With four locations in the Roaring Fork Valley, the Aspen Center for Environmental Studies offers a wealth of opportunities to learn about the local environment year-round. From guided hikes and snowshoe tours to week-long camps to fun events for the whole family, ACES is the hub for environmental education in the region.

In Snowmass, ACES offers daily programming and naturalist-guided tours on Snowmass Mountain. In Aspen, you can visit ACES’ Hallam Lake, a 25-acre nature preserve in the heart of Aspen. Further downvalley is Rock Bottom Ranch, a working educational farm halfway between Basalt and Carbondale. If you have a particular adventure in mind, the special Hire-a-Guide program offers many options for private, custom programs with interpretive, first-aid trained guides.
