Never Drink Tap Water

When in Cancun, or anywhere else in Mexico, never drink the tap water. Unfortunately, the tap water is not clean and can make you very sick. When eating out in more popular locations, you don’t have to worry that you’ll be served unfiltered water. But if you are in more remote areas, always ask if the water is filtered and if the ice they provide in their drinks is filtered as well. The worst thing to happen is that you get sick during your trip and you spend the rest of your days on vacation inside your hotel bathroom rather than outside enjoying the sun, the sand and the pristine blue waters.
