A steep scramble up Red Mountain. When dry, this roughly 40 degree incline is mostly a walk-up with hands needed here and there. While still a walk-up, you can test your vertigo on the last 1000 feet while climbing the red west slope of Red Peak.
From the top the various peaks in the Snoqualmie Pass area are visible. The first five miles are on well-maintained trail passing through old growth with areas of blueberries and salmonberries. The final ascent is on fairly solid rock with scree in areas, bits of heather and blueberries, and a scattering of alpine trees gripping on here and there. Some of the rock is smooth so, if wet, might be too slippery to climb without aid.
