It is completely normal to feel a bit nervous before a first visit to Mexico City. It is one of the world’s largest cities, and there is a lot of conflicting advice out there. Most of it is either too cautious or too vague to be useful.
What we see, consistently, is that first-time visitors to Mexico City do not get tripped up by the things they worry about most. They get tripped up by the things nobody thought to mention. This article is about those things.
Staying in Centro Histórico Because It Looks Impressive on a Map
What people do: Book accommodation in Centro Histórico because it is central, historic, and full of recognisable landmarks.
Why it is a problem: Centro is genuinely impressive during daylight hours. At night, it gets dicey fast. Petty theft, street crime, and poorly lit streets make it uncomfortable to walk around after dark, even in groups. Dozens of recent Reddit posts from 2024 and 2025 flag this specific issue. Beyond safety, Centro feels disconnected from the CDMX that locals actually inhabit. It is touristy in the way that makes a city feel smaller than it is.
What to do instead: Stay in Roma Norte, Condesa, or Coyoacán. These are the neighbourhoods where young Mexicans live, where independent cafes and galleries concentrate, and where the city’s actual energy lives. They are safe to walk around in the evening, easier on the budget (accommodation runs $60-120/night versus $150+ in Centro, as of 2026), and dramatically better for eating well without overpaying. You can always take the Metro to Centro for the day and leave before dark.

Ignoring the Metro Because It Sounds Intimidating
What people do: Default to Uber for everything, treating the Metro as a last resort.
Why it is a problem: The Mexico City Metro costs about $0.30 USD per ride. It is modern, well-maintained, and covers virtually every part of the city you will want to visit. Uber works in CDMX, but surge pricing at night can reach three to five times the base fare. By the end of a week using Uber exclusively, visitors have spent $80-150 more than they needed to.
What to do instead: Use the Metro for daytime travel. It is fast, cheap, and straightforward. Google Maps handles Metro routing well, even if you do not read Spanish. Pick up a Tarjeta de Viaje (reloadable travel card) at any station. After 9-10pm, switch to Didi or Uber for safety and convenience.
One thing worth knowing: Didi, the Chinese ride-hailing app, operates in Mexico City and is consistently cheaper than Uber. Locals use it far more. Download it before you arrive.
Not Knowing About Didi
This one comes up constantly in traveller forums and almost never makes it into mainstream guides.
Most visitors land in CDMX with Uber installed and assume that is the local ride-hailing option. It is not the preferred one. Didi entered the Mexico City market aggressively, undercuts Uber on price by 20-30%, and has less severe surge pricing at night. A short daytime ride that costs $8 on Uber might be $5-6 on Didi.
The catch: Didi requires a phone number to register, and ideally a Mexican one. If you are getting an eSIM for the trip (recommended), set up Didi once you have a local number. You can also register with a foreign number and sort it out over hotel WiFi before your first ride.
Paying $60 for an Airport Transfer
What people do: Book a pre-arranged hotel transfer or Viator pickup for $40-80 USD, because arriving in a new city feels like the wrong moment to figure out public transit.
Why it is a problem: The airport sits about 8km east of the city centre. The Metro runs directly from the terminal. Two rides on the Metro (airport to transfer point, transfer to your neighbourhood) cost under $1 combined.
What to do instead: During daylight hours, take the Metro or book a Didi in advance. A Didi or Uber from the airport to Roma or Condesa runs $15-20 USD during the day. If you are arriving late at night (after 10pm), surge pricing can push that to $35-45. In that case, a pre-arranged transfer makes more sense. But for a daytime arrival, the $60 hotel transfer is pure overpayment.
Booking Frida Kahlo Without Checking Availability First
What people do: Assume major museums in Mexico City work like most attractions: show up, buy a ticket, go in.
Why it is a problem: The Museo de Frida Kahlo (La Casa Azul) operates on timed entry and sells out 3-5 days in advance during busy periods. Visitors who arrive hoping to buy tickets at the door in peak season routinely find the day fully booked. The loss is not just the experience; it is also a half-day of planning that falls apart.
What to do instead: Book Frida Kahlo tickets online before you leave home. Tickets cost $16-18 USD via the official website or Ticketmaster Mexico. The 10am slot is the most popular and fills first; early afternoon is usually easier to secure. This is one of a small number of genuinely non-negotiable advance bookings in CDMX.
Museo Templo Mayor has queues but moves reasonably quickly. Palacio de Bellas Artes is generally walk-in friendly.
Scheduling CDMX Like a Small City
What people do: Build an itinerary that packs five or six things into a single day.
Why it is a problem: Mexico City has a population of around nine million people, and the areas visitors want to see are spread across a huge geographic footprint. Getting from Roma to Coyoacán takes 40-50 minutes. Getting from Coyoacán to Xochimilco takes another 20-30. A day with Templo Mayor, Frida Kahlo, lunch in Coyoacán, and an evening in Condesa sounds manageable on paper. In practice, it means spending half the day in transit, rushing through everything, and arriving back at the hotel exhausted.
Map
What to do instead: Plan by neighbourhood. Give yourself 2-3 things per area per day, maximum. CDMX rewards slow movement. The cafes, street food stalls, and side streets between landmarks are often the best parts.
Visiting Xochimilco on a Weekend
What people do: Schedule the floating gardens on a Saturday or Sunday because it fits their itinerary.
Why it is a problem: Xochimilco on a weekend is genuinely overwhelming. It is choked with visitors, Mexican families on group outings, and boats blasting music at each other. The experience is loud, crowded, and nothing like the serene canal experience most people have in mind when they book it.
What to do instead: Go Monday through Thursday, arrive before 11am, and consider a private trajinera (boat) rather than the shared group option. Private boats run $80-120 USD for a group of four and give you the chance to actually hear yourself think. The canals are legitimately beautiful when you can experience them without the weekend chaos.
Making Common Money Mistakes
ATM fees: Most visitors use their home bank card at the first ATM they see, often inside the airport, and pay $5-8 USD in combined fees per withdrawal. In practice: use ATMs attached to major banks (BBVA, Santander, Banamex), decline the dynamic currency conversion offer (always choose to be charged in pesos, not your home currency), and withdraw larger amounts less frequently to minimise per-transaction fees.
Currency exchange: The street-level exchange booths you see near major tourist areas typically offer 10-15% worse rates than ATMs. The airport exchange desks are worse still. Use your bank card at a reputable ATM.
Tipping norms: Tipping in Mexico City is expected in sit-down restaurants (10-15% is standard, 20% appreciated for excellent service), with taxi and Didi drivers for long rides, and in nicer hotels. At street food stalls and taquerías, it is appreciated but not required. Carry small-denomination pesos for this: 10 and 20 peso coins are useful.
Misreading the Altitude
This is the one that catches people genuinely off-guard, and it almost never appears in mainstream guides.
Mexico City sits at 7,350 feet above sea level. That is higher than most people realise. For visitors arriving from sea-level cities, the first 24-48 hours can bring headaches, unusual fatigue, and shortness of breath during mild activity. Most visitors attribute this to jet lag or the journey and push through a packed first day, which makes it worse.
Worth knowing: build a lighter first day into your itinerary. Walk around your neighbourhood, eat well, drink more water than usual, avoid alcohol on the first evening. By day two, most people have adjusted and feel fine. It is not a medical emergency for healthy adults, but it is a real physical adjustment that affects your energy and mood.
Skipping the Neighbourhoods That Are Not on the Standard Circuit
This is the mistake that changes the whole trip when people realise they made it too late.
What people do: Follow the standard museum-and-landmark circuit: Templo Mayor, Bellas Artes, Frida Kahlo, Xochimilco. All worth doing. None of them show you why people who visit Mexico City once come back five times.
Why it is a problem: CDMX has extraordinary neighbourhoods that most first-time visitors never reach. San Ángel on a Saturday morning, with its Bazar del Sábado craft market and colonial streets, is one of the best experiences in the city. Colonia Roma’s side streets have the kind of independent bookshops, specialty coffee, and neighbourhood restaurants that cities like this one are known for. Coyoacán’s central plaza on a weekend afternoon, with musicians and locals sitting under the trees, is exactly what people picture when they think of Mexico.
What to do instead: Build at least one full day around a neighbourhood with no specific attraction at the end of it. Walk slowly. Eat where locals are eating. Mexico City rewards that kind of exploration more than almost any other city its size.
The One Thing Everyone Wishes They Had Known
Mexico City has one of the best street food scenes on earth. Not “good for a capital city” or “surprisingly good.” Genuinely one of the best. The tacos, tlayudas, quesadillas, tamales, and esquites available from street stalls and market stands cost $1-3 USD and are frequently better than sit-down meals that cost ten times more.
Here is the thing: most first-time visitors spend the first three days eating at restaurants because street food feels like a risk. By day four or five, they start trying it. And then they spend the rest of the trip mildly devastated about the time they wasted.
The rule of thumb from experienced CDMX visitors is straightforward. A stall with a crowd of locals around it at lunchtime is safe. Full stop. The volume of daily diners means the food is fresh, the turnover is high, and the sanitation is better than you might assume. Start earlier than you think you need to. The street food here is not a side note to the trip. It is the trip.
Quick Pre-Trip Checklist
Before you land in Mexico City, sort these:
- Visa requirements: Citizens of the US, UK, Canada, and most EU countries do not need a visa for tourist stays under 180 days. Check current requirements on the Mexican government’s immigration portal as rules can update.
- Currency: Mexican pesos (MXN). Bring $100-200 USD in cash as backup, but plan to use ATMs at major banks in the city. Decline dynamic currency conversion at all times.
- Apps to download: Didi (ride-hailing, cheaper than Uber), Google Maps (includes Metro routing), WhatsApp (standard communication in Mexico).
- Key bookings to make before you leave: Frida Kahlo Museum timed entry (book 3-5 days minimum before your visit), any popular restaurants for weekend dinners.
- Accommodation: Book in Roma Norte, Condesa, or Coyoacán rather than Centro Histórico.
- Travel insurance: Worth having before any international trip. SafetyWing offers flexible coverage that works well for city travel and longer stays.
- Altitude: If you have heart or respiratory conditions, consult your doctor before visiting. For healthy adults, just plan a lighter first day.
