Aspen Center for Environmental Studies

The Aspen Center for Environmental Studies (ACES) has four locations situated in the Roaring Fork and Frying Pan Valleys dedicated to promoting an awareness of our relationship to the environment. They offer community garden space at their Hallam Lake and Rock Bottom Ranch locations during the summer. And during the winter, their winter naturalists provide a window into mountain ecology by guiding visitors on snowshoe tours on Snowmass Mountain, Aspen Mountain, and at Ashcroft. ACES also offers school programs to cultivate an understanding and love for the natural world in the younger set. Also, they invite guest speakers to give informative and educational talks, known as Naturalist Nights, on topics ranging from hydrology, forest health, birds, land ethics, and beavers. The Aspen area has a lot to offer, and so does ACES in terms of interpreting and connecting with all the natural splendor of this spectacular place.
