Boise - Idaho city - Lowman - Grimes pass - Banks.
Either direction is an absolute hoot to ride, unique terrain,
A little used road, old 95 is quite tight as you gain elevation, the asphalt is quite good considering it is somewhat abandoned. The charm is the banked corners, like riding up a big luge course.
Back woods rural road in prime Okanagan.
Hedley Nickel plate road, great dirt road unto Apex mountain resort.
Ross is a short but fun road north from 8th
Beautiful country ride through meandering roads.
From Nooksack continue on south pass to Silver lake, Maple fall the onto Mount Baker Park. Once in the park take the narrow, mostly paved road to Heliotrop ridge.
From Mammoth lakes through Yosemite the road gets more curvy and thrilling. Highway 108 is my all time favorite Californian road, closed in winter it is a mountain roller coaster for motorcycles.
Hells canyon is a very narrow extremely twisty road along the snake river. A boring country section in the middle then the final decent into Clarkston is spectacular.
Beautiful forested road through national parks
Very entertaining. Watch for speed change from Mt. to ID
Highway 20 closed in winter, beautiful Alps like mountain section descending into dry Okanagan desert.
Scenic desert canyon twisties.
