A couple scrambles but a pretty moderate hike. Worth going up!

Awesome hike. Gets steep, but taken slowly is a blast. Dog was with me and she did great. Went right as the sun was coming up to avoid full weekend hiking trails.

Very crowded but great workout, short and sweet. Great views, especially if you go around behind.

More on the moderate/hard side. Steady incline but the short distance makes it easier. Perfect, quick hike!

A fairly easy trail, with a bit of rock scrambling here and there. The views are beautiful and the trail is well marked. I would suggest trekking poles for those with balance issues or knee problems, and a can of Boost or comparable oxygen would come in very handy for those who haven't acclimated. I came from sea level and did the hike the day after landing, so acclimation was a bit of an issue for me. The oxygen really helped.

Great hike!! Did this with my 9-year-old this morning. Would rate as moderate-hard. It was very windy at the top. Great views and fun terrain.

Going up I'd say is moderate to hard, there's a couple sections where you have to climb some boulders, nothing too treacherous. At the very top there are some great views of the 14'ers. However, avoid continuing your hike down the back of the Flatirons. That is not an officially sanctioned trail. I unfortunately slid 15 feet and got tons of road rash and a small break in my big toe. The trail on here is great, just please be weary of climbing down the backside of the flatiron unless you're very experienced and have proper gear.

Pretty Nice hike, although there are a ton of people even on a week day. I wouldn’t classify it as “hard” more intermediate. Beautiful spots to stop and checkout throughout the hike.

I didn't think this trail was hard at all, as I hiked it quickly without any trouble. great views, and had a lot of people on the trail.

Great hike - I've done it twice when visiting CO. It's a short distance but non-stop incline. Pretty rocky and it's been crowded both times we've come. Make sure you keep going all the way to the backside....beautiful views!
