About RMI Expeditions
RMI Expeditions is one of the oldest and largest guide services in the United States, operating within Mt. Rainier National Park, North Cascades National Park, Denali National Park and Preserve, and on all seven continents. RMI is extremely proud of the accomplishments of both our present and our past guides. Our guides have made significant impacts toward advancing the sport of mountaineering. Just a few of the names that have been a part of our guide staff are: Lou & Jim Whittaker, Dave Hahn, Peter Whittaker, Brent Okita, & Ed Viesturs. We are located in Ashford, Washington just a few miles outside of the entrance to Mt. Rainier National Park.
