The Colorado Year Round Outdoor Guide
This easy route up a Boulder landmark offers a fantastic panorama of over 100 miles of the Continental Divide. There are several “Green Mountains” in Colorado. This one, overlooking Boulder from the west, is a local landmark and a popular hike. The route described here is the easiest of several ways to the top and it is a good route to take up kids or visitors from out of town. Despite the modest effort, the fantastic panoramic view from the summit takes in over 100 miles of the Continental Divide, from Longs Peak in the north, through the Indian Peaks section, to Grays and Torreys Peaks to the south.
The first part of the hike is an effortless stroll through open stands of ponderosa pine. But your breathing rate will go up as the trail steepens considerably over the final 0.25 mile of switchbacks. Unleashed dogs, under voice and sight control, are allowed on the West Ridge Trail. There is a day use fee for non-Boulder County residents for trailheads in Gregory Canyon and along the Flagstaff Road. The fee can be paid at six self-serve stations situated along the Flagstaff Road. However, you can avoid the fee by parking beyond the park boundary, 25 yards south of the trailhead sign on the right (west) side of the road.
