[7] The unique ecosystem of the southern Chilean Coast Range and Valdivian temperate rain forest makes this a priority site for biodiversity conservation.

[8] From about 1750 to 1943, when the land between Maullín River and Valdivia was colonized by Spain and then Chile, numerous fires of Fitzroya woods occurred in Cordillera Pelada.

Earlier, from 1397 to 1750 the Fitzroya woods of Cordillera Pelada also suffered from fires that originated from lightning strikes and indigenous inhabitants.

The park is part of the Valdivian temperate rain forest, and located in the Coastal Range of the communes of Corral and La Unión.

There is an alternative route for standard vehicles via the road joining La Unión and Santa Elisa in the Cumleufu area.

In the north area (Catrilelfu, Las Romazas) there is a CONAF office with park rangers, tourist information and safety advice.
