measures about 57 km. In Spanish, the term Dos Ojos means two eyes. This is referred to one of the leading entrances that connect the two big caverns.

The water source in the cave is from rain filtered with the help of the limestones, responsible for the very clear water it renders to scuba divers or those who just intend to snorkel. The water temperature measures normally to 77 degrees all throughout the entire year.

There is also a bat cave within the connecting caverns which can be accessed through diving or snorkeling alone. With the help of some diving light, you would be able to see some bats sleeping on the roofs of the cavern.

The usual dives which take place in Dos Ojos are just a bit less than 30 feet to give way for longer time underwater. It is recommended that you do the dive with a trainer for cave diving can be really dangerous to anyone who will do it for the first time. Try one of these best cave dives you can only experience in Mexico.
