The limestone bedrock of Quintana Roo, Mexico, conceals a labyrinth of subterranean wonders: the Tulum cenotes. These sinkholes, portals to the Mayan underworld, Xibalba, are more than just scenic pools; they are geological and cultural archives. The complex hydrology of Sac Actun, one of the world’s longest underwater cave systems, exemplifies the region’s unique karst topography. Unlike surface rivers, these cenotes in Tulum are fed by rainwater percolating through porous limestone, creating intricate networks of underground rivers. The Maya, deeply connected to their environment, saw these Cenotes as sacred gateways, reflecting their understanding of the cyclical nature of life and death. Today, these natural springs, or cenote systems, draw researchers and tourists alike, offering a glimpse into both the Earth’s history and the rich cultural heritage of the Maya. Furthermore, the natural springs of the cenotes Tulum are a natural wonder.
