4.0 Miles Strenuous
The Bunsen Peak Trail in Yellowstone National Park is an amazing and strenuous 4 mile out-and-back hike to the summit of Bunsen Peak.
The mountain is located in the northwest section of Yellowstone, but the views from the top are just as stunning as anywhere else in the park. At the summit, you get a 360 degree view of north Yellowstone and central/south Yellowstone.
This is by far one of the best hiking trails in Yellowstone National Park.
