According to Outdoor Project, “Diablo’s turquoise waters are the product of glacier-ground rock silt, which is carried down from these mountains by streams. This “rock flour” reacts with light to give the lake its bluish-green hue.”
There isn’t a bad picture at this viewpoint. It is a great place to stop for a quick lunch. The overlook parking is big enough for even a busy afternoon. We stopped for lunch, a quick bathroom break and then continued on our ride down highway 20.
