RMI HAS BEEN SETTING THE STANDARD IN MOUNTAIN GUIDING EXCELLENCE SINCE 1969. Getting safely up and down mountains is just the beginning of the story at Rainier Mountaineering, Inc. (RMI). Founded by the legendary Lou Whittaker and staffed by the most experienced and talented guides in America, RMI has built a four-decade long legacy of safe, successful, and enjoyable mountaineering adventures. Experience matters in the mountains, and that is exactly what we have gained over the last 40 years. There is no substitute for the years of expedition guiding around the world, over 300 Mt. McKinley Expeditions, over 80,000 climbers on Mount Rainier and some of America's first ventures into the far reaches of the Himalaya.
