Chichén Itzá Ramps Up Security for Spring Equinox Event

Chichén Itzá, Yucatán — The iconic Chichén Itzá archaeological site in Yucatán will open its doors for visitors to experience the 2026 spring equinox, which officially occurs on Friday, March 20 at 8:46 a.m.

The National Institute of Anthropology and History (INAH) said the traditional contrast of light and shadow projected on the staircase of the Templo de Kukulcán will also be visible on days near the equinox. The special operation aims to protect this UNESCO World Heritage site and ensure a safe experience for attendees.

To maintain order and security, the event will involve coordination between state and federal authorities, including police, civil protection, the Red Cross, and university students. Opening and closing times will vary: on March 20, the site opens at 9:00 a.m. with evacuation at 5:30 p.m., while on March 21 and 22, it opens at 8:00 a.m. with evacuation at 5:30 p.m.

INAH reminded visitors that access to restricted areas, ceremonies, and drone flights are prohibited. Professional photography or video equipment requires prior authorization.

The spectacle involves the projection of seven triangles of light and shadow on the northern staircase of the Templo de Kukulcán. When these align with the serpent head sculpture at the base, it creates the illusion of the serpent descending the pyramid between 3:00 p.m. and 5:00 p.m.

The Gran Museo de Chichén Itzá will remain open from 8:00 a.m. to 3:00 p.m., with access via the Cenote Sagrado area and re-entry permitted. Admission costs 105 pesos plus an additional state fee; on Sunday, March 22, entry will be free for national visitors, indigenous communities, and resident foreigners.

Due to expected high crowds, authorities recommend considering visits to other nearby archaeological sites like Izamal, Ek’ Balam, Uxmal, and Kabah for a more tranquil experience.

In September 2025, approximately 6,500 people gathered to witness the descent of Kukulcán during the autumn equinox at Chichén Itzá. A brief break in the afternoon drizzle allowed the feathered serpent shadow to appear on the pyramid at 4:51 p.m., amid cheers and awe from the crowd.
