The Rio Secreto is one of the newest cenotes located in the Mayan Riviera, Mexico. A distinct and incredible natural reserve, the Rio Secreto is the longest semi-sunken cave system in Yucatan. The underground caves, unlike many other cenotes, do not require any diving certification, as one can simply walk or float through the 12-km stretch of caves and explore the limestone caves and passages with enormous stalactites hanging overhead.
