Jericoacoara is a beach town that is generally considered safe, however, like any place, it's important to be cautious especially when you are traveling solo. The town is small and it's well-lit in the main areas, but some streets can be quite deserted at night. It's advisable to avoid those deserted areas and walk in groups when possible. Always remember to be vigilant and, as a precaution, don't carry high value items on you. Trust your gut feeling whenever you are unsure.
