Beartooth Highway, Cody and Yellowstone Loop
From Bozeman, cross the Beartooth Highway to Cody, enter Yellowstone by the East Entrance, and exit by the West Entrance via Big Sky.
This puts Yellowstone into a bigger loop: first cross the high-mountain road to the Western town of Cody for its museums and rodeo, then enter the park by the East Entrance, see Lamar Valley on the northern route and the geysers on the western route, and finally return to Bozeman via Big Sky. Grand Teton is left out in exchange for Western culture and a stretch of high-altitude road, a good fit for repeat Yellowstone visitors or road-trip lovers.
The Beartooth Highway is open roughly from late May to mid-October. Snow is still possible in early June, so follow local road conditions.
