In the north and northwest of the [[Yucatán Peninsula]] in Mexico, the cenotes generally overlie vertical voids penetrating {{convert|50|to|100|m|abbr=on}} below the modern water table. However, very few of these cenotes appear to be connected with horizontally extensive underground river systems, with water flow through them being more likely dominated by aquifer matrix and fracture flows.<ref name="Beddows, P.A. 2003"/>

In contrast, the cenotes along the Caribbean coast of the Yucatán Peninsula (within the state of [[Quintana Roo]]) often provide access to extensive underwater cave systems, such as [[Sistema Ox Bel Ha]], [[Sistema Sac Actun]]/[[Sistema Nohoch Nah Chich]] and [[Sistema Dos Ojos]].
