The Royal Arch trail is the highest rated hiking trail in Boulder, Colorado, according to AllTrails.

Royal Arch is a popular Boulder trail that leads to a natural stone arch with views of Boulder and the Flatirons. Loose rocks, tight switchbacks, and large steps will put a strain on your legs. This trail can be confusing and feel longer than it is, so bring a map and plenty of water. The trail is not directly accessible from a trailhead, but it can be reached via Bluebell Road (pedestrian access only) from the Chautauqua Trailhead.
