This 4-miler starts with a gentle climb along rolling ridgeline, then cranks it up a notch with an obstacle course of steep rock steps and tightly-spaced boulders.

At first glance, the 6,863-foot summit of Mount Sanitas may seem modest compared to the 8,000-foot peaks dotting the ridgeline west of Boulder, but this 4-mile hike (or trail run) packs plenty of punch for a short outing.
From the Mount Sanitas Trailhead at the west end of Mapleton Avenue, follow the gentle Sanitas Valley Trail to the north up the drainage. After 0.3 mile, turn right onto a dirt path that leads out of the drainage and connects with the Dakota Ridge Trail. Walk along a rolling ridge for the next mile to the base of Mount Sanitas. From here, you'll navigate a steep obstacle course of switchbacks, rock steps, and giant boulders (and pass expansive views overlooking Boulder). At Sanitas' small summit, take in expansive views of Boulder and the eastern plains before retracing your route back to the trailhead.
