This highway takes you from North of Seattle over the Cascade mountain range to Eastern Washington far into Idaho and Montana if you want (I do recommend crossing states on small 2 lane highways whenever possible). The highlight of this road for me is the North Cascades National Park. When driving through the mountains make sure you stop and look at the turquoise waters of Diablo Lake. I love the contrast of going through the lush green dripping forests on the west side of the mountains to the dryer rain shadow ponderosa pine forests to the east. The town of Winthrop epitomizes this climate change with its Wild West theme. #views #photography #climbing #mountains
