Heads up - tried to hike on Wednesday October 19 and there was a sign for closures on Wednesdays and Thursdays due to trail overuse.
Pretty awesome and can be done in a short amount of time. We went up the trail to the second flatiron in about an hour but didn't have time to do the first being we had to be at the airport. Will for sure go back
Just finished this hike, wasn't too bad at all. The views are wonderful. However it's a high traffic trail, which makes it difficult to find your zen. Overall it's a great morning hike.
Beautiful trail very rewarding
Great hike! Nice crew rebuilding the trail.
Very crowded and lots of impacted areas from people cutting the switchbacks but a beautiful area none the less
Great trail! Went up on a Saturday morning. Pretty crowded but everyone was super nice! Boulder is making repairs so the trail is closed two days per week. Make sure to check the signs on the bottom before you go up.
Challenging, but well worth it!
Fun, but steep hike. Lots of beautiful views of CU Boulder and downtown Denver as you ascend. There are some areas of exposure and shade, but more importantly, watch your step as you reach the boulder fields. The trail is definitely packed on the weekends, so just go at off-times (sunrise/set, winter, etc) and you'll be fine.
Beautiful little hike
it was a lovely challenge and a beautiful view at the top!
We did the second Flatiron and it was great. Awesome views when you get to the top. Challenging going up at some points, but a great hike. Worth it for the views.
Amazing sunset hike but extremely crowded. It is a short little hike but worth the views!
Great hike! I enjoyed the rocks & the views!
Nice hike. Good views. Short, but steep. ALWAYS will be crowded. Dog friendly
