The Hundred Peaks Section (HPS) is a mountaineering society within the Angeles Chapter of the Sierra Club that serves to provide mountaineering activities for Sierra Club members in the southern Sierra Nevada, the Transverse Ranges, and the Peninsular Ranges, and to honor mountaineers who have summited peaks in those mountain ranges.
The section hosts summit hikes and scrambles in the Los Angeles and Inland Empire area three to four times per week. These hikes are open to the public.
