Boulder’s Royal Arch: A Natural Wonder Framed in Blue Skies
Boulder’s Picture of the Day: The Iconic Royal Arch in Full Glory
Today’s outdoor picture of the day captures one of Boulder’s most legendary landmarks—the Royal Arch—framed by a brilliant blue sky and soft, white clouds. Located in the scenic foothills of the Flatirons, this natural stone archway stands as a timeless monument to the geological beauty and hiking spirit of Boulder, Colorado. With the sun lighting up the sandstone and the open arch revealing the sky beyond, this is one of those moments that stops you in your tracks.
A Bit of History Behind the Arch
The Royal Arch was formed over millions of years through natural erosion in the Fountain Formation, the same ancient red sandstone that shapes the Flatirons themselves. The arch is estimated to be more than 300 million years old and has become a symbol of Boulder’s outdoor charm. While it’s not man-made, the arch has an almost cathedral-like grandeur—hence the name “Royal.” It’s one of the most photographed geological features in the city and a bucket-list hike for locals and visitors alike.
