Amazonia is the rainforest region in the south of Colombia.
You might assume that the remote jungle lands of Colombia might be the refuge of the FARC, but the fact is that much of it is too remote for even guerillas to operate. The extreme south is very safe (aside from natural dangers like snakes and mosquitos!), and visitors should not worry about violence on a trip to Leticia and the Amacayacu National Park. Western Putumayo, however (the extreme west of the region), is a hotbed of guerilla activity.
