The trail to Royal Arch is one of the most popular in Boulder, thanks to its easy access and beautiful views. The run begins at the Bluebell trailhead on the edge of town, heading into the Flatirons to reach a natural stone arch—an eroded outcrop of the Fountain Formation. You'll also get to check out Tangen Spring and a small cave, adding a little extra exploration to the adventure.

Description

While the approach is easy, as the trail enters the Flatirons, it traverses some fairly challenging terrain, including loose rocks, tight switchbacks, and large steps. While popular, this is far from the easiest trail in Boulder. Come prepared for a bit of a challenge!
