Carretera 37 is a mountain road located in southern Colombia with a length of 196 km (121 miles), going within the foothills of the Cordillera Central.
The road is paved, but includes very narrow parts on sand/gravel sections. It’s located near the National Archeological Park of Tierradentro, with stunning views of the Nevado del Huila volcano. This serpentine road links Garzon, a town and municipality in the Huila Department and Corinto, a town in the Cauca Department.
2019 Update: The road is closed due to drug cartel fightings. It’s probably blocked since 2018.
