You're standing at the bottom of a concrete staircase in the middle of the Paseo de la Reforma. The air smells like fried dough and exhaust. Below you, a literal subterranean city pulses with the energy of five million daily commuters. If you’ve ever looked at the Mexico City subway map—officially known as the Sistema de Transporte Colectivo (STC) Metro—it looks less like a transit guide and more like a plate of technicolor spaghetti.
It’s overwhelming. Really.
But here is the thing about the CDMX Metro: it was designed by people who understood that not everyone could read. Back in 1969, when the first segment of Line 1 opened, literacy rates weren't what they are today. So, Lance Wyman—the design genius behind the 1968 Olympics branding—created a system of icons. Every single station on the Mexico City subway map has its own picture. Want to go to Pino Suárez? Look for the Aztec altar. Heading to Chapultepec? Look for the grasshopper. It is arguably the most intuitive transit design on the planet, yet tourists still stare at the maps with a look of pure, unadulterated terror.
Decoding the colors and icons
Basically, the system is divided into 12 lines. Most of them are numbered 1 through 9, followed by 12, plus two lettered lines (A and B). Don't ask me why they skipped 10 and 11; it's just one of those quirks of Mexican bureaucracy that you learn to live with.
The Mexico City subway map uses a specific color for each line. Line 1 is pink. Line 2 is blue. Line 3 is olive green. If you're trying to navigate, you don't really look for "North" or "South." You look for the dirección. The direction is always the name of the final station on that line. So, if you're on the Green Line (Line 3) and you want to go to the Coyoacán neighborhood, you need to follow signs for Dirección Universidad. If you're heading toward the Basilica, you're looking for Dirección Indios Verdes.
It sounds simple. It isn't always.

The icons are the real lifesaver. Take the station Salto del Agua. The icon is a stylized fountain. Why? Because that’s where the historic colonial aqueduct ended. Pantitlán, the massive interchange where four lines meet, features a flag icon, referencing the Aztec place name "between flags." Honestly, once you start associating the pictures with the neighborhoods, the map stops being a chaotic mess and starts being a history lesson.
Why the map lies to you (sorta)
The biggest mistake people make is trusting the scale of the Mexico City subway map. It’s a schematic, not a geographic representation.
Look at the transfer stations, or correspondencias. On the map, they look like a simple dot where two lines cross. In reality? Some of these transfers are endurance sports. La Raza is the most famous example. The transfer between Line 3 and Line 5 involves walking through the "Tunnel of Science," a long, arched hallway filled with astronomy displays. It is beautiful, but it is also nearly half a kilometer long. If you have heavy luggage, that little dot on the map is your worst enemy.
You also have to account for the "Metro effect" on your internal compass. Because the city is built on a soft lakebed, the stations are deep. By the time you wind your way through the tunnels of Polanco or Auditorio (Line 7, the orange one), you will have zero idea which way is North.
Line 7 is the deepest in the system. It was built that way partly for geological reasons and partly, according to local legend, to serve as a makeshift bomb shelter. When you're looking at that orange line on the Mexico City subway map, remember that you’ll be riding escalators for what feels like an eternity before you see daylight.
The "secret" lines and the 2026 reality
If you're looking at a map from five years ago, throw it away. Seriously.
The system has been through a lot lately. Line 1 (the Pink Line) has been undergoing a massive, multi-phase modernization project. For a long time, half the line was just... closed. They’ve been replacing tracks, systems, and trains that were literally half a century old. As of early 2026, the system is finally starting to feel like a modern 21st-century transit network rather than a vintage museum piece.
Then there’s Line 12, the Gold Line. Its history is, frankly, tragic. After the structural collapse in 2021, the line was closed for extensive reinforcement. While it’s back on the Mexico City subway map and fully operational now, many locals still approach it with a bit of hesitation. It’s the most modern-looking line—clean stations, shiny trains—but it represents a complex chapter in the city’s engineering history.
Don't forget the "other" maps. The Metro is just one part of the Movilidad Integrada system. You’ve got the Metrobús (BRT), the Cablebús (gorgeous cable cars over the hills), and the Trolebús. Usually, you can find an integrated map that shows all of these together. If you're trying to get to the more rugged parts of the city, like Iztapalapa, you’re going to be looking for those cable car connections.
Real-world survival tips for the CDMX Metro
The map won't tell you about "The Push."
If you're riding during hora pico (rush hour), the Mexico City subway map becomes secondary to the physical reality of being squeezed into a car with 300 of your closest friends.
- Gender Segregation: In almost every station, the first few cars are reserved for women and children under 12. This is strictly enforced by police during peak hours. If you're a man and you wander into that zone, you're going to get whistled at, yelled at, or fined. Look for the "Solo Mujeres" signs on the floor and the metal barriers on the platforms.
- The Card: Don't even try to buy paper tickets. They’re basically extinct. You need a Tarjeta de Movilidad Integrada. You can buy them at vending machines in most stations. It costs about 15 pesos for the card, and each ride is a flat 5 pesos. That’s roughly 25 cents in US dollars. It’s arguably the best deal in the world.
- The "No-Go" Items: You can't bring large bikes during peak hours, and honestly, trying to bring a massive suitcase into Hidalgo at 6:00 PM is a recipe for a bad time.
- Keep your phone tucked away: While the Metro is generally safe, "pickpockets" is an understatement in a crowded car. Don't stand by the doors with your phone out checking the Mexico City subway map. Memorize your transfer or take a quick peek when you’re against a wall.
Nuance and common misconceptions
One thing you'll hear people say is that the Metro is "dangerous."
Is it chaotic? Yes. Is it loud? Absolutely. Between the "vagoneros" (vendors) shouting about $10-peso power banks and the sheer volume of humanity, it’s a sensory assault. But is it dangerous? Not more than any other massive city's transit. Most "danger" is just people not knowing the etiquette.
Another misconception is that the Metro goes everywhere. It doesn't.
If you look at the Mexico City subway map, you'll notice a massive empty space in the west. That’s where the posh neighborhoods like Lomas de Chapultepec are. Wealthy residents historically didn't want the Metro in their backyard. If you're heading to those areas, the map won't help you much; you'll be switching to the Metrobús or an Uber.
Also, the map suggests that Line 9 (the Brown Line) is a great way to skip the traffic. It usually is, but since it's an elevated track for much of its run, it has been subject to various maintenance closures recently to deal with "subsidence"—which is the polite engineering way of saying the city is sinking and taking the tracks with it. Always check the official STC Twitter (X) or the Metro app before assuming a line is 100% open.
Actionable steps for your first trip
- Download the "Metro-Metrobús México" app. It’s better than Google Maps for this specific task because it accounts for real-time closures and shows the icons clearly.
- Buy your card at a less busy station. If you try to buy a card at Zócalo or Bellas Artes, you’ll be in line forever. Find a quiet station near your hotel to load up.
- Study the icons for your route. Don't try to remember "Constituyentes." Remember "the silhouette of the horse." It’s much easier to spot on a crowded platform sign.
- Avoid 8:00 AM and 6:00 PM. If you don't have to be somewhere, stay off the rails. The "Mexico City subway map" doesn't show the physical density of a thousand people trying to fit into a space meant for five hundred.
- Look up. The signs for transfers are color-coded and hanging from the ceiling. Follow the color of the line you want to reach. If you want the Blue Line, follow the blue ceiling tiles/signs.
Navigating this system is a rite of passage. Once you can navigate a transfer at Pino Suárez during a rainstorm without breaking a sweat, you’re basically a local. Just keep your eyes on the icons, your bag in front of you, and your 5-peso fare ready to go.
