Thunder Knob Trail

Thunder Knob Trail Professional Review and Guide

"From popular Colonial Creek Campground in the Ross Lake National Recreation Area, this short and easy hike takes off for a promontory high above manmade Diablo Lake. A series of overlooks along the way allows you to admire the surrounding majestic North Cascades summits hovering above, or to marvel at the blue-green waters of the glacier-fed lake twinkling below.

Thunder Knob makes a perfect family-friendly hike if you’re camping below, or a great leg stretcher if you’re traveling through on the North Cascades Highway. The trail is all accessible too, meaning outdoor lovers confined to wheelchairs can also enjoy this hike. And due to its low elevation, it rarely snows on the knob, allowing for winter rambling in the heart of the North Cascades National Park Complex."
