went bc bear peak trail was closed (signs that thru december certain trails off the south mesa trail will be intermittently closed. in our case there were workers who said itd be 30 mins - 1hr before it reopened. rather than wait we did mallory cave). two days after snow so was muddy for certain bits. climbed a few rocks and was rewarded with beautiful views. there’s a really nice vista point where we sat on rocks and had lunch before continuing on to the scramble...we don’t rock climb and were a bit scared but there’s a rope for the trickier part of it, just go slow and watch where you’re putting your hands & feet, you’ll be fine :)

Great fairly easy climb through fir forest followed by a challenging rocky decent. Overall very nice 2-3 hour hike.

Did this trail yesterday around 1:30pm. Definitely a lot of stairs which made the trail such a good workout. There was some snow that was still melting on the rocks but it was definitely manageable to get by without feeling like you may slip. The shade definitely helped with the elevation gain. Would recommend :)

Really great easy hike! It was a short hike up and down, it was rocky and uphill but very easy. We went on a Sunday afternoon and it wasn’t busy at all! Highly recommend for anyone wanting a quick hike with great views!

Definitely rated appropriately as hard. First 3 miles were at a seriously incline. Beautiful views at various points making good spots to grab some water. Climb 2500 ft to reach summit, which is a great 360 view. Pack plenty of water and would suggest a snack along the way. Would recommend for those ready for change in elevation, terrain and temperature. Encountered snow and ice at various points, making the trail more difficult. Overall, great hike and beautiful views.

Great Boulder hike. Definitely a stinger for 3.2 miles. Agree the way to go is clockwise and the East ridge descent involves about .5 of bouldering until the trail levels out. Found parking along the road at 10:30am. Shocked since this is a very popular trail.

This is a great moderate trail for those who 1. Just got off the Cheeseburger diet; 2. Have recently started a new exercise plan; and 3. Have not visited Colorado (or another higher altitude state recently) and need to readjust to it (by the way, all three apply to me). That being said, I loved ithis hike because it challenged me at the end for the aforementioned reasons due to the last quarter mile or so basically turning into a rock climbing expedition. The top was great with a nice view of the snow capped Rocky Mountains and sweet breeze. I’m sure if I lived in Colorado and hiked here exclusively it would have been much easier but I finished up and back with no issues (thanks to a few breaks!). The hike back would almost classify as “easy” due to its constant decline.

We hiked this early today (Sunday), and by the time we made it back, there were quite a few mountain bikers on the trail, and the lot was full. Probably a more pleasant hike on a day without bikers. I would say it’s much easier than moderate. I was coming off an ankle injury and had no issues with the trail as it’s pretty flat and even. Only a few inclines, and they’re not steep. Pretty standard Boulder views. Nice, easy trail but nothing to write home about.

It starts out pretty easy, but be warned, this hike is hard! It’s a steady increase in steepness all the way to the top and we were exhausted after the first set of switchbacks once we got to the ridge. We didn’t actually make it to the top, but turned right at the ridge and just got the Coach Class view of Boulder.

Going to Chautauqua in August around 9 am, you can expect the trail to be crowded. It gets harder as you go, with the switchbacks being the peak hard part, and you have to make a few “hope this works” decisions about what combination of named trails to take. The trail also gets a little confusing at the first overlook. It’s obvious it’s not the end but you have to bend left around it to be back on your way to the Arch... which will make you thankful there’s so many people to follow after all!

Great hike for those brief 2 weeks of Fall in Colorado when the weather’s too cold to hike in a shaded area... or when you’re just feeling a “lazy workout.” Saw prairie dogs and deer; no mountain bikers. Started hiking at 2 pm and the parking lot was about 3/4 full - you’ll be fine. Also the gate might appear chained, but it’s not - it’s just looked around the top.

Took new Mesa trail cutoff ( under construction). Great new route avoiding wetlands and up/down steps.

A very good trail. Clockwise makes it largely a gradual uphill, good work out. I enjoyed the creek very much.

Very dangerous when icey. Ended up dislocating my knee on the way down... Shouldve been wearing better shoes for the ice. The loop itself is 5.7 miles but if you start where the hike suggests from the parking lot, it ends up being 7. Clockwise was definitely the better way to do it.... but gosh that ice was intense. Gorgeous views at the top, will try again when it's not snowy and icey
