I have done these on a motorcycle and they are both beautiful.Montana has a bunch. Going to the Sun in GNP is decent and Beartooth Pass between Red Lodge and Cooke City has been called the most scenic drive on the planet by at least a few people.......
Dream it… do it . Done it with a motorcycle and our Jeep.How many people dream of driving the Pacific Coast Highway?
Forgot, the best drive is up to Copper Harbor and then down to Eagle Harbor on Hwy 26In Michigan, M-22 up by The northwest corner of the lower peninsula is beautiful. Then the tunnel of Trees is another pretty road. Alone the shores of any of the Great Lakes have nice views.
I have been fortunate to have done both on motorcycles and bicycles many times. Nothing like bicycling going to the sun under a full moon.I have done these on a motorcycle and they are both beautiful.
And continuing thru WA all the way to Olympia.US 101 all the way from Brookings, OR to Astoria, OR
