Before you hop on a flight to Mexico, you’ll need to know about the country’s entry requirements for UK nationals.
The good news is that you don’t need a visa to enter Mexico as a tourist from the UK. You can stay in the country for a maximum of 180 days without a visa.³
You’ll just need to make sure your passport is valid for the duration of your stay. Ideally, it will have 6 to 12 months remaining - as this is what most countries require.
On entering Mexico, you’ll get a stamp in your passport with the number of days you’re allowed to stay.
Other things you need to know about entry requirements for Mexico:³
Many parts of Mexico are generally considered to be safe for tourists and foreign visitors, provided you take sensible precautions to ensure your safety. We’ll cover some safety tips, including emergency contact information, later in this guide.
However, some cities and states in the country are best avoided for safety reasons. The UK Government’s Foreign, Commonwealth and Development Office (FCDO) advises all but essential travel to the following areas:¹
Flight times from the UK to Mexico vary depending where you’re travelling to and from.
But to give you an idea, the flight time between London Heathrow Airport and Mexico City is 11 hours and 35 minutes.² This is for a direct flight, although some routes will have at least 1 stop.
It’s always a good idea to read up on health information when visiting a foreign country. The last thing you want is for your dream trip to be ruined by illness, or because you’re turned away at the border for not having the right vaccinations when travelling to Mexico.
According to Travel Health Pro, travellers to Mexico should ensure they are up-to-date with vaccinations for hepatitis A, tetanus and typhoid.⁴ This is in addition to the usual vaccines required for UK travellers.
There is also a risk of malaria and dengue in Mexico,⁴ so you should take all preventative measures possible to avoid mosquito bites. And make sure you’re aware of the symptoms of both illnesses.
Other health tips for Mexico include:
We’ve looked at health advice for Mexico, but it’s also important to think about how you’ll stay safe during your trip. Here are some tips to remember:
If you experience an emergency situation during your trip, here are the numbers to call:⁵
Make sure you have the number of your travel insurance provider too, in case you need to make a claim or seek assistance.
If you’re planning on travelling around the city you’re visiting or even different parts of the country, it’s useful to know about Mexico’s public transport system.
Buses are by far the most popular way to travel between towns and cities, and they’re usually pretty cheap too.
In major cities like Mexico City, you’ll have a choice of buses, subway and even cable cars to help you get around.
If you’d prefer to explore Mexico by car, there are plenty of places you can hire one. Popular companies include Avis, Hertz, Europcar and Sixt, along with local options such as Localiza and America Car Rental.
To hire a car in Mexico, you’ll need your UK driving licence, your passport or other form of valid photo ID and a debit/credit card. Many car hire companies also charge a premium for drivers who are under the age of 21-25.⁶
It’s always recommended to brush up on local rules, laws and customs in the country you’re visiting. If the culture is different to what you’re used to back in the UK, you may inadvertently fall foul of the rules and end up in trouble with the law.
Here are some of the local laws you need to know about in Mexico:⁷
In terms of customs and cultural differences, tipping is common and expected in Mexico. A tip of around 10-15% of the bill will be appreciated.⁸
Spanish is by far the most common language spoken in Mexico. But there are actually around 63 indigenous languages recognised by the Mexican government.⁹
You’ll find English spoken in tourist areas and in some parts of major cities. But it could be worth learning a few key phrases in Spanish just in case.
Now, you’ll need to know the best way to spend while in Mexico, as well as how to manage and convert your money.
The first crucial thing to know is the official currency, which is the Mexican peso (MXN). Confusingly, the symbol is $ - just like the US dollar. It’s sometimes written as M$, MX$ or MEX$ because of this.
You can change your pounds for pesos here in the UK, or when you arrive. Just make sure to check the exchange rate and fees, to make sure you’re getting a good deal. It’s best to avoid changing currency in airports or hotels, as they are notorious for offering very poor deals in exchange for the convenience they offer.
Spending on a debit or credit card is also an option - you’ll just need to check whether your bank or card provider charges fees for spending in foreign currencies.
Mexico is quite cash-centric, although cards are accepted in many major towns, cities and tourist areas. You’ll find plenty of ATMs in Mexico, usually located in shopping centres, main streets, central plazas and outside Mexican banks.
Just be careful when using them, as it’s not unheard of for foreign tourists to be targeted by thieves at ATMs. Only withdraw cash in the daytime, choose a public place and have someone with you.
You may also want to avoid withdrawing large amounts, to make yourself less of a target. And make sure you get a money belt to wear under your clothes - it’s the safest way to carry cash around, keeping it out of the reach of pickpockets.
