Why Royal Arch Trail Is So Popular
Royal Arch Trail stands out because it combines accessibility, challenge, and unforgettable scenery all in one hike. Within minutes of leaving the trailhead, hikers move from the lively atmosphere of Chautauqua into pine forests, rocky staircases, and towering sandstone cliffs beneath the Flatirons.
The hike begins near the ranger cottage at the Chautauqua Trailhead off Baseline Road. Most hikers start on the Bluebell Trail before connecting to Royal Arch Trail shortly after entering the forest.
