Yosemite Mountaineering School classes are designed to give climbers of all levels new and extended skills. Climbing classes average seven hours in length, unless otherwise noted, so prepare for a full day of fun. Guides meet their students at the Mountaineering School in Curry Village or in Tuolumne Meadows. Their classes build upon each other and are designed to be taken sequentially, so that you can pick the single class you need, design the perfect multi-day seminar, or come up every couple of weeks and complete the entire curriculum.
