Chaitén is in Los Lagos region in the south of Chile. The town has an important transportation hub on the Carretera Austral with major ferry services to Chiloé and Puerto Montt.
Chaitén sits at the natural break‑point where the famed southern highway pauses before plunging into the remote interior. This makes the town the de‑facto staging post for travellers intent on tackling the rugged stretches towards Puerto Río Tranquilo or Villa O'Higgins. While most guidebooks note the highway’s existence, few stress the practicalities: a modest parking area for overland rigs, a handful of reliable diesel pumps, and a cosy refectory where long‑haul drivers swap stories over smoked trout. The town’s proximity to the Yelcho estuary also offers a calm launching point for day‑long kayak trips into the Gulf of Corcovado, a quiet counterpoint to the busier ferry routes further south.
The 2008 eruption forced an evacuation that emptied Chaitén, yet the town’s rebirth showcases a distinctive Chilean resolve. Reconstruction has been guided by local input, with new homes built on stilts and flexible foundations to mitigate ash loading. Community gardens sprout on reclaimed land, supplying fresh produce and fostering a sense of ownership rarely seen in post‑disaster rebuilds. Visitors who linger beyond the surface can attend a voluntary workshop at the municipal centre, learning about the ash‑filtering techniques residents employ in daily life. This pragmatic adaptation provides a rare glimpse into how a remote settlement negotiates the ever‑present geological risk while retaining its coastal character.
While most travel narratives skim over the Desertores Islands, they merit a separate mention for their unspoiled biodiversity and low‑key fishing culture. Small boat tours depart from Chaitén’s modest pier, ferrying guests to islands where sea‑lion colonies mingle with kelp forests, and where a solitary lighthouse marks centuries of maritime navigation. The islands lack tourist infrastructure, meaning a visit is more akin to a field study than a leisure cruise; supplies are limited, and visitors must bring their own provisions. This modest isolation offers a rewarding contrast to the mainland’s busier ports, rewarding those who value quiet observation over curated experiences.

[edit] The river's new course shown in the center of the image. North is to the left. Following the eruption of the Chaitén volcano, a lahar destroyed much of the town of Chaitén. The town was evacuated in May 2008 when the Chaitén volcano erupted for the first time in more than 9,000 years. The eruption, which commenced May 2, became more violent on May 5, throwing up a high plume of ash and sulfurous steam that rose to 19 miles (31 km), from which ashfall drifted across Patagonia and over the Atlantic Ocean. During 2005 small earthquakes occurred below Chaitén and the nearby Liquiñe-Ofqui Fault Zone. The town was completely flooded on May 12, 2008, after a lahar caused the banks of the Blanco River to overflow about 200 m (660 ft) on each side. Over the subsequent weeks, the river excavated a new course through Chaitén, completely destroying a significant part of it by July 2008. This process is still ongoing; it is unclear how extensive the damage will ultimately be. Some defensive work has been undertaken by the government, but they ultimately decided to abandon the town, relocating and compensating all residents. The provincial capital was provisionally moved to Futaleufú after the eruption breakout, but the capital shift was later on declared permanent. The future of the town has become a matter of political controversy in Chile.
[edit] On February 25, 2009, the government announced plans to rebuild Chaitén 10 km (6.2 mi) north of its current location in a coastal place known as Santa Bárbara or "Fandango Norte". On March 3, 2009, construction work on the new town's administrative facilities started. On April 9, 2011, president Sebastián Piñera announced a program to rebuild the town on its existing northern area, reversing plans by the previous administration to move the town to a different location farther north.
