Published on November 24, 2025

As winter sets in, Los Cabos, Mazatlan, Colima, Guerrero, Michoacan, Sinaloa, Tamaulipas, and nearby regions are experiencing a significant surge of U.S. travelers drawn to warmer climates and holiday escapes. This sharp increase in winter tourism has triggered urgent safety alerts, highlighting crime risks, road hazards, and other potential threats even in well-known tourist areas. Travelers are strongly advised to stay informed, comply with legal requirements, carry proper travel documents, and remain vigilant throughout their visits. With rising visitor numbers, high-risk zones, and strict enforcement of customs and transportation regulations, careful planning and awareness are essential to ensure a safe and smooth winter travel experience.

Heightened Awareness in Popular Tourist Areas
Mexico continues to be a top destination for U.S. travelers, yet the advisory underscores that crime, including violent incidents, can occur even in well-known tourist and expat communities. Visitors are encouraged to exercise extra caution in winter hotspots such as San Carlos, Puerto Peñasco, Los Cabos, and Mazatlán, particularly during nighttime hours.

Certain regions of Mexico remain subject to elevated risks, consistent with the broader Department of State Travel Advisory. Areas with persistent violence, cartel activity, and limited law enforcement presence are highlighted, including states like Colima, Guerrero, Michoacán, Sinaloa, and Tamaulipas. In some locations, travelers may encounter armed groups or roadblocks, and specific zones, such as parts of Oaxaca, have restricted access for government personnel due to safety concerns.

Entry Requirements and Legal Guidelines
All travelers entering Mexico must obtain a Forma Migratoria Múltiple (FMM), regardless of their border entry point. This document should be kept secure and presented upon departure. The current fee is $861 MXN (roughly $47 USD) and will increase to $983 MXN (around $54 USD) starting January 2026.

Travelers must ensure passports are valid for the duration of their stay. Minors traveling by domestic air within Mexico require a passport book rather than a passport card.

Customs regulations are strictly enforced. Cash amounts exceeding $10,000 USD must be declared, tax-free goods are limited, and temporary vehicle import rules must be observed for those entering by car. Importing firearms, ammunition, knives, fireworks, or other restricted items without permits is a serious offense with severe legal consequences.

Road Travel Safety Considerations
Driving in Mexico requires particular caution. Travelers may encounter both official checkpoints managed by military or police and unauthorized checkpoints operated by criminal groups. In all situations, it is advised to stop, remain calm, and avoid any behavior that could be interpreted as suspicious or confrontational.

Emergency medical services may be limited in rural or remote areas, making it essential to plan ahead. The advisory strongly recommends securing travel insurance that covers medical emergencies and evacuation.

Strict Drug Laws and Criminal Awareness
Drug possession, including medical marijuana, remains illegal in Mexico. Penalties can be severe, including lengthy prison sentences. Travelers are also warned against transporting packages or goods for others, as criminal organizations may attempt to exploit unsuspecting individuals.

Safety Recommendations for Travelers
The advisory provides practical steps for reducing risk and ensuring a smooth trip:

• Enroll travel plans in the Smart Traveler Enrollment Program (STEP)
• Keep passports and FMM documents secure and accessible
• Share travel itineraries with trusted contacts
• Confirm international health insurance coverage
• Call 911 for emergencies or 078 for Green Angels roadside assistance on federal toll roads
• Utilize tourist support centers for guidance when needed

Millions of visitors travel safely to Mexico each year, but staying alert, understanding local laws, and following official guidance are essential to a secure and pleasant experience.
