Green Lake Falls is a large, year-round waterfall in Washington’s North Cascades National Park, just below remote Green Lake. Reaching it is notably difficult because of the rugged terrain and glacier-fed streams around the lake. The main falls descend 979 feet across several tiers rather than in one continuous drop, including a 300-foot slide and a 500-foot plunge, and average about 150 feet wide. An additional 175-foot drop upstream can bring the total descent to nearly 1,260 feet if counted together. Fed by streams from Green Lake Glacier, the falls stand out as one of the North Cascades’ most dramatic yet least accessible cascades.
