One of my favorite drives is from Seattle to Tonasket, WA, a little town about 20 miles south of Canada. My preferred route is over Stevens Pass, left at Wenatchee and up highway 97 along the Columbia river. Another route is over the lower and less scenic Snoqualmie pass (I-90) then left up Blewett Pass to Wenatchee. The better part of the drive is north from Wenatchee, the apple capital. You can see little orchards on the banks of the Columbia for much of the route. The hills and buttes are wild.
But Stevens Pass is pretty wild as well. The first town you come to as you come out of the Mountains is Leavenworth, made up decades ago to look like a Bavarian village. Not a bad job all in all. Brings in the tourist dollars.
