Awesome views

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!

Great little hike. I would also agree that it's on the top end of easy. It is clearly bear country. Thick shubbery abound. Great forest areas. I saw a bear with her cub along the Connector. First time I saw wild black bears. Amazing experience.

Majestic arch!!!

Beautiful hike! Long one with heavily trafficked trail.

Good hike...go early as it gets busy with hikers. make sure you wear your hiking boots. it's a bit rocky in places.

Great hike. Some steep parts, but overall pretty easy!

Great and easy trail with lots of wildlife. Saw three deer, two bucks. Also, encountered two bears with a baby cub being one of them. Will post photos.

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.

Easy hike and wildlife viewing opportunities. We saw a bear with 3 cubs and deer the day we went.

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.

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

Absolutely amazing trail. One of my favorites this far! Plenty of challange for the moderate hiker while still being able to have an easy setting for the beginning hiker. Beautiful views the whole trip. I can't wait to go again.

Not too crowded if you start before 830.

Beautiful easy hike

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.

Fantastic for a short hike, quick elevation with a family!

Nice short and relatively easy hike! Took us 45 min to get to the cave. The views from boulders are great.

All uphill, very crowded, pay for parking

So beautiful and has a variety of inclines and declines which could be challenging. Definitely a work out and a beautiful sight. My favorite so far.

Perfect for younger children. Nice rocks to climb about half wayin. My grandchildren ages 4 and 6 loved it.

Wonderful hike. A little steeper then we anticipated but my 5 year old rocked it.

I’ve never had this issue with an All Trails trail before. We followed exactly where the trail was to be and it was not there. We wandered around and finally picked it up. Looks like some work needs to be done on this one

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!

The Arch at the end is a real treat - it’s incredible that the rocks formed together like that. We are Boulder locals and it took us 1 hour to get up and about 45 mins to get down. I would consider this moderate, but perhaps hard for someone not used to the elevation. The mere fact that you have to hike downhill then back uphill towards the end of the hike is pretty brutal! Well worth it :-)
