- Must-see highlights: The cenote is a natural sinkhole formed by collapsed limestone. They were critical to providing a source of freshwater to the Maya. Their crystal clear waters are a sight to behold.
- Current use: The cenote is not used in any way today, but serves as a critical reminder of the importance of water to the Maya, along with its role as a site for rituals, sacrifice, and a portal to the underworld.
- Unique facts: Besides retrieving pottery, jade, and jewellery, Spanish chroniclers reported rituals in which maidens and captives were cast into the waters as offerings to Chaac, the rain god.
