Thunder Knob Trail

Thunder Knob Trail Professional Review and Guide

"This short, well-constructed new trail goes to breathtaking viewpoints. The grade is so gentle that, if it were paved, it could be a barrier-free trail. Children can look down on Thunder Arm with its unearthly turquoise water and across to enormous glaciated peaks and spires, from three sitting areas at the summit of Thunder Knob. They will dream of paddling a canoe on the still waters or climbing these surrounding mountains someday.

The campground is divided by the highway. Begin by walking into the north side of Colonial Creek Campground. The road is frequently gated. Following the trail signs, stay right where the road divides, and walk pavement past campsites one through ten. Beyond the tenth campsite the road was ripped up and covered by gravel and boulders when Colonial Creek flooded in 2003. The trail crosses two of the deepest flood channels on large logs before entering the forest and crossing the original channel on a well-constructed bridge."

This is nice hike through evergreen forest to a wonderful view of Diablo Lake far below. The trail rises 650 feet over two miles. Since the climb is steady over the entire two miles it is really not noticeable. Wonderful views of the North Cascade range from different viewpoints. Highly recommended
