Encenillo Biological Reserve isin Trinidad in the province of Guasca about an hour out of Bogotá. It was established in 2007 with the purpose of conserving forests and preserving some of the unique species of birds and plants of Colombia.
This is the last remnants of primary forest of the Eastern Andean Cordillera. It had trees and plants like certain species of orchids and cedars not found anywhere else. This may be the last refuge of populations of species of birds and mammals such as gouache and armadillo in the area.
It was also an area for limestone and you can see many quarries on route. Thiis is a regenerated quarry. There are many different hiking trails and excellent guides if you speak Spanish. For more info go to http://travelwellflysafe.com/2014/05/03/day-trip-from-bogota-colombia/
