In the upscale resort area of the Riviera Maya, crime rates are exceptionally low. However, if you plan to travel independently through the roads of the Yucatán, exercise caution. Avoid carrying large sums of money, dressing provocatively, or wearing conspicuous jewelry and ornaments. It's also advisable to refrain from walking alone at night. Prior to setting out, inform someone you trust about your whereabouts and purpose.
Another precaution to take is to insist that alcoholic beverages and other drinks be prepared in front of you at entertainment venues. There have been instances of drinks being spiked with drugs for the purpose of theft.
To protect your financial information, avoid using credit cards at remote ATMs, gift shops, or other dubious locations to reduce the risk of card fraud.
