I'm starting to think about my 2026 trip, and was looking at joining a group tour in Colombia, going as a solo traveller. However, there would be some free afternoons in Bogota, Medellin and Cartagena so I would be going off on my own some of the time. I suppose I just want to get a handle on how safe this is for a lone woman? I'm not an especially nervous traveller and as a slightly fat middle-aged woman I've never suffered from being hassled. But I am aware that Colombia has had a reputation for street crime, even though it's vastly safer than it used to be, and I want to be realistic about how much I'll be able to see by myself. Anyone been, especially alone?
