This is a moderate intensity 3 to 5 hour trail depending on how rigorous vs. leisurely you want to be. I've hikded this trail in both directions. Ascending via Amphitheater is a steeper incline, and more gradual descent via Ranger and Gregory Canyon, compared to vice versa. I recommend this route if you're looking for a more challenging climb that's gentler on the knees coming down. There is plenty of shade and some open spaces. The view from the summit is beautiful.

A pretty constant ascent for most of the trail but the views are great and arch was so worth it! Though the elevation wasn't too high at the end, we had a little trouble with the altitude here since we're from the northeast (brought extra oxygen in case). Distance is not very long at all and was relieved that the descent was not super steep. Highly recommend this hike!

Rugged trail. Amazing views.

Majestic arch!!!

Beautiful hike! Long one with heavily trafficked trail.

Good workout, kinda shaded making it nice during summer heat. Great views from top.

It is worth it! It is not easy. It becomes Very steep and small tight switch backs. Don’t give up at Sentinal Pass. After this it’s kinda brutal because the pass is a treat too. It’s just a bit further and worth the entire stair master. A very rewarding hike. Great workout.

Great hike. Excellent views. Moderate in difficulty. Wouldn’t consider it to be very hard. I would definitely do his hike again.

Great hike. Not for beginners. My husband and I (late 50s) took about an hour to hike to the top and about 40 minutes to descend. Beautiful view from the arch.

T U F F. But worth it. Go early to avoid the crowds at the top, trail is fairly simple to follow except for when it’s not.

It's a beautiful hike, but like others have said, it was definitely strenuous. The payoff when you get to the peak is definitely worth it! Don't get discouraged!

Lots of stairs but beautiful view at the top! Not outrageously hard but still a good hike!

Really pretty quick hike. Easy to follow and well maintained trail!

Challenging with some nice portions of rock scrambling. Views at the top are a little obscured and trail is a busy. Definitely worth it though!

Not too crowded if you start before 830.

Hiked this trail with my wife and kids. Started raining which made everything slick, but when you make it to the top the views are amazing.

Good route, good views from top & a few other places, good weather today, good hike.

Spectacularly beautiful with varied terrain and a challenging ascent. Good work-out, mid-week not crowded and a well-marked trail. Saddle offers a nice spot for a break. Final segment rutty but accessible. We started at NCAR and went up Fern Canyon trail.

Short but rewarding trail. Easily marked. I’ve done this trail three times now and never had a problem with crowds. The elevation makes it harder.

Definitely challenging but still doable! Great views, fun hike but quick elevation gains.

A great trail! Beware that they modified the Walker Loop - I ended up walking up to another trailhead and taking another trail to meet back up with the Walker loop. Follow the "New Access" signs to save yourself some.e energy!

This hike is well worth the effort especially for some good views of the flatirons and front range. As you get closer to the top, the climb becomes more technical with boulders and loose rock, but nothing that an able-bodied human or canine can’t do. My pup and I ran most of the way until we hit the more technical sections and it was a blast! Highly recommended for those in the area but I can see how this hike can be dangerous if weather is hot and dry. Bring plenty of water esp. if you have a pup out there.

This hike is absolutely gorgeous! Watch for the mountain bikers. Crazy route but well worth it.

Even though it was a tough trail with a lot of stairs, it was completely worth it to see the beautiful skyline of Boulder. Loved that they had drinking fountains at the bottom too for humans and dogs! Trails could have been marked a little better and parking was difficult to find since we went on a weekend but again... totally worth it!

Awesome peak! The directions are a bit confusing, you actually start the hike at South Mesa Trail and then I used the map on here to see which way to go when the trail heads intersected. Definitely worth the hike to the top.

I agree with the other reviews— this is definitely a challenge, especially once you get past the graded trail section and start climbing up Shadow Canyon, where there is not a defined trail and you are primarily scrambling up rocks. There are no cairns to guide you, but the way up is fairly intuitive and other hikers coming down help show the way. The canyon section feels long because there seems to be no point of reference. Unlike climbing a 14er, there is no false summit much less a real summit as a visual goal. But keep going! The saddle between Bear Peak and South Boulder Peak features an otherworldly section of burned trees and it is very dramatic— the charred trees against the greens and yellows of the vegetation, the colors of the rock and the bright blue sky is spectacular. The climb up to South Boulder Peak is not bad and once you summit, the views are amazing. Loved seeing Longs Peak from that vantage point! The summit is great too if you are with someone you like sharing canned wine, olives, fruit, and homemade zucchini bread. The way down is tricky but the hike is well worth the effort!
