Mexico packing is more nuanced than most destinations. In a single two-week trip you might move from Mexico City at 2,240m (bring layers) to Caribbean beach (pack reef-safe sunscreen) to Oaxacan highlands (cool nights). Here is the complete breakdown.
In a single two-week Mexico trip you can go from a 10°C highland night to a Caribbean cenote swim to a rooftop mezcal bar — pack for all three, not just one.
- Beach (Cancun/Tulum)Lightweight, rash guard, rash shoes
- Highland cities (CDMX/OAX)Layers, walking shoes, rain jacket
- RuinsLong pants, hat, closed-toe shoes
Power and Plugs
Type A/B, 127V — same as the United States. American devices work without any adapter. Europeans and Australians need a Type A/B adapter (inexpensive, get one before you leave — airport adapters are overpriced).
127V is slightly lower than the US standard 120V — no issue for any modern electronic. All modern phone chargers, laptops, and cameras handle 110-240V automatically.
Sun Protection — The Non-Negotiable
Mexico has extreme UV levels, especially on the Yucatan Peninsula. SPF 50+ is the minimum — reapply every 90 minutes regardless of what the bottle says.
Critical for cenotes and ocean swimming: Conventional sunscreen containing oxybenzone and octinoxate is banned at cenotes and increasingly in Cancun and Tulum marine areas — rangers will turn you away. Pack biodegradable/mineral sunscreen (zinc oxide or titanium dioxide) for any water activities.
Bring biodegradable sunscreen from home. Standard sunscreen (oxybenzone/octinoxate) is banned at cenotes and Tulum/Cancun marine areas — rangers actively turn people away. Zinc oxide or titanium dioxide mineral sunscreen works. The selection at cenote entrances is limited and overpriced.

Clothing
For Beach Destinations (Cancun, Tulum, Puerto Vallarta, Huatulco)
- Lightweight clothing — linen, cotton, moisture-wicking synthetics
- At least 2 swimsuits (drying time in humidity can be slow)
- Rash guard for snorkeling — also protects from sun
- Reef shoes or water sandals
- Light jacket or long sleeves for over-air-conditioned restaurants and transport
- Sundress or light pants for evening dining
For Highland/Colonial Cities (Mexico City, Oaxaca, San Miguel, Guanajuato)
- Layers are essential — nights at elevation can be 10-15C even in summer
- At least one warmer layer (fleece or light jacket)
- Comfortable walking shoes with ankle support — cobblestones are uneven
- Light rain jacket (June-September afternoon showers in CDMX and Oaxaca)
For Ruins and Archaeological Sites
- Long pants or lightweight convertible pants for climbing — knees appreciate the padding
- Hat with brim — mandatory at Chichen Itza, Teotihuacan, Monte Alban
- Sturdy closed-toe shoes — ruins have uneven stone, sharp edges
- Extra socks — you will sweat more than expected
Health Essentials
Water: Never drink tap water in Mexico. Buy bottled water at every destination — it is cheap and available everywhere. Use bottled water to brush your teeth if you want to be cautious.
Stomach: Mexico City and smaller towns can cause traveler’s diarrhea. Common remedies to pack: Imodium, oral rehydration salts, Pepto-Bismol tablets. Probiotics taken daily starting 1 week before departure significantly reduce risk.
Altitude: For Mexico City and Oaxaca — altitude sickness medication (acetazolamide/Diamox) is prescription. Ask your doctor if you have concerns. Most people manage with hydration and rest.
Mosquitoes: Dengue fever is present in tropical coastal areas. Pack DEET-based repellent (30%+) for evenings in Cancun, Tulum, Puerto Vallarta, and Oaxacan coast. The Yucatan and coast have year-round mosquito activity.
Documents
- Passport (valid 6+ months beyond travel dates)
- Travel insurance documents (printed)
- Copies of passport separate from original
- Yellow fever certificate if arriving from South America or Africa
- Emergency contacts and insurance hotline numbers
Money
- MXN pesos — have cash for markets, street food, small towns, cenotes
- US dollars are widely accepted in tourist areas but at unfavorable exchange rates
- ATMs: Use airport or bank ATMs rather than tourist-area machines. Notify your bank before traveling to avoid card locks
- Carry some cash always — many cenotes and rural markets are cash-only
What to Leave Home
- Adapters from US: Not needed — same plug as USA
- Heavy guide books: Everything is on your phone
- Hair dryer: Every decent hotel provides one
- Towels: All accommodation provides them
- Denim jeans: Too hot for most of Mexico, too heavy, slow to dry
Packing for Our Mexico Itinerary (12 Days, 3 Regions)
For the Mexico City → Oaxaca → Yucatan trip, Scott packs in a 40L carry-on only. The key to making this work: do laundry in Oaxaca. Most hotels offer same-day laundry service for MXN 100-150 per load. Rolling clothes instead of folding saves significant space.
