Winter & Spring Programs

During the winter months, ACES offers a variety of daily programs at spectacular locations around Aspen. Join an ACES Naturalist for daily guided snowshoe tours on top of Aspen Mountain, at Snowmass, and at Ashcroft, or hop on a Naturalist-guided ski tour at Snowmass. On Friday evenings ACES offers snowshoe tours at Snowmass as part of Aspen/Snowmass' Ullr nights! From January through March head down to Hallam Lake for weekly slide show series where local adventurers share tales from abroad at Potbelly Perspectives on Wednesday evenings and regional experts share their knowledge of relevant naturalist topics at Naturalist Nights on Thursday evenings. Visit our sites, featuring free admission during open hours and staff available to answer any questions and show you around! Hallam Lake boast a plethora of education animals including our three birds of prey. Rock Bottom Ranch farmyard tours are offered Wednesdays and Fridays at 11AM.

If you have a particular adventure in mind our Hire a Guide program offers many options for private, custom programs with interpretive, first-aid trained guides.
