Tallest Mountains in the Pacific Northwest
The Pacific Northwest (PNW) is defined by the massive volcanic “monsters” of the Cascade Range and the rugged, high-desert peaks of Idaho’s Rockies. This list combines the highest summits from Washington, Oregon, and Idaho.
While Washington dominates the top of the list with its massive volcanoes, Idaho’s “twelve-ers” (peaks over 12,000 feet) fill out the ranking, showcasing the geographic diversity of the region.
