Frequently Asked Questions
You should drink bottled water, which is easily available throughout Guadalajara, or boil your water for approximately 30-40 minutes. After brushing your teeth, rinse with bottled water, and don't open your mouth when taking a shower. You should also be careful of handling money and then handling your food. Like anywhere, the money is very dirty so always wash your hands before touching your food.
No, you don't. But we recommend that you check on the Mexican Embassy's website for your country for recommendations. Traveling to large, major cities in Mexico isn't a problem. Traveling to Guadalajara will certainly not require a vaccine. There may be some need to get vaccines if traveling to tropical areas, or areas where outbreaks have occurred before; these are usually places that are distant from civilization and not frequented by travelers. So, you shouldn't need a vaccine if staying in the city.
Citizens of the United States or Canada who are planning a trip to Mexico will need to carry a passport or WHTI-compliant travel document. A passport is necessary for everyone entering Mexico by air. Travelers entering Mexico by land may not be asked to present a passport, but will need to present one upon return to the US or Canada, so be sure you have it. The passport requirement is waived in some cases for minors, notably, school groups that are traveling together. Since requirements vary from country to country, the best thing will be to contact your nearest Mexican consulate and inquire with them.
