Teotihuacan lies about 50km north east of Mexico City, and for several centuries it was the largest city in the Americas and one of the largest in the world, with perhaps 125,000 people living on a planned grid. The most striking thing about it is not the size. IT IS THAT NOBODY KNOWS WHO BUILT IT. The city was already an abandoned ruin when the Aztecs found it roughly seven hundred years later, and the names we use are theirs: Teotihuacan, the place where the gods were created, the Pyramid of the Sun, the Avenue of the Dead. The builders' own name for the city, their language and their ethnicity are all unknown.

What Is Here
THE AVENUE OF THE DEAD IS THE SPINE AND IT IS LONGER THAN PEOPLE EXPECT. A ceremonial street running roughly two and a half kilometres north to south, lined with platforms, with the Pyramid of the Moon closing it at the north end and the Ciudadela at the south. Walking the whole axis and back is five kilometres on uneven stone at 2,300 metres with no shade. That one sentence is the entire packing problem of this destination.
THE PYRAMID OF THE SUN IS THE THIRD LARGEST PYRAMID IN THE WORLD, about 65 metres high on a base over 220 metres a side, and it is deliberately aligned on a grid that the whole city follows and that is tilted some 15 degrees off true north for reasons still argued about.
WHETHER YOU CAN CLIMB ANYTHING CHANGES, AND NO POST SHOULD PRINT A RULE THAT AGES. Access to the Sun and Moon pyramids has been opened, restricted and closed again at different times for conservation and crowd management, sometimes at short notice and sometimes partially. CHECK THE SITE'S OWN CURRENT NOTICE through INAH, the national institute of anthropology and history, in the week you travel, and build your day around what is actually open rather than around a photograph you have seen.
THE CIUDADELA IS THE SECOND IMAGE AND IT IS THE PART MOST VISITORS SKIP. A vast sunken square at the southern end enclosing the Temple of the Feathered Serpent, whose earlier facade, excavated behind the later one, carries rows of enormous stone serpent heads and goggle-eyed figures. It is the single best piece of sculpture on the site and it is a long walk from the car park, which is exactly why the coach parties miss it.
The carving in the third image is why you come close rather than only look up. The site is covered in relief and there are surviving painted murals, best at the Palace of Quetzalpapalotl near the Moon pyramid and in the Tepantitla compound outside the main enclosure, where the Paradise of Tlaloc fresco is.
THE BALLOONS AT SUNRISE ARE THE IMAGE AT THE TOP OF THIS POST AND THEY ARE A REAL DECISION RATHER THAN A TREAT. Flights lift from the fields west of the site at first light, when the air is still, and the view down the Avenue of the Dead with the pyramids throwing long shadows is the reason people do it. It is also an aviation activity in a country where oversight varies: BOOK AN OPERATOR WITH A VERIFIABLE PERMIT, ask about insurance before you pay rather than at the basket, and accept a cancellation for wind without arguing, because a balloon pilot who flies in marginal conditions to avoid refunding you is the problem. Flights go at dawn, which means leaving Mexico City around four in the morning or staying locally the night before.
The site museum and the botanical garden sit inside the enclosure near the Sun pyramid, and the museum's scale model is the clearest way to understand what you are walking through.
The vendors are persistent and the obsidian is real. This valley has been working obsidian for two thousand years and the stone is local, which makes a carved obsidian piece one of the few genuinely place-specific things to buy in Mexico. A firm no and walking on handles the rest.
When to Go
November to April is the dry season and the best of it, with clear mornings and warm days.
Be at the gate when it opens. The site is busiest from about eleven, the spring equinox brings enormous crowds, and the difference between eight and noon on the Avenue of the Dead is the difference between a long pleasant walk and an endurance event.
May is the hottest month before the rains and is genuinely hard going here.
June to September is the rainy season with heavy afternoon storms. Mornings are usually clear, the valley is green, and A STORM ON AN OPEN PLAIN WITH NO SHELTER IS A LIGHTNING RISK, so the site clears people off the high structures.
Balloon flights are cancelled for wind in any season and the cancellation rate is higher in the rains. Build a spare morning in if the flight is the point of the trip.
Getting There
By organised tour from Mexico City, which is how most visitors come and is the simplest option, usually leaving between seven and nine.
By bus, Autobuses Teotihuacanos run from the Terminal Central del Norte in Mexico City to the site gates, roughly an hour, frequently through the day. Ask for the PIRAMIDES service and note which of the site's five gates it uses.
By car, about an hour on the toll highway from the north of the city. There is parking at several gates.
THE SITE HAS FIVE GATES AND THEY ARE A LONG WAY APART. Entering at Gate 1 puts you at the Ciudadela end, Gate 2 and 3 near the Sun pyramid and Gate 5 near the Moon. Which gate you use decides what you see first and how far you walk, and a bus ticket or a taxi driver will not necessarily put you where you think.
Check opening days and conservation closures through INAH before travelling, because Mexican archaeological sites close on particular days and sections are fenced off for restoration.
Is Teotihuacan Safe for Women?
The site itself is a staffed, ticketed, busy enclosure and is safe. The FCDO does publish advised-against areas for Mexico, and being precise about them matters more here than almost anywhere, because the country is large and the restrictions are specific rather than general. It advises against all but essential travel to the cities of Tijuana and Tecate in Baja California, to the areas of Guanajuato south-west of road 45D, to most of the state of Michoacan with named exceptions for Morelia and Patzcuaro reached by toll road, to the parts of Jalisco south and south-west of Lake Chapala and eleven northern municipalities, to the state of Colima except Manzanillo reached by air or sea, to the state of Guerrero except Zihuatanejo and Ixtapa reached by air, to a 40km strip of the Guatemalan border in Chiapas, to one stretch of Federal Highway 199, and to the city of Acapulco. That last one appears on the safety and security subpage rather than in the landing page list, which is exactly why you should read both. None of those areas includes this destination. Read the current advice yourself before you travel, because the list is revised regularly.
THE ADVISORY RISK HERE ATTACHES TO THE JOURNEY RATHER THAN TO THE SITE, AND THAT DISTINCTION IS THE WHOLE OF IT. Teotihuacan is in the STATE OF MEXICO, not in Mexico City, and the FCDO's concerns for that state are armed robbery on public transport, vehicle theft on the highways and petty crime, which is precisely what the standard approach to this site involves: a bus out of a large terminal or a drive up a toll highway. The state carries no advised-against area. What follows practically is to travel in daylight, use first-class or named services rather than a roadside pickup, keep a bag on your lap rather than in an overhead rack, and not drive back after dark.
ALTITUDE AND SUN DO THE REAL DAMAGE. 2,300 metres with no shade anywhere on five kilometres of walking is how visitors come to grief here, and it is heat exhaustion and sunburn rather than anything else. The site has almost no trees and the stone radiates.
The stone itself is the second. Original stairways are steep, high-rise, worn round at the edges and without handrails, platform edges are unfenced above real drops, and the ground is uneven everywhere.
Street dogs are common around the gates and are generally indifferent, but give them space rather than food.
Mobile signal is patchy in parts of the enclosure, which matters if you have split up and arranged to meet.
The Teotihuacan Packing List
Five kilometres of stone, 2,300 metres, zero shade, and a dawn start if you fly.
Our merino base layers are 100% Australian merino at 17.5 micron, and a long sleeve merino wool base layer for women solves both ends of this day at once, which is unusual: it covers your arms through hours on bare stone at altitude where sunscreen you cannot reapply is the weak point, and it is also the layer you want standing in a field at five in the morning waiting for a balloon, when the valley is close to single figures. A cotton shirt is wrong for both.
A wide brim UPF 50 sun hat. ON A SITE WITH NO SHADE THIS IS THE MOST IMPORTANT ITEM, and a cap will not do, because what burns is the neck and the ears.
A long sun hoodie for the hottest months and a large insulated water bottle, because once you are out on the Avenue of the Dead there is nothing, and at this altitude in that sun you will drink more than you plan to.
Walking shoes with grip and Darn Tough merino socks: five kilometres of uneven original stone and steep handrail-free stairways, where sandals are how ankles go.
Not linked and worth packing: SUNGLASSES, which on pale stone at altitude are not a vanity; A LIGHT FLEECE for the dawn balloon field; CASH IN PESOS for the entrance, the gates and the vendors, since card acceptance at the ticket windows is not guaranteed; A SMALL DAYPACK, because you carry your own water for several hours; and NOTHING HEAVY, because everything you bring you carry two and a half kilometres and back.
Recommended Tours and Experiences
Essential Resources for Women in Teotihuacan
Emergency numbers: 911 for police, ambulance and fire, the single national number, free from any phone. English-speaking operators are available in the tourist states but are not guaranteed everywhere.
The risk on this trip is the journey rather than the ruins, and saying it that way round is the point: Teotihuacan is in the STATE OF MEXICO, which the FCDO names for armed robbery on public transport and vehicle theft on the highways while placing no advised-against area anywhere in it, and the normal approach to the site is exactly a bus out of a city terminal or a drive up a toll road. Travel in daylight, use named first-class services, keep your bag on your lap, and do not drive back after dark. THE SITE HAS FIVE GATES A LONG WAY APART and which one you use decides your whole walk. WHETHER THE PYRAMIDS CAN BE CLIMBED CHANGES: check the current INAH notice in the week you travel rather than trusting a photograph. THERE IS NO SHADE ON FIVE KILOMETRES OF WALKING AT 2,300 METRES, which is how visitors actually come to grief. ORIGINAL STAIRWAYS HAVE NO HANDRAILS and platform edges are unfenced. A BALLOON FLIGHT IS AN AVIATION BOOKING: use a permitted operator, confirm insurance before paying, and accept a wind cancellation. AN AFTERNOON STORM ON AN OPEN PLAIN IS A LIGHTNING RISK. CARRY PESOS.
US State Department travel advisory: the Mexico advisory. Read the current level there directly rather than relying on a figure printed in any guide.
UK FCDO travel advice: gov.uk/foreign-travel-advice/mexico, and read the safety and security page rather than only the landing page, because that is where the substance sits.
Main hospital or clinic: there is first aid at the site and a small hospital in San Juan Teotihuacan, the town beside it, for routine matters. Anything serious means MEXICO CITY, about an hour away, which has the best public and private hospitals in the country, so the medical position here is good by the standards of this batch provided you are not relying on the local clinic for something major. Private facilities expect payment or a direct insurance guarantee up front. Dial 911, and if something happens out on the Avenue of the Dead, send someone to the nearest gate rather than relying on a phone, because signal inside the enclosure is patchy and the staff there can direct an ambulance to the right entrance. Private hospitals in the large Mexican cities are good and expect payment or a direct insurance guarantee up front, so carry your policy number where you can reach it rather than in the bottom of a bag. Public clinics will treat an emergency. Tap water is not drinkable anywhere in the country: drink bottled or purified water, which every hotel and restaurant supplies as a matter of course, and take the same care with ice and raw salad that you would with the water itself.

Takeaways
Nobody knows who built it. The names are all Aztec, seven centuries later.
Be at the gate when it opens, and walk south to the Ciudadela. Most people never get there.
Check the INAH notice for what is climbable. It changes.
No shade, five kilometres, 2,300 metres. The hat matters more than the camera.
Solo women safety assessment: Teotihuacan is straightforward to do alone and most visitors effectively are, because you arrive on a tour or a frequent public bus and spend the day inside a staffed, ticketed, busy enclosure with site guards, a museum, shops and a steady flow of people from mid-morning. There is no quarter to avoid and nothing about the site that calls for special caution. The social friction is persistent vendors, which a firm no and walking on handles. THE PART WORTH PLANNING IS THE JOURNEY, and the honest framing is that the advisory risk belongs to the road rather than to the ruins. The site is in the State of Mexico, which the FCDO names for armed robbery on public transport and for vehicle theft on the highways, while placing no advised-against area anywhere in the state, and the standard approach is precisely a bus from a large city terminal or a drive up a toll highway. So travel in daylight, take a named first-class or dedicated Piramides service rather than a roadside pickup, keep your bag on your lap instead of in the rack above you, use an app taxi or a sitio rather than a street cab at either end, and do not drive back to the city after dark. 911 IS THE NATIONAL EMERGENCY NUMBER, Mexico City's hospitals are an hour away and are the best in the country, and the local clinic in San Juan Teotihuacan handles routine matters only. One specific point: MOBILE SIGNAL INSIDE THE ENCLOSURE IS PATCHY and the site is enormous, so if something goes wrong the fastest help is the nearest of the five gates rather than your phone. WHAT ACTUALLY INJURES PEOPLE HERE IS SUN AND STONE. There is no shade on five kilometres of walking at 2,300 metres, the original stairways are steep and worn with no handrail, and the platform edges are unfenced above real drops. A hat, covered arms, more water than you think, grippy shoes and an eight o'clock start are the whole of the answer. If you book a dawn balloon flight, treat it as an aviation purchase: a permitted operator, insurance confirmed before you pay, and a wind cancellation accepted without argument.
Reading On
Teotihuacan is a morning out of the capital. The Mexico City packing list covers the city you will stay in, its altitude, its metro and its neighbourhoods, and is the natural companion to this post. For the other great pre-Hispanic sites in this library, the Monte Alban packing list covers the Zapotec capital on a levelled mountain above Oaxaca, the Cholula packing list the largest pyramid by volume in the world with a church built on top of it, the Uxmal packing list the Puuc Maya city in the Yucatan and the Palenque packing list the Maya city in the Chiapas jungle. Nearby, the Puebla packing list and Atlixco packing list cover the volcano country south east, and the Queretaro packing list and Bernal packing list the Bajio to the north. South, the Oaxaca packing list and Hierve el Agua packing list. For the country, the Mexico travel guide for women and the Mexico packing list carry the transport and the advisory geography in full. For why covering up beats cooling down at altitude, read the guide to merino wool base layers for women. Every destination we cover is indexed at the travel packing guide for women, and the base layers are at the Roman Trail collection.
