Areas of use and conflict between salmon farming and tourism were identified in the pre-Andean area of the Araucanía Region, Chile. To do this, variables of suitability and of technical and legal restrictions were determined and incorporated using a Geographical Information System. Subsequently, the perception of actors in the communities in response to the two types of activity were evaluated. The results allowed three sectors of spatial conflict to be identified, all in the district of Pucón. A register was made of 245,113 ha which are potentially suitable for the installation of salmonid species cultivation centres. However the perception study revealed that a large sector of the population is against the installation of new cultivation centres. Meanwhile tourism is perceived as an activity which generates more local employment; however the environmental effects of the two types of activity are not clear to the population.  Se identificaron las áreas de uso y conflicto entre la salmonicultura y el turismo en el área preandina de la Región de La Araucanía en Chile. Para ello se determinaron variables de aptitud y de restricciones técnicas y legales que se integraron a través de un Sistema de Información Geográfica. Posteriormente, se evaluó la percepción de actores comunales frente a los dos tipos de actividades. Los resultados permitieron identificar tres sectores de conflicto espacial, todos en la comuna de Pucón. Se cuantificaron 245.113 ha potenciales de aptitud para la instalación de centros de cultivos de salmonídeos. Sin embargo, el estudio de percepción mostró que un amplio sector es renuente a la instalación de nuevos centros de cultivo. Por su parte, el turismo se percibe como una actividad que genera mayor empleabilidad en el sector, pero no es claro para la población los efectos ambientales de ambas actividades.
