The Beartooth Mountains are a massive mountain range that extend out of the northeastern Absaroka Mountains. They feature one of the largest expanses of alpine tundra in the entire country. Crossing over this tundra is the All-American Scenic Road, the Beartooth Highway. Visitors to Yellowstone drive this highway to access the northeast entrance of the park. This is also the least accessed entrance, making it an excellent way to escape the crowds. The mountains themselves are home to endless hikes and fishing, including the Beartooth Loop, a National Scenic Trail.
