Washington is one of the most diverse regions of the United States. The terrain includes glaciated peaks, active volcanoes, desert plains, alpine rainforest, Pacific coastline, and the Columbia Gorge. From a mountaineer’s perspective, the most exciting terrain resides in the north and west portions of the state, which include the rugged, glaciated peaks and the Cascade volcanoes.

The Cascade volcanoes are the most famous high-altitude terrain in the state. These volcanoes include Mount Rainier, Mount Baker, Mount Adams, and Mount St. Helens.

The gem of the Cascade volcanoes is Mount Rainier. At 14,411 feet, Mount Rainier rises from the sea level terrain of Seattle, and dominates the skyline from a great distance. Seventeen mountaineering routes cover the flanks of Mount Rainier, entertaining amateur and expert climbers alike. Mount Rainier is internationally recognized for its rugged glaciers, superb scenery, demanding terrain, and volatile climate. The mountain serves as a training ground for international expeditions in the Andes and the Himalayas.
