Chose this short, scenic hike for a relatively clear day when couldn't leave Seattle until noon. Drive took 2.25 hours from downtown Seattle to trailhead (driving instructions below since WTA page does not include them). Trail to Dock Butte is 1.7 miles one-way and gains 1300 feet (3900' to 5200'). Trail winds up gradually but steadily through forest and emerges onto a series of meadowed plateaus at about 4500'. Lots of possible campsites on plateau but tarns are only water source. Abundant blueberries, still edible, on the plateaus, and an array of colorful mushrooms. Full views of Mt. Baker at several points during the ascent to the butte. Trail footing very good, except for final push to top of butte, where there is a narrow and steep rock ledge, but this is only about a half dozen steps. Top of butte affords 360" views toward Mt. Baker, Mt. Shuksan, Glacier Peak area, the Sisters, and Puget Sound.
At 0.2 miles into trail, there is a short (0.5 mile one-way) spur trail to Blue Lake, a small lake sitting in a bowl, ringed with camp spots and fed by a few waterfalls. Pikas chirping across the lake.
Driving instructions: From I-5 take Highway 20 east for 23 miles, turning left (north) onto Baker Lake Road (between mileposts 82 and 83). Continue 12 miles and turn left on Forest Road 12 (the turnoff is 0.2 mile after you enter Mount Baker-Snoqualmie National Forest). Trailhead is 10.8 miles from this turn. At 3.7 miles you will pass a fork which goes to Park Butte (stay left at this intersection). At 7.0 miles turn left onto Road 1230 (right fork goes to Elbow Lake). The two intersections just described are well-marked; you follow the road for the Blue Lake trail. Road dead-ends at trailhead. There is a pit toilet at the trailhead.
