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.
