Any trip over the North Cascades Highway necessitates a stop at the Washington Pass Lookout.
Located at the highest point along the highway, at more than 5,400 ft elevation, Washington Pass Overlook offers stunning views of Liberty Bell and Early Winter Spires.
This section of the North Cascades Highway makes for one of the most scenic drives in Washington and is a part of the Cascade Loop Scenic Highway
I have stopped there many times on the way to or from hikes in the Pasayten Wilderness. Each time the mountain shows a different countenance. Silver Star Mountain is also clearly in view from the Washington Pass Lookout.
After Mount Shuksan I would have to guess that Liberty Bell is one of the most photographed mountains in the state, due to its stark beauty and easy access to the lookout area.
