From mid-September through October, Snowmass’ mountain beauty gradually shifts from bluebird skies and wildflowers to swaths of leaves glittering gold in the crisp mountain air. The best way to experience the phenomenon is on foot or bike along Snowmass’ endless trails that weave through some of the most picturesque aspen groves in Colorado. It’s a spectacular time of year to be in the mountains and we invite you to take it all in here in Snowmass.
