The Beartooth Highway is the section of U.S. Route 212 between Red Lodge, Montana and Cooke City, Montana.

It traces a series of steep zigzags and switchbacks, along the Montana-Wyoming border to the 10,947 ft (3,337 m) high Beartooth Pass. The approximate elevation rise is from 5,200 ft (1,600 m) to 8,000 ft (2,400 m) in 12 mi (19 km) in the most daring landscapes.

When driving east to west the highest parts of the Beartooth Highway level off into a wide plateau near the top of the pass, then descend to the junction with Wyoming Highway 296 (Chief Joseph Scenic Byway) near Cooke City, the northeast gateway to Yellowstone National Park. On the way one passes numerous lakes typical of the Absaroka-Beartooth Wilderness Area which borders the highway along much of its route. Take your time to enjoy the ride and stop to at overlooks or parking’s to admire the scenery and take picture. There are a couple of camp sites near the lakes where you can take beautiful pictures.

In Cooke City (RP10) you can plan your lunch and fill up with gas.
Official end of the Beartooth Highway and start of Yellowstone Park is at RP11.
We enter Yellowstone park and ride the beautiful scenic road, at RP12 you can briefly stop to admire the view over Yellowstone River and take a picture.

At RP13 you can park to admire the Mammoth Hot Springs and walk the 3,5 miles trail on boardwalks that also features a waterfall.

At RP18 you can stop to and walk the Fountain Paint Pot Trail where you will see various hydrothermal features that are expressions of Yellowstone’s still active volcano. Within this geologic system, each type of thermal feature is represented. They can be grouped into two general categories—those with a great deal of water (hot springs and geysers) and those with limited water (mudpots and fumaroles). Despite their structural similarities, no two features are exactly alike.

RP19 Bisquit Basin Trail is a beautiful scenic trail that loops through a number of geothermal features on a developed boardwalk.

You’ll stay overnight at the Old Faithfull Inn (RP20); one of the most popular lodging facilities at Yellowstone National Park.
