Wyoming Wanderers: Boulder Flatirons
The First and Second Flatiron trail in Boulder Open Space in Boulder, Colorado, is 3.6 miles and has views of Boulder, the mountains and the Flatirons all the way up. There are five main Flatiron formations called the first, second, third, fourth and fifth, and a hundred more scattered on the slopes with different names like Satan’s Slab.
