The First Flatiron stands as one of Boulder's most recognizable and beloved natural landmarks. Part of a series of five numbered Flatirons, this imposing sandstone formation rises dramatically from the city's western edge, offering a stunning backdrop to the Boulder skyline. The Flatirons are not only visually striking but also provide a range of recreational opportunities, from hiking and rock climbing to simply enjoying the scenic beauty of the area.

From the top, hikers can gaze out over the city of Boulder, the vast plains stretching eastward, and the majestic peaks of the Continental Divide to the west. Beyond its natural beauty, the First Flatiron holds a special place in Boulder's cultural identity. It's a symbol of the city's outdoor lifestyle and its close connection to the surrounding natural environment. The Flatirons frequently appear in local art, photography, and advertising, solidifying their status as a defining feature of Boulder.
