Thunder Knob Trail

Thunder Knob Trail leads from Washington State Route 20 up to ridges overlooking Diablo Lake and Diablo Dam.  Starting at the Colonial Creek Campground, the trail first crosses the creek over a bridge that is removed in the winter to prevent damage from the rampaging water in the creek.

Continuing along the creek

We soon start up toward the top of Thunder Knob.

Heading up

As we reach the half-way point, we are rewarded with views of Diablo Lake, after which the trail becomes much steeper to bring us to the top.

Rest stop along the way

Soon we reach the top and absorb the breathtaking views of the lake and the dam.

At the top

We head down to the trailhead to resume our journey west out of the national park.  This trail has been a great opportunity to take a break from driving through the mountains and see more incredible views.
