“Very popular and scenic loop right from the edge of town.”— Nick Wilder
After several false summits, you finally gain the true summit and have unobstructed views of all of Boulder to the east, and partially obstructed views of foothills and Indian Peaks to the west.
Head down the very steep East Ridge Trail, which has several tricky sections of steep rock. It eases up as you descend, and finally widens and becomes much easier as you get to a saddle and intersection with the Sanitas Valley Trail.
As you descend this nice, easy gravel road, enjoy the spectacular views of the Flatirons, seen from a unique side-on angle. You'll pass the historic Silver Lake ditch (which supplies water to Boulder farmers and has been in use since the late 1800's) and soon end back where you started.
There is also an old quarry halfway up the slope (a spur trail will lead you there) that was used for several early University of Colorado buildings.
