Mountaineering is the sport of climbing mountains. Unlike rock climbing, mountaineering is typically done by a group of individuals, often roped together as they do semi-technical ascents of large mountains either on just rock or snow and ice. The ATS Team enjoys exclusive access to the tallest mountain in Los Angeles County where we teach our courses as weather conditions permit. This is typically from November to March of each year.
