Winter Programs

During the winter, daily programs include naturalist-guided snowshoe tours on top of Aspen Mountain, at Snowmass and at Ashcroft; naturalist-guided ski tours at Snowmass; and weekly slideshows where local adventurers and biologists share tales of adventures abroad. ACES' interpretive programs on top of Aspen Mountain helped garner the prestigious Golden Eagle Award for the Aspen Skiing Company.

Year-round on-site naturalists are available to provide information about nature and wildlife at our Hallam Lake Nature Preserve in Aspen; care for ACES resident, non-releasable birds of prey; perform wildlife rehabilitation duties; interact with visitors; and give tours of the Hallam Lake Nature Preserve.
