:Ovalle Punitaqui Combarbala, Salamanca, Cabildo, Putaendo, Santiago

Extremely demanding route, featuring an 11 km stretch of dirt and sand climbing starting from Punitaqui. From there to Combarbalá, the surface is oily dirt. From Limahuida to the Las Palmas tunnel, it's pure gravel and sand with three 10 km climbs plus the Las Astas, Recto, Curvo, Las Palmas tunnels, with the latter containing water inside. The La Grupa tunnel has a traffic light to indicate the direction of the small transit (6 minutes per side). It is an extreme, dangerous, and purely adventurous route. Completed in 2009.
