Enjoyed the beautiful views all the way to the top.

As relatively new hikers from sea level, this hike winded us but was very rewarding to complete. Great views and not very technical. Say hello to the chipmunks at the top.

The hike itself wasn't too bad, though the switchbacks were a little rough. The views on top were breathtaking and worth the climb. In the distance you can see Mammoth and Gardiner, Swan Lake, and other small lakes. I went in the beginning of August so it was a little hazy from fires. The wild flowers were in full bloom and many wild raspberry bushes lined the trail. My group saw a male and female sage grouse on the way down.
The only downside is the noise of cars down below so it isn't as quiet as I would have liked.

On recommendation of a friend we went on this trail and it was one of my favorite. It was a lovely climb that went through a small forest and field on the way up, a great chance to see lots of little creatures. After getting through the forest and field a steady climb up leads to spectacular views in more than one spot. I could have stayed there all day taking in the 360 views and breathing the fresh air. A must do if you are in Yellowstone.

A beautiful hike. It was difficult, especially at the top where it was very rocky, but well worth the work-out. A photo journal of our hike can be found here: https://www.youtube.com/watch?v=8o5ZycUp4L0

This trial was moderate (easier than hard) and moderately trafficked (rather than lightly trafficked). The trail passed through grassland, forest and scree. About halfway up is a large rock, shaded by a lone tree, that makes a perfect lunch stop. At the summit, there is a unmanned ranger post, weather station, comms tower.

Excellent trail due to views, variety of vegetation and steadiness of incline.

Half of this trail is covered in beautiful flowers during late June and early July. The upper half is strenuous and very rocky with lots of scree. It is a pretty trail, but it is a true summit. You switch back all the way up and there are no additional fun surprises along the way. For us, the first half with the flowers were pretty and warranted the 4 star rating, otherwise, the second half would probably be 3 stars. We enjoyed the workout but we also enjoyed other views in Yellowstone more.

Phenomenal hike. The incline was somewhat steep, but the views are well worth it. Also make sure to walk past the tower to get a breathtaking view. Remember to sign your name in the log book on the cabin!

Great short hike! Gets pretty steep but there were several groups of families with children the day we went. There IS still snow in a couple spots.

Short and moderate trail whit a good view from the top. In the last meters there are a lot of stone and walk is not so easy but not so hard.

Steep trail up the mountain. We hiked a few days ago at the beginning of June, and there was some snow on certain parts of the path but nothing you can't get past. Near the peak, there's a slope that's more like a rock scramble. The view is beautiful and well worth the effort though!

We had lunch at the peak and continued our way to Osprey Falls. It was a long descent down to the falls. As several others have commented, some of the switchbacks are steep, be careful not to slip. The hike back up was quicker and easier. Amazing experience standing at the bottom of the waterfall! We took the flat trail back to the parking lot.

Several others were hiking Bunsen Peak, much less people hiking to Osprey Falls. Saw several little critters along the way but no bears.

Difficult trail, especially at the top due to loose rock. The sights are amazing for the entire trip. And don't forget to sign the notebook on the station at the top!!

Good hike with nice views of the mountains and lakes at the top. Didn't spot any wildlife. Hiked at the end of May and there were still some snow patches we had scamper across - if you have walking poles I'd recommend you bring them as the snow was pretty icy and slippery. We got lost a bit as the trail wasn't evident. For the last 0.4 miles it's all rocks and the dirt trail disappeared. We followed lighter red rocks up to the top, though we weren't sure if it was a proper trail. There's a small hut at the top so you'll know when you reach it. Took us about 3 hours round trip - the rocks took a while to climb over.

This was an incredible, yet difficult hike. I hiked this yesterday (early May) with the goal of continuing over to Osprey Falls, as was recommended by locals. The hike has breathtaking views, with moderate inclines for the first mile or so. The second mile up was a lot steeper, and we had to climb through some snow and get off the trail to make it all the way to the top. It was doable, but the trail gets progressively steeper and the terrain gets more rugged, filled with little rocks. I would absolutely do this hike again, it has so much to offer. We did stumble across a large black bear as well who looked at us then continued on his way. I don't recommend going through the otherside to reach Osprey Falls until the snow has melted and the trail is more used. It currently was covered in snow, fallen trees and little unstable rocks. All in all a truly incredible hike with breathtaking views!

This hike was incredible. Due to the snow, we couldn't make it to the top but we made it .4 mile from the top & the view was fantastic. Bring bear spray, as we saw fresh tracks. It was tough in spots but reasonable, the incline is quick but not impossible. I would recommend to anyone looking for a short hike was a challenging hike.

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!!

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.
