This is a nice easy hike with a mellow trail grade featuring some nice stands of forest as well as a couple of fine views once the top is reached. The Trailhead is clearly marked across from the Colonial Creek Campsite at mile marker 130 along SR20 in Northern Washington.
Roundtrip 3.8 miles
Elevation Gain 635 ft
Highest Point 1875 ft
Further trail description and information:
Ample parking at the trailhead. A walk through the rustic campsites with many fine tenting only sites near the shores of Diablo Lake
Soon you come to the well-marked trailhead.
Crossing a nice forest creek
Walking gently upward through some lovely stands of forest
Look for some pretty flowers along the way, like this Calypso Orchid
First viewpoint, looking to the south
A second rest stop, along the shores of Thunder Lake (nothing like our Thunder Lake in Manning Park)
More views begin to open up as the forest changes to more thinly populated ponderosa pine
Thee are two viewpoints atop thunder knob. The first looks back on SR20 and Diablo Lake towards the dam.
The second viewpoint, about another 100 metres further, looks more eastward towards Mt. Davis
This is a great family hike as the grade is mellow, the trail is wide, and the views and forest diversity keeps things interesting. As always for me, no trail is complete without a fine beer [8D]
