Mt. Rainier

Mount Rainier is the undisputed monarch of the Cascade Range. Standing at a formidable 14,411 feet, it presents a true high-altitude, heavily glaciated mountaineering environment right here in the lower 48.

Because Rainier demands exceptional physical fitness and polished technical movement, Timberline Mountain Guides utilizes our local volcanic terrain to offer specialized training preparation, route-specific clinics, and custom-guided itineraries designed to give you the exact technical competence and endurance needed to safely step onto Rainier’s massive glaciers and achieve its storied summit.
