Colombia would prioritize security measures in historically violent regions to prevent the possible interference of illegal armed groups.
The municipalities in historically violent regions were prioritized because  they have some kind of risk caused by illegal armed groups. The government prioritized 99 of 1,300 municipalities for “electoral risk” posed by illegal armed groups. Fifty unidentified municipalities would be facing a “Priority Risk.” The remaining 49 would be facing a lower level of risk that merits extra attention. Protests and rallies may also occur around elections or on commemorative days.

Reconsider your need to travel to the departments of Antioquia (except Medellín), Arauca, Caquetá, Cauca (except Popayan), Chocó (except its capital Quibdó and the whale-watching towns of Nuqui, Bania Solano and Capurganá), Guainía, Guaviare, Meta, (except Villavicencio and the tourist site of Caño Cristales), Nariño (except Pasto and the border crossing of Ipiales), Norte de Santander, Putumayo, Valle de Cauca (except Cali) and Vichada, due to the high threat of terrorism and criminal activity.

Avoid non-essential travel. Do your research and check that your insurer will cover you. If you do travel, take extra precautions to protect yourself from security and health risks. Monitor the media and follow the advice of local authorities.
