Paso Colchane-Pisiga, Mountain pass at Chilean-Bolivian border in Tarapacá Region, Chile.
Paso Colchane-Pisiga is a mountain pass sitting at about 3,700 meters (12,100 feet) that connects Chile's Route 15-CH with Bolivia's National Route 12. The crossing point traverses high-altitude terrain with sparse vegetation and wide open views across both sides of the border.
The pass served as a trade route in pre-Columbian times when llama caravans moved goods between coastal and highland regions. This role as a connection point between different areas has continued through the centuries to the present day.
Indigenous communities in the area have adapted to life at the border while keeping their traditions alive. Their presence shapes how goods and people move through this mountain crossing.
The pass remains open year-round, but winter conditions can become difficult, especially with snow or ice. Visitors should prepare for possible border queue times and bring warm clothing since temperatures drop significantly at this elevation.
The pass forms part of a continental route linking Brazil with the Pacific Ocean by way of Bolivia and Chile. This connection places what appears to be a remote border crossing within a broader trade network spanning multiple countries.
