Curanilahue: Mining History and Wetland

Curanilahue combines mining history, memorial sites, and nature-related attractions. In the town are the Museo Interactivo Recreación de una Mina de Carbón and the Monumento al Minero; the Humedal Urbano Río Curanilahue is located within the municipality. Further historical landmarks can be found in Colico Norte, twelve kilometers from the municipality of Curanilahue. The attractions thus range from an underground reconstruction and a memorial to miners to an urban wetland and rural heritage.

Mining History at the Museum and Monument

The Museo Interactivo Recreación de una Mina de Carbón in Curanilahue includes an underground gallery. It recreates the working areas of a coal mine to scale—that is, at full size rather than as a scaled-down model. The focus is therefore on recreating the layout of the working areas. The Monumento al Minero offers a different perspective: it is located in Curanilahue’s Eje Cívico and commemorates the 21 miners who died in the 1989 El Castaño 5 mine disaster. The two attractions can thus be distinguished as follows: the museum recreates working areas, while the monument preserves the memory of the victims of a specific disaster.

The Río Curanilahue Wetland

The Humedal Urbano Río Curanilahue is located within the municipality of Curanilahue. It is a riparian wetland with emergent marsh areas in the lower section of the Río Lebu watershed. The urban wetland was formally designated in January 2025 and covers 54.62 hectares; its designated area also includes the Parque Urbano Municipal sector. Species found there include the Chilean frog (Calyptocephalella gayi), the four-eyed frog (Pleurodema thaul), the güiña (Leopardus guigna), the Carmelita común (Percilia gillissi), the Bagrecito (Trichomycterus aerolatus), as well as Chequén (Luma chequen) and Pitra (Myrceugenia exsucca). The species list adds another perspective to the area alongside its size: it is home to amphibians, a mammal, fish, and plants.

Local Heritage: Colico Norte

Colico Norte is twelve kilometers from the municipality of Curanilahue. It is home to a mining tunnel dating from 1880, which is 60 meters long and more than four meters high. A water trough supplied steam locomotives in 1890; Edujives Herrera donated the property in 1894. The rural cemetery is among the oldest in the municipality of Curanilahue, and some graves date from 1899. The local chapel also contains a very old bell. The dates therefore span the mining tunnel, the railway water trough, and the land donation, through to the early graves.

Route and Past Festival

A day-trip route described in 2012 led to the Trongol Alto sector at the end of the valley, at kilometer 25 from Curanilahue; it could be traveled on foot or on horseback. In 2026, the two-day eighth edition of the Festival del Río – Nahuelbuta Libre took place in the Puente Mundo Nuevo sector on the Río Carampangue. It was organized by Rafting Nahuelbuta with support from the Municipality of Curanilahue.
