The North Cascades in Washington highlight the end of the Pacific Crest Trail, featuring a rugged route through deep canyons and mountain passes. The trail ends at the US-Canada border seven miles south of Highway 3 in British Columbia. Along the way, hikers encounter scenic spots like Mount Adams, Fire Creek Pass with views of the North Cascades, alpine meadows in Glacier Peak Wilderness, Packwood Glacier, bears, wildflowers, and glacial lakes before finishing their journey at the border.
