Due to its accessibility by vehicle and its surroundings, the refuge is a magnificent point for the development of introductory activities to the different mountain sports. The Lizara refuge has been certified with ISO 14001 since October 2004, thus supporting an environmental management model. The Valles Occidentales Natural Park, where the refuge is located, was declared in 2006, in an environment that combines medium and high mountains. In winter, a cross-country track is set up on the Llano de Lizara, which is managed from the refuge itself. Certification according to ISO 14001 was a pioneering experience in Spain and the Pyrenees in terms of mountain refuges, where a model of environmental management is supported with the installation of renewable energy sources, the regular practice of selective waste collection and environmental awareness campaigns.
