The Flatirons are definitely worth the visit, especially since they are easily accessible and free! There are a wide variety of trail types and loops here and they range in difficulty quite a bit. The areas makes for a great outdoor day, and even though certain spots tend to get crowded the proximity of the Flatirons to “civilization” makes them... More

Visited Denver last September and ended up heading to Boulder and The Flatirons for my first hike. It was incredible and it's definitely a must! Views are spectacular from wherever you are.

Our family of five (kids ages 6, 10, 13) hiked up to the Royal Arch today. We started at the trailhead by Baseline. Maybe the most beautiful trail I have hiked. Part woodland trail, part rock scramble. Truly a challenge for my six-year-old, but she made it and was very proud. Beautiful views from the top, both of the Flatirons... More

I climbed 1st Flatiron and the views from the top are just awesome. I also hiked around the 2nd and 3rd, and the Royal Arch. I recommend all of them.

This would be a wonderful and exceptional hike if it wasn't for us tourists - you are constantly walking behind or in front of someone or a family. There is eventually some distance you can get away but you will always be seeing and hearing someone. Took the car up and that was well worth the views and popping out... More

Great hiking with multiple trails and wonderful views of Boulder and beyond. Do watch out for an occasional rattle snake. Terrain is a bit up and down but the trails are well cleared.

We hiked through the Flatirons on our recent trip through Colorado. Fall is the best time to visit with the changing leaves and mild weather. Nederland is a great mountain town to visit.

spent several hours hiking the trails behind the N C A R building, good place to park and explore the trails from. Walked about 6.5 miles along the Mesa trail and some offshoot trails. Make sure you take plenty of water and sunscreen it can get hot and the air is thin!

Semi-strenuous hike. Great view at the top, make sure you wear comfortable shoes and bring plenty of water.
