PNN El Cocuy is a national park. It is public land! It overlaps with an indigenous reservate, which also is public land. Nothing in this park is closed. All hiking trails pass through a wilderness, moutaineous part of the park, where NOBODY lives.
This has nothing to do with people passing through private property. It is a historic and religious matter why the indigenous do not like people passing through these lands.
Compare it to some mountain summits in the world which are considered to be holy and where local people do not want humans to set foot on it.
