What to know before travelling to Mexico (City)
Before visiting one of the world’s largest and most fascinating capitals, there are a few important things to know before travelling to Mexico City. From its remarkable history and unique geological foundations to its high-altitude location and practical safety considerations, a little preparation can go a long way. Understanding these key aspects will help you navigate the city with confidence and make the most of your experience.
In this guide, you’ll discover why Mexico City is often referred to as “the sinking city,” learn how the city’s altitude may affect your body, and find practical tips for preventing altitude sickness. Additionally, we’ll share essential safety advice and local insights to help you enjoy a smooth, memorable, and worry-free trip to Mexico’s vibrant capital.
One of the most surprising things to know before traveling to Mexico City is that parts of the city are literally sinking.
The reason lies in the city’s fascinating history. Modern-day Mexico City was built on the site of Lake Texcoco, a vast lake that was gradually drained after the Spanish conquest to allow for urban expansion. Although the lake disappeared, the soft, water-saturated soil beneath the city remained.
As a result, much of the city still rests on former lakebed sediments that have been compressing for centuries. Consequently, buildings, roads, and infrastructure slowly sink into the ground each year. In some areas, the effects are clearly visible, with leaning buildings, uneven sidewalks, and cracked streets providing a striking reminder of the city’s unique foundations.
While this phenomenon does not affect daily travel plans, it is certainly one of the most interesting facts about Mexico City and helps explain why the city’s architecture and infrastructure require constant maintenance and adaptation.
Another important thing to know before traveling to Mexico City is its elevation.
Mexico City sits approximately 2,200 meters (7,200 feet) above sea level and is surrounded by spectacular mountain ranges, some of which rise to over 5,000 meters (16,400 feet). Because of this high altitude, some visitors may experience mild symptoms of altitude sickness during their first days in the city.
Common symptoms can include headaches, fatigue, shortness of breath, dizziness, or difficulty sleeping. Fortunately, most travelers adjust quickly. However, it is a good idea to take things slowly when you first arrive.
For example, consider scheduling less demanding activities on your first day, drinking plenty of water, and avoiding excessive alcohol consumption. In addition, getting enough rest can help your body adapt more comfortably to the thinner air.
Once acclimatized, most visitors have no problems exploring the city’s many attractions, museums, markets, and historic neighborhoods.
Safety is often one of the biggest concerns when planning a trip. Fortunately, millions of tourists visit Mexico City every year and enjoy a safe and memorable experience. Nevertheless, like in any large metropolitan area, it is important to stay aware of your surroundings and follow some basic precautions.
Here are our top safety tips for traveling to Mexico City:
- Avoid visiting neighborhoods that are known for safety concerns, especially after dark.
- Whenever possible, plan your itinerary so that you arrive at new destinations before sunset.
- Use ride-hailing services such as Uber, particularly at night or when traveling longer distances.
- Keep valuables such as cameras, smartphones, passports, and large amounts of cash out of sight.
- Consider carrying only the money and cards you need for the day.
- Leave expensive jewelry and luxury accessories at home whenever possible.
- Stay alert in crowded tourist areas, public transportation hubs, and busy markets.
- Most importantly, trust your instincts. If a situation feels uncomfortable or unsafe, it is usually best to move on or leave the area.
By taking these simple precautions, you can significantly reduce potential risks and focus on enjoying the incredible culture, food, history, and hospitality that make Mexico City such a rewarding destination.
