The Washington Pass Overlook Trail, designated a National Recreation Trail in 1978, runs a short 0.2 miles (0.32 km) from the pass to an overlook with views of Liberty Bell Mountain and the highway 700 feet (210 m) below.

[1] Washington and Rainy Passes are located in the marine west coast climate zone of western North America.

[2] Most weather fronts originate in the Pacific Ocean, and travel northeast toward the Cascade Mountains.

As a result, the west side of the North Cascades experiences high precipitation, especially during the winter months in the form of snowfall.

[3] Because of maritime influence, snow tends to be wet and heavy, resulting in high avalanche danger.
