The area's páramo ecosystem is a rare glacier-formed tropical zone that exists between 3000m and 5000m in the mountains. It's characterized by lakes and plains rich with peat bogs, and wet grasslands mashed with shrub lands and forest patches. Páramo only exists in a few countries in the world, with a large portion of it in Colombia. As in Parque Nacional Natural (PNN) El Cocuy to the north, where the páramo also thrives, there are excellent trekking opportunities here.
