There are some truly remarkable treks possible in this region, from hikes of a few hours into cloud forest to 5-day treks to the base of snow-capped mountains, and beyond!

Salento, is one of the better destinations in Colombia for trekking in terms of infrastructure. There are reasonably well marked trails and occassionally some signposting, although it is still quite easy to get lost.
For this reason, I strongly recommend not going alone unless you’re just planning on strolling around the lower valley.
