Ensure that you have all the necessary documentation to enter the country before travel. This includes a passport that is valid for at least six months from your planned date of arrival in Mexico. You will also need to obtain a Tourist Card, otherwise known as a Migratory Tourist Form (FMT). While visas are not required for tourists entering Mexico (depending on your country of origin), you will be asked to fill out an immigration form which is a requirement for obtaining a Tourist Card. Alternatively, the card can be obtained beforehand from your nearest Mexican embassy or consulate.
Purchase a travel insurance plan before you leave. Travel insurance will protect you in the event of illness and travel disruptions. Insurance coverage will also compensate you for lost or stolen belongings.
Visit your doctor before you travel and tell him or her where you plan to travel in Mexico and for how long. According to the National Travel Health Network and Centre, certain areas in Mexico present elevated risks for diseases like malaria, hepatitis A and B, rabies, typhoid and tetanus. Your doctor will be able to provide you with up-to-date information on health considerations as well as provide you with any necessary vaccines or medications.
Contact the U.S. State Department (or Foreign Office in the United Kingdom) before you leave to check whether it is considered safe for tourists to travel to Mexico. These agencies provide information concerning areas in Mexico where travel is strongly advised against. They can also advise you about the prevalence of recent events relating to drug-related crimes, kidnapping, violence against tourists, terrorism and any other safety issues which may be relevant at the time.
