The Kendall Katwalk is a nice moderate hike within easy reach of Seattle, only about an hour to the trail head. This is one of my favorite hikes close to Seattle. Heading north from near Snoqualmie Pass, it follows the Pacific Crest Trail climbing about 2700 feet over 5 or 6 miles.
The trail was blasted out of the sheer rock face using dynamite. Don't attempt to cross the Katwalk if it still has snow on it - it's a long ways down if you slip.
The hike is a moderate hike on a well-marked and well-maintained trail. The trail-head is easy to find near Snoqualmie Pass off exit 52. At the bottom of the exit ramp, turn left. In a few hundred feet, take the first right onto the road to the Pacific Crest Trail parking lots (Northwest Forest Pass required).
The beginning of the hike is through the forest on an easy trail. Nowhere does the trail get very steep.
The trail passes through meadows filled with wildflowers, and along streams.
Watch for great views of surrounding mountains. It is obvious how Red Mountain got its name. Guye peak is the far left peak of the mountain complex in mid picture.
The total round trip to the Katwalk is about 11 miles, although I suggest adding a couple miles to that and go to the lakes beyond for lunch before returning. Gravel Lake and Ridge Lake are on opposite sides of the trail. Ridge Lake looked more inviting to me.
You will get another view of the Kendall Katwalk when you turn around to head back, seeing it from the north.
To get to the trail head, (from Seattle) take the West Summit exit on Snoqualmie Pass. Go left (north) under the freeway toward Alpental. A few hundred yards up the road you will see a road to the right that goes to the trail head parking lot.
