Carretera 37 from Garzon To Corinto. Asphalted road that includes very narrow parts on sand and gravel surface. 196 km (121 miles) within the foothills of the Cordillera Central and very close to National Archeological Park of Tierradentro. Stunning views of the Nevado del Huila volcano. You better regard this road as Off-Road though we mention it as Tarmac.
