Nice hike, with a great view of Mammoth Hot Springs and the surrounding area. Be sure to take the loop trail down the mountian and visit Ospery Falls.
A nice easy hike. It was rather smoky the day I hiked up with my wife, due to some nearby wildfires.
I climbed Bunsen with my sister and her fiance. I think it took only about an hour or so to reach the top. The weather was great, it was breezy at the summit, but it was warm enough so that it was not unpleasant. Spectacular views of the Gallatins and Swan Lake Flat. God, I love Yellowstone.
Nice views of the Gallatins, got very close to some not-so-wild bighorn sheep
but variable weather, with fog, hail, and a cold wind in June.
