Green Mountain Professional Review and Guide

"It is a rather intense ascent, climbing just shy of 2,300 feet in about 3 miles, and often feels like going up an odd assortment of stairs. Yet, there is something alluring about the pure effort it requires. Green’s rather relentless grade lulls the brain, and attracts top athletes from a number of disciplines who make it part of their regular training regimens."

"Rising impressively along the Front Range, the Flatirons provide a dramatic backdrop for the city of Boulder. They also form the centerpiece for the beautiful and surprisingly wild Boulder Mountain Park.

With many miles of backcountry trails, this park is also a worthwhile destination for hikers. A good and challenging route explores Gregory Canyon along a loop that follows three different trails. Collectively, the entire hike constitutes the Green Mountain Loop."

"There are twenty peaks called Green Mountain in Colorado and this one is locally famous for its many butterflies. It is slightly behind (west of) the Flatirons, Boulder’s signature mountains, and can be reached via several trails.

This variation is a strenuous loop. There is a creek about halfway into the hike, but it is best to bring water along for your canine companion. It is also best to hike this loop early in the day to avoid being caught in a thunderstorm."

We took the cutoff trail which made it a nice 3 mile loop, finishing in 2.5 hours. Took recommended direction - this 55 year old recommends hiking poles for the down portion or your knees will get beat up. A great hike with outstanding views of Boulder plus the Denver airport.

This was a beautiful trail. We took it the opposite way that was recommended, therefore got the steep hike out of the way first and relaxed on the easier part of the loop. Part if the trail allows dogs to be off leash, and our collie really enjoyed the coolness of the tree cover. Take water and make sure to stop at the lodge on the way down.

This is a great hike: a bit steep, but worth the effort to make it to the summit.
