Royal Arch is an amazing geological formation perched high along the pointed peaks of the Boulder Flatirons. The arch has an opening of about 25 feet with the top of the arch rising close to 40 feet above its base.
The trail to the arch is a relatively short hike of three miles; however, the 1.5 miles up are very steep and thus the hike up is quite a workout. The final destination is a lovely rock arch with surrounding views of the Flatirons and the Boulder front range below.
In the springtime you will also be treated to a meadow full of wildflowers right at the base of the trail, which make for wonderful photo opportunities for the macro enthusiasts.
Note that the arch itself and the views from the top provide photographers with some truly spectacular images, but you should know that the hike up is relatively enclosed by trees and does not offer much along the way in terms of views.
This is not a hike for people out of shape. Even those used to hikes may have trouble if they are coming from a much lower altitude.
