Things to know before visiting Mexico
You don’t need to know everything about Mexico before you visit — your first trip to a country is a learning experience. But if you make note of these sixteen essential travel tips, you can hit the ground running (even if you’re just running to the nearest beach).
1. Beware the “Two laptop rule” at customs
This one catches a lot of people out at the border, especially digital nomads. Mexican authorities limit how many “portable computing devices” you can bring into the country at once. You can pack two devices for free (laptops and tablets — phones are excluded), but any extras will incur a 19% tax on their value. According to official guidance from the Mexican government, items that fall under the portable computing category include “a desktop or laptop machine, notebook, Omnibook, or similar.”
2. Vapes and e-cigarettes are strictly illegal
Staying in the realm of tech and customs controls, you can’t bring a vape across the Mexican border. Under the new 2026 legislation, vapes of any kind are illegal to import or sell within the country, and the penalties can be severe. If one of these devices is found in your baggage, you could be looking at fines of US$400 or more. Leave your vape at home — you can go without it for one trip!
3. The 2026 “propina” (tipping) rules
Tipping isn’t mandatory in Mexico, but it’s very welcome. You can add 15% to your card payments as a baseline for good service, though many businesses might prefer cash tips. Some tourists go as high as 30% to show their appreciation, but you have the final say. PROFECO, Mexico’s Federal Consumer Protection Agency, forbids businesses from trying to force you to tip — it’s always optional, even in busy tourist zones.
4. Always decline the USD conversion on card machines
Whenever you pay with a card, you’ll usually see a message on the screen asking if you want to pay with “USD or MXN.” The smart move is always to choose MXN (Mexican pesos), because this allows your home bank to handle the conversion, and usually costs you less. Just remember that Mexico uses the familiar “$” symbol for pesos, so if you see $100 on a menu, that’s not US$100 — it’s probably closer to US$6. For US citizens, the cost of living in Mexico is actually quite low, but it can be a shock the first time you see what you think are dollar prices.
Cash vs. card: Where each works
You can make card payments in most hotels, touristy food spots, upmarket restaurants, chain stores, and supermarkets. Save your cash for street food vendors, fondas (small, family-run diners), taxis, and tips. When you’re pulling out cash, make sure to use ATMs inside banks, instead of going to machines on the street, which carry far more risk of theft and limit skimming.
5. Do not drink tap water
Avoid drinking tap water in Mexico under any circumstances. Even if filtration plants purify water, it then runs through pipes that might be leaking and filled with bacteria. Bottled water is cheap and very widely available, and even in resorts and tourist hubs, that should be your first choice. This applies to brushing your teeth, too — use safe, bottled water every time. It might seem like a hassle, but you know what’s even more of a hassle? A severe E. coli infection.
6. Paper entry forms are gone (FMMd)
The days of Mexico’s paper immigration forms at major airports are over — we’re in the digital age now! After passport control, your physical stamp serves as your official proof of entry, while a digital record of your arrival is also generated. While you can optionally download a tourist card (FMMd) from the online INM portal, that’s not required. When you leave Mexico, just scan your passport at check-in — the airline matches your document with your digital record automatically, without the need for extra papers.
7. Stay safe on the roads with the “Green Angels”
If your car breaks down in Mexico, you can dial 078 to call the Ángeles Verdes, or Green Angels. This is a free government-run service that patrols larger highways and offers mechanical help, first aid, and other kinds of support to stranded drivers. Before you ever need their assistance, though, you can take some steps to stay safe yourself. Drive on official toll roads rather than libres (the toll-free roads that are typically less maintained and patrolled). This is doubly true at night, when visibility drops and roadside robberies are more likely.
8. Use WhatsApp for (almost) everything
If you don’t use WhatsApp already, you will by the time Mexico’s done with you. Local businesses, tour guides, and even some transport services depend on the app for bookings and customer communication. Getting a shuttle bus ticket, checking a restaurant’s opening hours, nabbing a spot on a tour — it’s all done with WhatsApp, and you’ll need a decent internet connection to run the app. Remember, even if your phone works in Mexico, you can’t use WhatsApp unless you’re online (with data roaming, a local SIM card, or an eSIM app like Saily).
9. Skip carrier roaming and download a travel eSIM
You’ll need internet in Mexico, and unless you want to blow your birria budget on data roaming, the best option is to use a travel eSIM. But what is an eSIM, exactly? eSIM apps like Saily let you install temporary mobile data plans on your device, without having to find a physical SIM card or go hunting for public Wi-Fi networks. Just download the eSIM app, find the plan that works for you, and get connected. If you’re moving to Mexico or considering a long-term stay (several months at least), go for a local SIM card instead — anything but data roaming, really.
10. Ride the new Tren Maya (Mayan Train)
Heading for southeastern Mexico? Take the Tren Maya! Mexico’s newest rail line loops through five states — Yucatán, Quintana Roo, Campeche, Tabasco, and Chiapas — making travel within the country easier than it’s ever been. Going by the Tren Maya, you can visit tourist hubs like Cancún, Mérida, Palenque, and Chichén Itzá without stressing over bus connections or internal flights.
11. Use only official means of transportation
If you’re not on the Tren Maya, stick to major bus companies like ADO or ETN — they’re comfortable, reliable, and staffed by people who are used to dealing with tourists. Within cities, Uber is usually available and should be the safest default. Alternatively, the Didi app can also be relied on when Uber isn’t around (even if you don’t plan to use it, install it on your phone as a backup). When all else fails? Look for official Sitio taxi stands instead of picking one up on the street.
12. Take luxury intercity buses
Remember those buses we just mentioned? ADO, in particular, is one of several coach companies moving into the luxury intercity niche. Even if you don’t typically enjoy bus travel, ADO might be the exception. You can expect spacious vehicles with reclining seats, AC, onboard entertainment, and bathrooms on some longer routes. It’s not the cheapest transport in Mexico, but you do get a higher standard of comfort for your money.
13. Visit Mexico from December to April for the best weather
Timing really determines what side of Mexico you see on your trip. The dry season (December to April) is the best time to visit Cancun, La Paz, and other coastal areas (assuming you want sunshine and not storms). The trade-off is that you won’t be getting the beach to yourself — expect big crowds and higher prices. For a more relaxed, budget-friendly trip, travel outside of peak season.
14. Visit Mexico from May to November for the best budget trips
Mexico sees fewer tourists between May and November, so the prices of hotels, resort experiences, and flights all start to drop. So what’s the catch? Between July and October, tropical storms batter the country, and hurricanes can occur regularly. If you’re going during hurricane season, pay close attention to weather warnings and government safety alerts.
15. Stay in Level 1 areas as much as possible
Safety in Mexico all comes down to the area you’re in. The US State Department ranks Mexican states on a risk scale from one to four, with Level 1 being the safest for travelers. Level 2 is also generally low-risk, but stick to Level 1 as much as possible. While much of the country is classed by the US as Levels 3 and 4, tourist hubs tend to be in the safest regions. Stick to them, and you won’t have too much to worry about.
16. Street food? Yes, eat it!
You’ll find the best food in Mexico in streets and markets, rather than restaurants. To make sure you’re staying safe and healthy, look for stalls where food is cooked fresh right in front of you — preferably with a long line of locals standing by. If you see pre-cut fruit, salads, or anything with mayo or cream sitting out unrefrigerated, steer clear. As a precaution, pick up rehydration salts and a basic anti-diarrheal from a local pharmacy. You might not need them, but it’s best to play things safe.
