Washington Pass (el. 5477 ft./1669 m.) is a mountain pass on State Route 20 (North Cascades Highway) in the North Cascades Washington. The pass is in both Chelan County and Okanogan County. Rainy Pass is about 4 miles to the west of Washington Pass. The passes are typically closed between November and April due to heavy snowfall.
The Washington Pass Overlook Trail, designated a National Recreation Trail in 1978, runs a short 0.2 miles from the pass to an overlook with views of Liberty Bell Mountain and the highway 700 feet below.
