RMI Expeditions

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 45 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.

We have a long and celebrated history as a leader in the mountains. The programs we offer have been tried and tested by more than three hundred guides and over 80,000 climbers over the course of the past 45 years! Whether measured in years of operation, numbers of guides who learned their trade under our banner, or the great number of folks with whom we have climbed, we have more experience guiding glaciated terrain and expedition-style adventures than any other American mountain guiding service. Our experience, starting with the planning that goes into each trip through to the decision making that takes place in the mountains, gives us the expertise to provide the best possible mountain adventures!

RMI Expeditions' goals are:

To make every effort to attain our goals while maintaining a responsible margin of safety.

To share our mountain experiences and teach others to climb safely and knowledgeably.

To climb responsibly and to protect and preserve all natural and cultural resources in the places we travel.

To make every adventure a meaningful and enjoyable experience.
