That's a good question. If you wanted to choose the most beautiful cenote, you would really have to make a difficult decision. All of them are rather unique in their own way and somehow magical. Therefore, I can only recommend you to visit several of them. Then you will quickly find out which one is the most beautiful cenote for you. Most cenotes are located in the Mexican state of Quintana Roo along the Caribbean coastline. There are thousands of them along the coast from Cancún down to Bacalar in the far south. But also, near the Gulf Coast in the neighboring State of Yucatan there are countless of these wonderful accesses to the underground rivers. There they are arranged rather in a ring around a huge crater left by the impact of a meteorite in the Gulf of Mexico over 60 million years ago. This catastrophe was probably also the reason for the formation of the extensive underground rivers.
