Cuba is one of the safest countries in the world for women to travel in. Sexual assault of any kind is practically unheard of, and women are typically free to go wherever they want, whenever they want, without worry. That being said, always use good judgment and take standard precautions, such as taking a friend with you, if you’ll be out very late. Occasionally, women will receive unwanted attention or catcalling when walking by groups of local men. The best thing to do is walk by without engaging with them or making eye contact.
