Mt Sanitas Loop Trail - 3.1 Miles Round-Trip

Tectonic forces along northern Colorado's front range created ripples that forced rock layers to bulge and compress, creating anticlines - or convex folds on the earth's surface. As the bulging anticlines' softer sediments eroded, only hard ridges - known as Hogbacks - remained from previously rounded hilltops between the eastern plains and Rocky Mountain uplift.

Mt Sanitas is one such formation that stands above all others in central Boulder, Colorado.

The Mt Sanitas West Ridge Trail and Sanitas Valley Trail form a short but challenging loop to its rugged summit, and along its east face. The following description begins on Mapleton Road and travels clockwise from the West Ridge to Sanitas Valley Trail:

Cross the bridge and turn left twice to pick up the Mt Sanitas West Ridge Trail. The trail climbs steeply and ruggedly for .85 miles before moderating on a thin ridge with good southwest views across Sunshine Canyon and Chautauqua Park.

It bends north on the final approach to the Mt Sanitas summit (1.2 miles : 6,843'). Space is limited, but easy to maneuver about for panoramas of the foothills, plains and Continental Divide.

The trail continues north and drops abruptly down rugged, tightly-wound switchbacks. You'll negotiate several sparingly marked switchbacks through car-sized boulders (1.4 miles) before turning sharply south (1.65 miles).

The trail edges back east through open space to the Sanitas Valley Trail (1.95 miles : 6,080'). This wide fire road glides gently south between Dakota Ridge and the east face of Sanitas.The Sanitas Valley Trail completes the loop and leads back to all parking areas on Mapleton Road.

Extend travel by diverting on and off one of three spurs for the adjacent Dakota Ridge Trail.

"Hi you're directions to the Mt. Sanitas TH are incorrect. The trailhead is actually on Mapleton Avenue in Boulder, not Mapleton Road. And it's behind the Mapleton Memorial Hospital, not the Mapleton Medical Center. I bring this up because if you do a Google search for either Mapleton Road or the Medical Center you don't get any results. "
