Overview
- INAH’s Operativo Equinoccio ran March 20–22 across 45 archaeological zones in 20 states, with set hours, capped access and rules that barred pets, food, alcohol, drugs, weapons and bulky bags.
- Teotihuacan hosted thousands under a coordinated INAH–police deployment, with climbing still restricted on the Pyramid of the Sun and limited access on the Pyramid of the Moon.
- Chichén Itzá drew heavy turnout, with reports of more than 15,000 visitors over the operation and roughly 9,000 watching the Kukulcán light-and-shadow effect during the main display.
- Dzibilchaltún was added back at the last minute after an earlier exclusion, opening with incomplete maintenance, without full security barriers or emergency services, and with only about eight custodians.
- INAH estimated about 300 people witnessed the sunrise alignment at Dzibilchaltún’s Temple of the Seven Dolls after weather foiled viewing the previous day, while Cacaxtla–Xochitécatl reported hundreds and a local tourism boost.
