Mexico Packing List

Documents first, because this one is different

Mexican authorities can ask to see your passport and your entry stamp, and copies and photographs are not accepted. If you cannot produce them you may be questioned, detained while your status is checked, and in some cases deported.

That inverts the habit most travelers have of leaving the passport in the safe. Carry it, carry it securely, and retrieve the digital registry of your entry documents from the national immigration portal in your first days as a backup rather than a substitute.

• Passport valid for the whole stay, and longer if you transit another country.
• The entry stamp, which is in the same passport, and the number of days written on it.
• Travel insurance covering your activities, with the policy number reachable without a signal.
• More than one card, carried separately.
• Written confirmation from the consulate if any part of the trip could be called research.

The two climates

Highland cities

Mexico City, Puebla, San Miguel de Allende, Guanajuato and the Oaxaca valleys are all above two thousand meters. Warm afternoons, cold evenings, and frequently unheated rooms.

• Layers: a light base, a fleece or light down, and something windproof.
• A warm layer for the evening in every month, and a proper jacket in January and February.
• Comfortable shoes with grip. Colonial centers are cobbled and steeply cambered.
• High factor sunscreen, a brimmed hat and sunglasses. The sun at altitude is stronger than the temperature suggests.

The coasts and the Yucatan

• Light, quick drying clothing. Humidity rather than heat is what tires people.
• Insect repellent, and long sleeves for dusk. Dengue, chikungunya and Zika are named for Mexico, and none of them has a vaccine most travelers will have, so bite avoidance is the whole strategy.
• Reef safe sunscreen. Several protected areas and cenotes require it and some will not admit you without it.
• Water shoes if cenotes or rocky shorelines are in the plan.
• Rain protection from June through October, and a dry bag.

Health items

See a travel clinic ideally eight weeks before departure. Two things are worth knowing before that appointment, because they save worry:

• The CDC records yellow fever vaccine as neither recommended nor required for Mexico.
• Malaria transmission is limited to Campeche, Chiapas and the southern part of Chihuahua, is rare in Oaxaca, Sinaloa, Sonora and Tabasco, and there is none along the United States border. Quintana Roo, Yucatan and the capital are not transmission areas, which covers most itineraries.

What actually needs planning is food and water. Only drink boiled or bottled water, avoid ice in drinks outside established venues, and be aware that Cyclospora, a food and water parasite, has been reported in travelers returning from Mexico.

• Rehydration salts.
• Anything you take regularly, in original labeled packaging, in your carry on, with a copy of the prescription. Some medicines sold over the counter at home need a local prescription.
• A small first aid kit, and blister treatment if you are walking archaeological sites.
• Hand sanitizer.

This page publishes no medication and no dose. What to take, if anything, is a conversation with your own clinician.

Things worth leaving behind

• Vaping devices, e-cigarettes and solutions. They may not be brought into Mexico, or bought or sold there, and customs confiscate them.
• Jewelry and anything expensive on display.
• Drone equipment, unless you have checked where it may be flown and whether your activity could be read as research.
• The assumption that a photocopy of your passport is enough, which it is not.

Small things that earn their space

• A refillable bottle with a filter, which removes most of the bottled water problem.
• Small notes and coins for tips, toll roads and bathrooms.
• A basic Spanish phrase list. English is common in resorts and much less so elsewhere.
• Earplugs. Mexican towns are cheerfully loud, and that is part of the pleasure rather than a fault.

Verify before you travel

Vaccine recommendations, medication rules and baggage allowances change. Confirm with a travel clinic and your airline close to departure.
