Is Mexico Safe? Health and Safety Advice for Travellers
“Is Mexico safe?” is the wrong question, or at least too broad a one. Government warnings here are written state by state and sometimes road by road, and two towns a few hours apart can sit on opposite sides of a warning line.
The main tourist destinations, including Mexico City, Cancún, the Riviera Maya, Los Cabos, Oaxaca City and Mérida, are not on the UK or Canadian avoid-travel lists. That does not make them risk-free. Crime, including violent crime, still happens in resort areas. The sensible approach is to check your exact route against official advice, and then take the ordinary precautions below.
Safety Advice for Popular Destinations
The table compares two of the clearest official sources, updated in October 2026. The United States also publishes state-by-state advice, listing Mexico overall at Level 2, Exercise Increased Caution, on an advisory dated 29 May 2026. Americans should read that page directly.
Status under UK Foreign Office and Government of Canada advice, as updated on 20 and 19 October 2026. Advice can change at any time.

Where the UK and Canada Disagree
Official advice is more useful when you notice where it differs. These are the cases that could change a travel plan, and if you are from either country, the insurance consequences may depend on your own government's wording.
Differences between the two sets of advice.

| Place | UK | Canada |
|---|---|---|
| Tijuana and Tecate | Avoid all but essential travel, with exceptions for the airport, the Cross Border Xpress and certain toll roads | Baja California is not on the regional list |

| Zacatecas city | Whole state on the list | City excluded |
| Monterrey and Nuevo León | State not listed | State listed, excluding Monterrey |
| Sonora | State not listed | Listed, excluding Hermosillo, Guaymas and San Carlos, and Puerto Peñasco |
| Guanajuato state | Areas south-west of road 45D | Areas south of and including highways 43D and 45D |
San Miguel de Allende and the city of Guanajuato lie north of the highway in question, but the road you take to get there matters. The UK also warns that travelling against its advice can invalidate your insurance.

Safety Advice Sources
Facts were checked on 8 November 2026 against UK Foreign Office (updated 20 October 2026) and Government of Canada (updated 19 October 2026), and CDC traveller health guidance (reviewed 3 September 2026). Hurricane dates are from the US National Hurricane Center. We could not open the state-by-state text of the US advisory when checking this page, so the US overall level is included but its state levels are not. “No avoid-travel warning” means the place is not named in the regional lists; it does not mean there is no risk.
