definitely advise some spike shoes for peace of mind-higher you go the pathway gets a bit icy in some precarious locations but an enjoyable hike with incredible views (very windy at top, layer up)

Great Hike, Windy at the top, steep at times.

Great way to elevate your heart rate! Upper Bear Peak is as normal, eroded, loose, steep, lots of opportunities to crash on way down. All ice on this trail is now melted until the next snow storm, no need for Kahtoola Microspikes, or Yaktrax.

You need crampons/yaktrax to complete the full hike at this point. Far to icy for simple hiking shoes, don't be fooled by warm temps either, shady trails can keep ice for a long period of time, and it gets packed in by hikers over time.

This is definitely a challenging hike, but the view from the peak is amazing. FYI, if you’re afraid of heights, the end of this hike can be a little sketchy. But if you’re ok with jagged peaks, then sitting at the top on a sunny Fall day is incredible.

Definitely one of the hardest climbs I've ever made. Equally rewarding though!

very challenging hike. Last 1/2 mile is very steep but awesome workout. Beautiful views at top! You can see very far west, possibly even Winter Park ski runs (I think).

The hike up Fern Canyon is no joke but the views from the top are incredible. Make sure to hop over to South Boulder too! Definitely worth the easy additional mile.

killer trail, and I mean that in the best way possible. good little scramble near the top, which had incredible views. only downside was the plethora of bugs at the summit.

Awesome hike! Strenuous, steep incline until the Fern Canyon overlook. From Fern Canyon up to the top of Bear Peak is a very strenuous climb, stair-stepping on rocks to the top. The view is completely worth it! Feels like you can see the whole state from up there. Come prepared with a hat, lots of water, and snacks. Best on cool, cloudy day.

Great but strenuous hike up to one of the highest peaks right above the city of Boulder. Pretty tough incline that gets steeper as you get close to the top. Views from the summit are amazing!! Very buggy at the very top localized to one rock at the summit for whatever reason. Bring lots of water!

Great hike. Beautiful views. I'm not the most in shape person. Definitely felt this one the next day.

Fun and challenging trail with some beautiful views and fun scrambles on the way up. Was killed by the swarm of black flies at the summit though. Not sure if it's a seasonal thing, but it was so bad I could only stay at the summit for a minute before having to run down to get away from them.

Great trail, great views.

Got a little elevation sickness after flying in the night before from sea level. Nothing like a little coffee and dip to power through.

Do NOT attempt without ice cleats. (Yes, this was written in May)

Went early this morning with Yak-Trax in my bag and started using them after Fern Canyon. Pretty much the whole way to the Nebel Horn was good. After that I made it about 1/3 of the way until it got too steep for how icy it was. Very glad I turned around when I did though because getting down showed how slippery it really was. I actually fell 4-5 times and slipped more than I can count. Very dangerous.
Maybe it would have been fine in the afternoon, but remember that section is North facing, so there is just enough sun to melt everything from the trees and refreeze into an ice river.

Every time I've been to the horn it's been ridiculously windy, even when calm the whole hike, so be prepared for that.
