Highly recommend. More moderate than difficult, not too long, and with a great payoff at the top. Boots with ankle support aren’t necessary but beneficial. If you want to hike this in winter, bring your snow spikes

For bike riding this trail is a bit dull

Very nice walk! But I got caught on a path with a bunch of cows and had to google what to do in the circumstance to not anger them. Some signage about how to properly approach/avoid cattle when blocking a path would be appreciated!

Our favorite hike to hate! literally kicks your butt in the best way possible with an amazing view at the top... worth all the cuss words and pain during. Stats are a little off because I forgot to turn my tracker back on after we ate. Missed about an 1.5 hr segment on the descent. The rocky vertical part haha.

Easy hike for a moderate casual hiker. It only gets tough and scrambly on rocks the last 15% of the hike. Well marked and a great view at the top. Trail is still in good condition as I hiked this a few days ago.

Did this hike two years ago and it was well worth it. A bit difficult in certain areas but mostly a moderate hike. We got caught in a Thunderstorm, which was cool and terrifying. Definitely recommend this hike if you're in the Boulder area.

This trail is the single best workout in the entire boulder area. I’ll tell’ya why! It always has parking on mapleton and there’s plenty of room to pass people at any point. The easiest access to 1200 ft change in elevation. With friendly regulars!

Too tame for me... but it was pleasant enough.

Pretty good, but busy. I enjoyed it.

Well maintained trail, although a little rocky at times. Went around sunset and ran into a few people but wasn't crowded at all! Definitely gets your heart rate up if your a newbie to hiking like me, but otherwise enjoyable. I did come across two discarded doggie bags in the middle of the trail, not a fun surprise!

Fun trail, goes by faster than you think, the top is a great place to eat a peanut butter and jelly sandwich, also got a great panoramic picture at the top. Recommend it.

Great hike. Shaded in parts. Fun to see climbers doing their thing. Great views at the top. Parking is limited.

Definitely not hard as the rating suggests. It’s pretty crowded on the weekends, but that’s to be expected so close to boulder. Also, we saw plenty of deer going up and down!

Snow today on the trail 2" in some parts with starting of drifts. Great trail tight towards the end when it just stops due to a land slide. awesome drive in the light snow

It's hard, but worth it. I think it's longer than AllTrails shows.

Ran the clockwise loop. The creek was really beautiful! The last one mile was tough for me because of the climb and also since I hadn’t acclimated to the CO altitude.

Pretty crowded on nice days. Great hike otherwise!

Great little hike I did with my dog! I ended up going too far accidentally and ended up on Mesa trail so I took fern canyon to shanahan Mesa for some extra exercise. Was not strenuous but def got the heart rate up! Plenty of other hikers and lots of dogs.
