Montenegro in Colombia might be a relatively peaceful area, but it's still important to remain vigilant and careful. Although it may not be particularly rife with crime or danger, street crime such as muggings and pickpocketing is not unheard of.

Being cautious with food and water is also necessary to avoid waterborne diseases.
