Before traveling to Mexico, it’s important to know what not to do in Mexico to avoid surprises. Respecting a few key rules will help you enjoy your trip to the fullest. Here are 13 things you should never do, for a smooth and stress-free stay.
Drinking alcohol in public spaces
One of the most common mistakes travelers make is drinking alcohol in public. In Mexico, it’s forbidden to consume alcoholic beverages on the street or in public areas. You could face a fine, and the drinks may be confiscated.
Smoking in public places
While some places might turn a blind eye, Mexican law prohibits smoking in enclosed public spaces, including bars, restaurants, and public transportation. If you’re caught, expect a fine.
Being forced to leave a tip
This question comes up a lot in touristy areas, where tips are sometimes automatically added to the bill. But in reality, tipping isn’t mandatory in Mexico. That said, it’s customary to leave around 10%, or more for great service, especially since wages in the hospitality industry can be quite low.
Urinating in public
Yes, it needs to be said: urinating in public is strictly prohibited in Mexico. Authorities enforce this rule strictly, especially at night in tourist areas — often outside bars and clubs — and fines (or worse) are common.
Airport food restrictions
Bringing certain foods into Mexico is prohibited — especially fresh fruit, meat, dairy products, and plants. These rules are meant to prevent the spread of pests and diseases.
Alcohol sales ban at specific times
Alcohol isn’t available at all hours in Mexico. In many regions, sales are restricted at night or on Sunday evenings. During elections, a full ban called ley seca (« dry law ») applies the day before and on voting day.
No wild camping
Wild camping is strictly regulated in Mexico. Travelers are expected to stay at official campgrounds — not only to protect the environment but also for personal safety.
No photos of sensitive sites
Taking photos of military installations or certain government buildings is not allowed. Authorities may confiscate your camera or fine you if you ignore this rule.
Drug use: what’s allowed and what’s not
Since 2021, it’s legal to possess small amounts of cannabis (up to 5 grams) for personal use in Mexico. However, growing, selling, or distributing it remains illegal.
All other drugs are strictly prohibited, possession or use can lead to severe jail time.
Respect for conservation areas and national parks
Mexico’s conservation zones and national parks are protected to preserve their unique biodiversity. It’s forbidden to leave marked trails, pick plants, or disturb wildlife.
Fishing restrictions in protected marine areas
Fishing is not allowed in certain marine reserves to help preserve biodiversity. Anyone fishing in Mexico must follow local regulations to avoid fines or penalties.
No firearms without a permit
Bringing firearms into Mexico without special authorization is illegal — and violations can lead to serious jail time.
No disruptive behavior in tourist zones
Drunkenness, excessive noise, or vandalism are strictly prohibited in tourist areas. These rules are enforced to keep public spaces safe and enjoyable for everyone.
Respecting local laws and customs is key to enjoying your stay in Mexico. By knowing what not to do, you’ll avoid legal trouble and help protect the country’s culture and environment.
