Hardest Hike in Boulder?

[LeJerk]

Not necessarily the longest in terms of time or distance. More like steep grades, rough terrain. What do you think?

No ropes, that's climbing to me

you can choose some challenging stuff in Chautauqua Park...for steep & rough, go straight up the flatirons...

You'll love the hike to the top of the first flatiron at Chautauqua, and if's it's a bit too tame to hike... trail run it!
