Went with my mom in first week of September of 2014. Awesome views the whole way up, nice panorama at the top. Went early, about 7 AM, and didn't see anyone else until we were about halfway down.
Not too difficult at all. If you follow the trail, a few spots to rest along the way will get you there with ease. Make it more difficult by traversing up past the narrow outlined paths and through the trees and loose rocks. That will give you a good workout. I was surprised to see the communications cabin at the top, but the view was great.
Gorgeous views. Steep going up, but short. There was still a good bit of snow and ice at the top when we went, which was tricky to navigate around because the top is mostly rock. There are some power lines at the top that aren't very pretty, but overall fun hike with great scenery. Also fun to do with kids.
On the day we hiked this trail, weather at trailhead was cloudy. Visibility was pretty limited as we climbed through the fog (clouds) toward the top. Trail is steep but well-switchbacked. Shortly after we passed Cathedral Rock, we found ourselves ABOVE the clouds with spectacular views of nearby mountaintops in all directions! The sight of all these mountain peaks poking out above the clouds was jaw-dropping – it was like we were on a sea of clouds! This experience was probably the highlight of our entire Yellowstone trip. After you enjoy a well-deserved rest break on top, return on main trail or continue down back side of peak (also pretty steep) to service road and back to trailhead, with optional side trip to Osprey Falls. As always, carry bear spray and make plenty of noise.
We started this hike early in the morning. We did not go directly out and back as in the description for the hike. From the top of Bunsen Peak we continued off the backside and continued down to Osprey Falls returning via the road to Osprey Falls. It was a strenuous hike, especially the hike in and out of the canyon to see Osprey Falls.
The hike up to Bunsen Peak has some spectacular views of the surrounding area. You can see the Mammoth Hot Springs area and all of the people way down there. It is amazing that with just a little effort and some hiking all of the crowds just vanish. We encountered one lone hiker descending from Bunsen Peak, a group of 4 that were on the top and absolutely nobody on the backside until reaching Osprey Falls.
I did this hike with my wife, 10-year old son and 14-year old niece. It was difficult and I would not suggest having kids do this unless they are used to some serious hiking. My son was riding a scooter around the campground not too long after the hike, so he still had energy...oh to be young!!
Great hike, strenuous but worth it! The views are majestic!
Beautiful trail that goes through burnt forest as well as open vistas and even quite a bit of snow in early June. My only complaint is that the power lines on top of the peak was not appealing. There was almost no one on this trail when we hiked it and I kept singing to scare off the bears....
We enjoyed the challenge of the this trail. It is a difficult ascent to a spectacular view of the valley below. Take plenty of water and snacks but it is worth the effort.
Hiked this on our trip in Yellowstone when Mt Washburn was snow covered. Great alternative. Nice hike up, challenging. There was some snow on the trail, but nothing insurmountable. Did pass some kids coming up around age 10. At the top, quite a view of the park. 360 degrees of beautiful views. NIce view of Mammoth Hot SPrings. A good deal of elevation change in only 2.2 miles.
