Diablo Lake Overlook

Diablo Lake Overlook sits at 1,672 feet along the byway between the Keystone Ferry zone on Whidbey Island and SR 153 near Twisp, facing 300 degrees toward glacial-fed Diablo Lake and Diablo Dam. The terrain drops 463 feet within 600 meters of the overlook, giving an open view down toward the lake and the rugged mountains around it. Visible peaks include Davis Peak to the west-northwest at 5.0 miles (7,003 ft), Mount Ross to the west at 6.7 miles (6,030 ft), Inspiration Peak to the west-northwest at 9.6 miles (7,833 ft), and Mount Degenhardt to the west-northwest at 10.0 miles (8,020 ft). In summer, the lake takes on a turquoise color caused by glacial flour, fine rock particles carried into the water by glacial streams, with the color most pronounced on sunny days in July, August, and September. The overlook faces toward the sunset, roughly 30 degrees off square, with sunset times ranging from about 16:11 in December to 21:12 in June. Concrete lies 31.9 miles west-southwest, and Darrington is 39.2 miles southwest. Visitors are asked not to feed wildlife or leave food and waste unattended.
