It's not crazy unsafe but I would recommend anyone travelling to do your research. Walk with caution, don't bring out flashy jewellery or be relaxed with your cellphone or cameras. During the day there's plenty of people out and police. But the night can get tricky around certain areas.

Depends on the area, but from my point of view and personal experience, it is generally safe. You should maybe be careful at night. Common delinquency could be an issue downtown, but if you are carefull it should be fine.

Pereira is not a very big city and overall I feel safe walking alone, but you have always to be careful where are you going, some neighbors are safer than others and also what time of the day you are out. Areas with bars and businesses open after dark are generally safe. I do not recommend walking alone at night in alone streets
