Located approximately 15 km from Salento is Valle de Cocora, which is part of the Los Nevados National Natural Park. The Valle is accessible by a 20 min jeep ride from Salento. Be prepared for the jeep to be packed with people, including them hanging off the back.
The Valle is home to the National Tree of Colombia the wax palm as well as several species of humming birds. There are several hikes around the Valle, with the most popular one taking an average of 5-6 hours to complete, which takes in these fantastic sites as well as rivers with bridge crossings. The trail does get quiet steep but the views (providing they not covered in clouds) are worth the effort.
