Hallam Lake
Hallam Lake, a 25-acre nature preserve and environmental learning center, was the first location of the Aspen Center for Environmental Studies. The Hallam Lake property was donated in 1968 by Elizabeth Paepcke. The preserve is open to the public year-round and provides an inspiring setting for ACES’ many educational and naturalist programs. Borrow our binoculars and search for local wildlife. Keep your eyes out for freely roaming mule deer, elk, foxes, coyotes, bear, beavers, golden eagles, hawks, songbirds, and more!
Directions: We are located at the end of Puppy Smith Street behind the Aspen Post Office. You will reach a set of stone gates. The parking lot is on the left, and then you can walk down through the gates on the trail to the Hallam Lake Nature Center, which will be at the end of the trail on the left. Please call 970-925-5756 if you are lost!
