What does cenote mean?

A cenote is a natural sinkhole or well that exposes groundwater beneath the Earth's surface, primarily found in Mexico's Yucatán Peninsula. These geological formations are often filled with fresh water and are formed by the collapse of limestone bedrock, creating a unique ecosystem. Cenotes are not only important for biodiversity but also historically significant as they were used by ancient Mayans for water supply and religious rituals. Today, they are popular tourist destinations for swimming and snorkeling.
