Boulder, Colorado Map

Did this in the evening 1/17. Trail is completely clear of snow— a little muddy in certain parts. This route is very rocky and has lots of big steps. I have bad knees so going downhill was rough. I’ve done this hike from the east ridge before and prefer that route (via goat trail). Less crowded on that route and not so rocky.

Pretty but super icy and muddy! 01/17/2019.

This is a great, easy hike. Very beautiful!

It was snowing when I did this trail last week, but still completely doable. I didn't want to snowshoe or struggle to get to a trail head, but still wanted nice views. This hike checked all the boxes. I wore spikes, but you could easily do the trail without them. Even in the snow, I passed several other hikers. I imagine it's a very busy trail when the weather is better.

trail was snowy so we walked the road up. saw a herd of deer! pretty hike and really easy.

There was one section of the trail that I completely missed somehow according to the map on here but otherwise a great short hike. Icy and muddy right now though so proper footwear is definitely reccomended.

Very icy near the top. A bit of a scramble too, most dogs wont make it the last .4

Great hike. Did a winter sunrise hike to Bear Peak on 1/15/19. Started the hike at 4:30am and made the sunrise just in time. Definitely not the smartest decision, but the sunrise was beautiful. Trail is packed down and icy. At the top of the peak, for a section of ~100ft or so, it is going to be tough with snowpack in some places. I don't have microspikes, but they would have been extremely useful and cut down the hike time substantially.

This hike was so enjoyable, with hardly any huffing and puffing. Nothing but spectacular views from top to bottom. To top things, we only saw one other hiker. You can see everything from the top including the Indian peaks wilderness, and I am pretty sure even longs peak to the north. You could still see boulder also. This is a great beginner’s hike. It was breathtaking with all the snow called vistas!

beautiful trail and perfect weather on 1/14. 6-8 inches of snow on each side of the trail, moderately packed snow on the trail itself. used micro spikes pretty much all the way.

easy fun hike with good views! I went during the sunset. took a few breaks but otherwise quick hike.

Today we did the Canyon Loop. It had quite a bit of snow but it was well packed so no need for snowshoes. There were some muddy spots. This was an easier hike.

Rangers recommmended that I did not go up the royal arch without micro spikes! Flat irons loop was icy and snowy as it is!

Icy and snowy on trails! Need micro spikes or at the very least hiking shoes!

Pretty. Nice incline. Brought my 70lbs greyhound and the up was fine but going down was too steep with big rocks to climb over, so we had to go down Sanitas and take neighborhood roads back to the car. I won't take it again.

I hit this trail around 1:30 on Saturday afternoon, fresh snow from the day before made for a beautiful and peaceful hike! I had my snowshoes with but did not need them. took around 1 1/2hrs at a casual pace, with a few minor detours.

Hiked 1/13/2019. Trail was pretty muddy

Hiked 1/12/2019. Lots of snow, microspikes are helpful. Trail is easy to find. Started at 8:30am, only passed a few people coming up, but trail was busy on our descent.

Just came back from Switzerland Trail, it was really nice and easy with great views until we passed Gold Hill Rd going North. Andrea below wrote a warning but I totally didn’t see it. I would not recommend going that last stretch of the trail, at least not this time of the year. It gets extremely narrow and slippery. The back end of our 4Runner (on brand new Wildpeaks) almost slipped off the trail. I was able to save it but we had a really hard time, and turning around was almost impossible. We were finally able to turn around without damage but it took over 2 hours. On the way back we saved a Dodge Ram that was also having a difficult time.

Great views. Did trail clockwise so went up the stairs which felt safer. Trail was snow covered and deep in places. No ice but should wear micro spikes

One of my favorite trails, it seems it is less crowded than some of the others in this area. Hiked 1/13, went up Gregory Canyon and down via Saddle Rock. The top was mostly hard packed snow and the bottom a little icy, I wore my microspikes the whole time and was glad I had them. Took me about 4 hours round trip. Would highly recommend!

Great hike and definitely doable and safe for children. I did see the same pit bull the lady below complained about today. It was super friendly and gentle. Unlike her I didn’t see a single pile of poop so not sure if she was looking in the trash or what lol.

Extremely unsafe trail to bring younger children due to lack of enforcement of off leash dog rules. There are literally hundreds of piles of dog excrement within a few short miles.
I can no longer bring my nephew here after we were rushed by an off leash pit bull. Of course the owner thought it was funny. Dog owners in Boulder County are the most entitled and ignorant bunch of people you will ever encounter.

Beautiful winter hike with amazing views.

We did this on New Year's Day after fresh snow and the views were absolutely stunning. My favorite Boulder trail that week. Added the Chapman loop to it.

a challenging hike especially if you’re not used to the elevation. Incline right away and pretty much the whole time, but definitely worth it.

Amazing trail! The person who commented three below me is correct- there is no trail labeled "Super Betasso" but the other trails are well marked. Just went today and small spots of ice but nothing serious. We will be back!

Enjoyed this for a leisure hike. We went in the evening to peak at night and the night views and star gazing were really cool. The paths can be icy, especially at night. Avoided the crowds by going at night.

Definetly the hardest hike I’ve been on, bring lots of water and a small snack. If you’re from the Midwest like myself be prepared for the elevation difference, lots of yawns.

Super fun road easy trail for all vehicles. Barely any snow 1-9-19 there is a off shoot at the very end if you go on it it is definitely a hard trail
