Mexico City First-Timer Guide: Altitude, Safety & Getting Around the Capital
Mexico City intimidates first-timers with its sheer scale — 22 million people across a sprawling valley, headlines about cartels, and an altitude that literally takes your breath away. The reality on the ground is far more welcoming than the perception. This is a modern, cosmopolitan capital with world-class infrastructure, genuinely warm people, and a pace of life that invites rather than overwhelms.
This guide covers the practical details that make the difference between confusion and confidence: getting from the airport to your hotel, which neighborhoods to stay in, how to handle the altitude, and the honest safety picture.
Airport to City: AICM (MEX)
Understanding the Airport
Aeropuerto Internacional de la Ciudad de Mexico Benito Juarez (AICM) has two terminals connected by a free shuttle bus (every 10 minutes) or monorail. Terminal 1 handles most international flights. Terminal 2 serves Aeromexico and some domestic carriers. Confirm your terminal before booking ground transport.
Immigration lines can stretch to 90 minutes during peak arrivals (noon-3 PM from US/Europe flights). The customs process uses a traffic light system — green means go, red means bag inspection. It's random.
Getting to Your Hotel
Authorized airport taxis operate from booths inside both terminals. Buy a ticket at the booth (not from drivers outside), choose your destination zone, and present the ticket to the driver. Rides to Roma/Condesa cost MXN 250-350 ($15-21). Centro Historico is MXN 200-280 ($12-16). Prices are fixed and non-negotiable.
Uber works reliably from AICM but pickup is in designated areas (follow signs to "Ride App" pickup zones). Rides to Roma/Condesa run MXN 120-200 ($7-12) — significantly cheaper than authorized taxis. However, traffic between 4-8 PM can double both the time and the surge price.
The metro connects directly to Terminal 1 (Line 5, Terminal Aerea station) for MXN 5 ($0.30). It's fast and efficient but not practical with large luggage during rush hour — the crowds are intense. Ideal for backpackers traveling light during off-peak hours.
Where to Stay: Neighborhoods Explained
Roma Norte / Condesa — Best for First-Timers
Adjacent neighborhoods with tree-lined streets, excellent restaurants, cafes on every corner, and a walkable scale that feels manageable in a massive city. Roma has more culture (galleries, bookstores, art nouveau architecture). Condesa has more parks (Parque Mexico, Parque Espana) and a slightly more residential feel. Both are safe for walking day and night.
Centro Historico — Best for History and Budget
The colonial heart of the city, built literally on top of the Aztec capital. The Zocalo, Templo Mayor, Palacio Nacional, and dozens of museums are walking distance. Hotels are cheaper than Roma/Condesa. The neighborhood is lively during the day but some streets empty at night — stick to the main avenues after dark.
Polanco — Best for Luxury
Mexico City's wealthiest neighborhood has designer shopping, fine dining (Pujol, Quintonil), and Chapultepec Park on its doorstep. Hotels start at MXN 3,000+ ($176+) per night. It's safe, polished, and expensive — think Upper East Side Manhattan at Mexican prices.
Coyoacan — Best for Bohemian Vibes
A colonial-era village absorbed by the city's growth, Coyoacan retains a distinct village atmosphere. Frida Kahlo's Casa Azul, cobblestone streets, and a lively plaza make it charming but slightly far from central attractions. Better as a day trip than a base, unless you prioritize atmosphere over convenience.
The Altitude: 2,240 Meters
Mexico City sits at 2,240 meters (7,350 feet) above sea level — higher than Denver. If you're coming from sea level, you will feel it. Symptoms range from mild (slight breathlessness climbing stairs) to uncomfortable (headaches, fatigue, poor sleep, light nausea) in the first 24-48 hours.
Most people adjust within 2-3 days. To minimize discomfort: drink significantly more water than usual (the dry air compounds dehydration), limit alcohol and heavy meals on day one, walk slowly on inclines, and don't schedule strenuous activities for your first morning. Climbing the Teotihuacan pyramids on day one is a common mistake.
Getting Around
Uber vs Metro
Both are essential. The metro (MXN 5 per ride) covers the major axes of the city on 12 lines. Use it for trips to the Centro, Chapultepec, bus terminals, and Coyoacan (Line 3 to Coyoacan station). Uber (MXN 40-150 per ride) is better for door-to-door trips, late nights, and neighborhoods not well served by metro.
Avoid the metro during rush hour (7-9 AM, 6-8 PM) unless you enjoy being physically compressed. The women-and-children cars at the front of the train are less crowded during these times and enforced by platform attendants.
Walking
Roma, Condesa, and the Centro Historico are highly walkable. Sidewalks are uneven — watch your step, literally. Mexico City drivers are aggressive with pedestrians, even at crosswalks. Make eye contact with drivers before crossing, and don't assume a green walk signal means cars will stop.
Safety: The Honest Version
Tourist Areas
Roma, Condesa, Polanco, Coyoacan, and the main Centro Historico streets are safe for walking during the day and evening. Violent crime against tourists in these areas is rare. Petty theft (phone snatching, pickpocketing on crowded metro) is the primary concern. Keep your phone in your front pocket and don't flash expensive electronics.
Precautions
Use Uber or authorized taxis at night instead of hailing street cabs. The "taxi seguro" (safe taxi) apps (Uber, DiDi, InDriver) provide tracked rides with driver identification. Avoid withdrawing money from standalone ATMs — use bank-attached ATMs during banking hours. Don't carry large amounts of cash or wear flashy jewelry.
The outer colonias (Tepito, Iztapalapa, parts of Neza) have higher crime rates and no tourist infrastructure. There's no reason to visit these areas, and locals will tell you the same.

Mexico City rewards first-timers who arrive with reasonable preparation and an open mind. The altitude adjusts, the metro becomes second nature, and the city reveals itself as one of the most culturally rich and affordable capitals on Earth. Once the initial orientation clicks, you'll understand why travelers keep coming back. For trip planning, pair this guide with our Mexico City 3-day itinerary.
