South of Santiago and north of the Carretera Austral, this route links the Panamerican in Chile to Ruta 40 in Argentina via a low-traffic dirt pass. Alternatively, anyone wanting to return immediately to Chile via a potential hike-and-bike pass could skip Ruta 40 and turn off from El Cholar south towards Copahue, dropping back into Chile in Araucania.
Leaving Los Angeles in Chile, look left and right along the paved road as you steadily climb past a commercial logging forest. The trees branching out in the main plaza in Antuco offer up a resting place in the central valley heat. A few kilometers later, the pavement ends as you approach the Parque Nacional Laguna de Laja. Enter the park, and the road ramps up, bringing you to a slightly sandy washboard road along la Laguna de Laja, with snow-capped peaks rising up in the distance. Roadside memorial plaques and flags bear witness to the Tragedy of Antuco, when in 2005 45 Chilean soldiers died in a sudden blizzard during training manoeuvers on Volcán Antuco. The Chilean immigration office waits at the end of the park, and seems to see little traffic of any kind.
45km of No Man’s Land lies between Chilean and Argentinean immigrations, cut through by Paso Pichachen. Nice camp opportunities abound in between, with huasos and guachos out to keep you company. The Chilean climbs tend to be steeper than in Argentina.
Water is readily available from Los Angeles to El Cholar. From El Cholar in Argentina, the options to continue are to head east to Ruta 40 near Chos Malal, or head south to Copahue and cross back into Chile via a hike-n-bike pass. Little water is available between El Cholar and Chos Malal.
This route goes from VIII Region de Biobio (Chile) to Neuquen (Argentina).

|0km||100m||Los Angeles (GPS01). Large town with accommodation, shops, restaurants, ATM.|
|~25km||>100m||Starting ~25km out of Los Angeles towards Antuco, road is lined on both sides by pine forests, looked to be for commercial logging. Forest is fenced off by barbed wire, but there are enough breaks or places to duck under that it would be a nice option to camp instead of staying in Los Angeles. Forest continues a significant distance towards Antuco.|
