The world-famous Flatirons rise dramatically from the west edge of Boulder, Colorado forming an iconic backdrop. Protected as the center piece of Boulder’s Open Space Mountain Park, the Flatirons include dozens of major rock formations and hundreds of climbs of all types, with the steep ravines and wooded slopes of Green Mountain and Bear Peak forming a veritable wilderness abutting the city.

The First Flatiron is composed of sandstone with excellent flakes and face holds, with a rating of a moderate 5.7. Varying between obscure boulders and slabs scattered with technical summits, the Flatirons are considered some of America’s most iconic and classic climbs and are deeply woven into the history of rock climbing.
