Thunder Knob Trail
Thunder Knob
An easy trail from Colonial Creek Campground that climbs to a summit overlooking Diablo Lake and the surrounding snowy peaks. A great option for families.
The Thunder Knob Trail starts at Colonial Creek North Campground on the shore of Diablo Lake. It covers about 3 km one way and gains roughly 200 m in elevation on gentle grades, passing through stands of cedar and Douglas fir. At the end, a rocky knoll offers panoramic views of Diablo Lake, Colonial Peak, and Davis Peak. It's a rewarding trail that the whole family can finish. The round trip takes about 2 hours. Summer afternoons can be hot and exposed, so bring plenty of water.
