Is Mexico City safe for tourists?

Yes, the main tourist areas including Centro Historico, Roma, Condesa, and Polanco are heavily walked and policed. Use normal big-city precautions: avoid flashing phones on the Metro, use Uber or Didi instead of street taxis at night, and stick to well-lit streets.

Do I need to worry about altitude sickness in Mexico City?

Mild symptoms like headache or shortness of breath on stairs are common in the first day or two since the city sits above 7,300 feet. Drink extra water, limit alcohol the first night, and ease into strenuous hikes.

Can I drink the tap water in Mexico City?

No, stick to bottled or filtered water, including for brushing your teeth if you want to be extra cautious. Ice at reputable restaurants is generally made from purified water and is fine.

What is the best way to get around Mexico City without renting a car?

Combine the Metro for cheap, fast cross-town trips, Uber or Didi for late nights or longer distances, and walking within neighborhoods like Roma, Condesa, and the Centro Historico, which are flat and compact.

When is the best time to visit Mexico City?

November through April is the dry season with mild days and cooler nights, making it the most comfortable stretch. Rainy season from May through October still has sunny mornings with short, predictable afternoon showers.

How much cash should I carry in Mexico City?

Enough pesos for taco stands, markets, and cantinas, which are often cash-only, roughly 300 to 500 pesos a day for food and small purchases. Cards are widely accepted at restaurants, museums, and hotels.

Mexico City will rearrange everything you thought a Latin American megacity looks like, in the best way, but a few practical surprises catch almost every first-timer off guard. Here is what actually matters before you land.

The altitude is the first thing to plan around

Mexico City sits at more than 7,300 feet above sea level, higher than Denver, and you will feel it. Stairs at the Chapultepec Castle hit differently on day one than day three. Drink more water than feels necessary, go easy on alcohol the first night, and do not schedule a big hike up something like Parque Nacional Cumbres del Ajusco until you have acclimatized for at least a day or two. The thin air also means the sun burns faster than it looks like it should, even on a mild 68F afternoon.

Weather and when to go

The dry season runs roughly November through April, with warm days near 75F and cool nights that can drop into the 40s F, especially in December and January. Rainy season (May through October) brings predictable late-afternoon downpours, usually an hour of heavy rain around 4 or 5 p.m. and clear skies the rest of the day, so it rarely ruins a trip. Smog and haze are most common in the spring months of March through May.

Getting around without a car

Renting a car here is a mistake almost every visitor who tries it regrets. Traffic is dense, parking is scarce, and the Metro, Metrobus, and ride-hailing apps cover the city far better.

The Metro costs about 5 pesos (around 25 cents) a ride and is the fastest way across town during rush hour.
Uber and Didi are both reliable and far safer than hailing a taxi on the street.
Walking is genuinely the best way to see the Centro Historico, Roma, and Condesa, all of which are flat and dense with things worth stopping for.

Safety, water, and money basics

Mexico City is safer for visitors than its old reputation suggests, but use the same street sense you would in any large city: stick to well-lit streets at night, keep phones out of sight on the Metro, and use official taxi stands or apps rather than flagging cars. Tap water is not safe to drink; bottled or filtered water is cheap and everywhere. Carry pesos for taco stands, markets, and cantinas like La Opera, since many smaller spots are cash-only, but cards work fine at restaurants, museums, and hotels.

What to actually see first

Start at the Zócalo, the vast square anchored by the Mexico City Metropolitan Cathedral and the National Palace, then walk two blocks to the excavated Templo Mayor Museum to understand what stood here before the Spanish arrived. From there it is a short walk to the tiled facade of Casa de los Azulejos and the gold-leaf interior of Palacio de Bellas Artes. Save a full morning for the Museo Nacional de Antropología inside Bosque de Chapultepec, widely considered the best anthropology museum in the Americas, and do not rush it.

Food logistics worth knowing

Street food is one of the best reasons to visit, and a taco stand doing steady business with a line of locals, like Los Cocuyos or Tacos El Huequito, is almost always a safer and better bet than an empty one. If you would rather have a guide explain what you are eating, a outfit like Eat Like a Local Mexico - Food Tours walks small groups through mercados and fondas most visitors never find solo.

FAQ-worthy details

Tipping runs 10 to 15 percent at sit-down restaurants, and it is customary to tip a few pesos to the person bagging groceries or pumping your gas. Most restaurants add a small cover charge if you see it listed as "cubierto." English is spoken at hotels and major sights but less so at street stalls and smaller neighborhood spots, so a translation app or a few basic Spanish phrases go a long way.

How to save money in Mexico City

Most federal museums, including the Museo Nacional de Antropología and Chapultepec Castle, are free for everyone on Sundays, and always free for Mexican residents with ID, so expect bigger crowds that day if you go then. The Metro at roughly 5 pesos a ride beats any single Uber fare for crossing town, and a stored-value Metro card avoids line-ups at the machines. Eat where the lines of office workers eat at midday: a comida corrida set lunch at a spot like Mamá Carmela runs 80 to 120 pesos (about $5 to $7) for soup, a main, and agua fresca, roughly half what the same calories cost in a Polanco restaurant. Flights from the US tend to drop in price in September and early November, after summer crowds and before the December holiday surge.

Mexico City travel hacks

Download Uber or Didi before you land since street taxis are harder to vet and airport taxi stands overcharge. The Chapultepec Castle gets a quiet window right at opening, 9 a.m., before tour buses arrive by 11. For the Museo Nacional de Antropología, go on a weekday afternoon, since Sunday's free admission for residents packs the courtyard. Save Tianguis Cultural del Chopo for a Saturday, it only runs that one day a week. Many smaller museums and the Templo Mayor site close on Mondays, so build your Centro Historico day around a Tuesday through Sunday visit. If you are prone to altitude headaches, chamomile tea and a slow first 24 hours work better than painkillers alone.
