Climbing the Beartooth Highway northbound from near Crazy Creek Falls puts you immediately into one of America's most spectacular high-alpine environments, ascending across the vast 'Top of the World' Beartooth Plateau. Starting already at significant elevation around 8,000ft, you'll tackle the upper section of the climb over perhaps 10-12 miles, gaining around 3,000ft to reach the breathtaking 10,947ft summit. Expect a sustained climb across stunning tundra landscapes dotted with alpine lakes averaging around 5-6% for this portion, it will feel hard due to the extreme altitude and frequent strong winds. You'll catch glimpses of the Beartooth summit as you traverse the highway enroute.
