Arauco, Coastal city in Bio Bio Region, Chile.
Arauco is a coastal city in the Bio Bío Region that stretches along the Pacific shore surrounded by forests and wetlands. The municipality features a wide sandy beach and sits at low elevation right by the ocean.
Pedro de Valdivia established Fort San Felipe de Arauco in 1552, marking the start of Spanish colonial presence in this strategic location. This founding shaped the territory's development during the centuries that followed.
The name Arauco comes from the Mapudungun word 'ragko', meaning chalky water, and this indigenous heritage remains visible in local traditions and how residents connect with the surrounding lands. The place carries the history of the Mapuche people who have long inhabited this coastal region.
The city connects to major Chilean cities through multiple routes, making it accessible for visitors. The surrounding forests and wetlands offer trails for walking and nature exploration near the coast.
The local wetlands provide habitat for more than 100 bird species, especially during the warmer months. This variety makes the place an unexpected haven for those interested in observing birds.
