Security tightens at Teotihuacan

Mexico has doubled security at Teotihuacan and other INAH-run archaeological sites after a gunman killed one Canadian tourist and injured about 13 others at the Pyramid of the Moon on April 20. The site reopened on April 22 with metal detectors, bag checks, stronger National Guard and auxiliary police presence and more surveillance. Officials said the measures are staying in place.

Security Secretary Omar García Harfuch said the response began immediately after the shooting, which happened in daylight before the attacker was confronted by National Guard officers, wounded and died by suicide. INAH director Joel Omar Vázquez Herrera said the tighter controls are meant to protect visitors without shutting people out.

What nomads and visitors should expect

The changes apply to tourists, day-trippers from Mexico City and expats planning visits to sites such as Teotihuacan, Chichén Itzá, Monte Albán, Tulum and Mitla. By April 27, five metal detectors had already been installed at entrances and authorities say the checks will remain at INAH sites nationwide.

Lines are likely to move slower. Visitors should expect ID checks, ticket verification, bag inspections and screening for large bags, weapons, sharp objects and drones. Officials have told people to arrive early.

How to plan a visit now

Build in extra time before you go, especially for popular sites near the capital. Bring a valid ID and your ticket proof and keep bags small to avoid delays at the gate. There’s no new fee, but there are now more steps before entry.

The tighter controls are tied to broader security planning ahead of the 2026 FIFA World Cup, with authorities preparing for millions of visitors. Read our full Mexico guide for the complete picture and keep up with visa updates for more travel-alert coverage.
