The LANL Trails Working Group inventories, maps, and prepares historical reports on the many trails used at LANL. Some of these trails are ancient pueblo footpaths that continue to be used for recreational hiking today. Some serve as quiet and non-motorized alternatives between the Townsite and LANL or between technical areas.

The Trails Working Group, established in December 2003, includes representatives from local citizen hiking groups, Los Alamos County, Forest Service, Park Service, Los Alamos National Laboratory and the NNSA Los Alamos Site Office. Trail Working Group meeting notes are available upon request. Please contact trails@lanl.gov for more information.

The Trails Working Group carries out the Trails Management Program, which was a requirement stipulated in an NNSA environmental assessment and Finding of No Significant Impact (FONSI) (pdf) completed in 2003. The program addresses various issues related to hiking on Laboratory property. Through this program, an active needs assessment was completed on how to manage foot traffic, control looting and vandalism, protect the scientific value of sites near trails, and provide the proper respect for sites that are sacred to local pueblos.
