  • Traveled through this area mostly by car, as I am a senior citizen w/ arthritis. Did get out and stretch a bit and the trail was smooth, and clean as a whistle. Beautiful views.  more »
  • This place is awesome in every way. I was very impressed with these majestic rocks and wish it would have been warmer. 23 degrees and wind made for a cold and short visit.  more »
  • The hike was challenging due to elevation and just from walking up hill for such a long time, from Texas so elevation was a bit more challenging. Beautiful hike and so glad we got to experience it on ...  more »

  • Beautiful views but trails were much more strenuous than some of the others we went on during our trip. That being said, it is less crowded than other mountains we hiked. I would recommend going early because we went later in the day and the sun started to set quick. Ended up having to hike down with the flashlight on our phones and we weren't the most experienced hikers.
  • Amazing trails and places to go and visit. Wear a Hat and Sunscreen! Great place to visit!!
  • Great place to hike! You might see some deer on the path too :)
  • Enjoyed running up the trail today! It was a beautiful day in the 40s-50s, and there were loads of runners, college students and families out hiking the trails today. I'll be frequently training for my trail marathons up there this summer!
  • I don't see how you don't give these amazing Flat Irons 5 Stars. This entire area is incredible and I highly recommend climbing the Flat Irons. You can hike to the top or climb them!
