Colorado >> Grand County

The most popular skiing in Grand County may be found on the North side of Berthoud Pass. But if that's where you stop, you're missing the best skiing. There is great skiing to be had on the western slope of the ridge that makes up the Continental Divide, in the Fraser Experimental Forest, out West in the Williams Fork mountains, and north towards Willow Creek Pass and the Never Summer Range. The best part is that aside from Berthoud, you're unlikely to run into anyone else.
