This is another amazing destination along the Pacific Crest Trail near Snoqualmie Pass east of Seattle. It's a bit long for a day hike so you could camp at Ridge Lake about .5 mi further past the Katwalk itself. The Katwalk is a narrow pathway that was blasted out of a steeply sloped rock face. It doesn't feel nearly as precarious as some photos make it appear, but you still might find yourself hugging the rock side as you pass through. When I first saw photos of the area I knew I had to get there. You will too.
You'll have a long trek through old-growth forest, open talus fields and a wildflower field known as Kendall Gardens before entering the Alpine Lakes Wilderness approaching Kendall Peak, where the Katwalk begins. We stopped here for lunch before checking out Ridge Lake and returning.
