I climbed Green Mountain many times. Great views on top of the snow-capped Indian Peaks and Longs Peak. A good trail, which you can also access from Flagstaff Mountain. I love climbing this mountain and next time I am in Colorado, I'm sure I'll take a nice trek out there.
Nice sunny winter day. Trail was a bit icy in places. Great views of the divide, Boulder, and the plains.
Also May 2004, June 2004, September 2004 via various routes. This is such a nice small mountain to hit when you don't have a lot of time or don't feel like driving up into the high country.
