The HRA is a voluntary non-profit organization which strives to reduce casualties in the Himalayas of Nepal. It was founded in 1973 and now operates Aid posts along the two most popular trekking routes. One is located at Pheriche (4,250m) on the way to Everest and the other is at Manang (3,550 m), just before Thorung-la pass on the Annapurna circuit. Both Aid-posts are staffed by volunteer doctors during the two main trekking seasons, spring and autumn.

HRA also runs Everest ER medical clinic at the Everest Base Camp (5,350 m) since spring season 2003. HRA-Everest ER provides medical facilities to the climbers, support staff and visitors at EBC.
