One of the Top 10 North America Scenic Drives is in the Cascade Mountains of Washington State. I-20 snakes it's way through the Cascade National Park to an elevation where even in the July heatwave, there are snow patches by the road. If travelling by motor-home or motorcycle, take note that the road surface is excellent.
Just when you think the scenery of rugged peaks, wildflowers and green alpine slopes can't be topped, the road brings you to Diablo Lake. Fed by glaciers the water takes on a blue color that just doesn't seem real. Memorable and truly one of the Top 10 North America Scenic Drives.
