The name 'Zaci' is derived from the ancient Mayan city that once stood where modern-day Valladolid exists today.
The sinkhole's water level is influenced by the surrounding karst landscape and regional rainfall patterns.
The cenote is technically classified as an open cenote, as the original roof collapsed long ago, exposing the water to sunlight.
It is one of the few urban cenotes in the Yucatan Peninsula located directly within a city center grid.
The high rock walls surrounding the water create a distinct micro-climate that supports shade-loving tropical plants.
Cenote Zaci is an open-air semi-subterranean sinkhole located in the heart of Valladolid, Yucatán. It measures approximately 45 meters in diameter and reaches depths of up to 100 meters. The cenote is fed by underground rivers and features a high ceiling with stalactites and hanging vegetation. A walking path encircles the perimeter, allowing visitors to view the water from various elevations. The site is managed by local authorities and serves as a public swimming spot for residents and tourists. Its central location makes it the most accessible cenote in the city. The water often contains freshwater fish, including black mollies, which are visible from the surface.
The upper observation deck provides a panoramic view of the entire sinkhole and the hanging vegetation.
Bring biodegradable sunscreen if you plan to swim, as standard chemical products are prohibited to protect the water quality.
Wear water shoes for better traction on the slippery, moss-covered stone stairs.
Bring a waterproof pouch for your phone or camera to protect equipment from humidity and accidental drops.
Do not leave personal belongings unattended on the rocks; avoid feeding the fish.
Shower before entering the water; avoid using soap, lotions, or hair products; no jumping from the highest cliff edges.
