Wow what an incredible hike! We did the Royal Arch Trail and then continued on the Blue Loop. Definitely difficult, it took us a little under an hour to hike to the Arch, we took minimal breaks. Enjoyed a PB&J at the top with the chipmunks who are overly friendly. (We did not feed them).

Good hiking and pretty busy when we went at the end of October. Trails are well marked and have maps scattered throughout. Flat irons were also just really fun, easy, climbs. We ended up climbing the 3rd and doing the 5th on the 2nd. Good park 👍

We hiked the smaller loop instead of the trek up the Flatirons. It’s an easy hike with a beautiful view of the mountains.

An area of outstanding natural beauty with well marked hiking trails, some of which are suitable to walk on even in snowy conditions. Not to be missed if you're in the area!!

Intermediate level; for beginners hike may seem intimidating as the incline begins pretty quickly from the trailhead, but keep going! The views are totally worth it. We took the Chautauqua trail-Flatiron 2/3 hike up and the Bluebird-Baird trail down. Enjoy the hike!
