The Aspen Center for Environmental Studies is a 22-acre (10-hectare) wildlife sanctuary that hugs the Roaring Fork River. With a mission to advance ‘the ethic that the earth must be respected and nurtured,’ the center’s naturalists provide summertime guided walks, raptor demonstrations and special programs for youngsters.
In the winter snowshoe tours are available in various locations and its weekly slide shows may give you some respite from the frigid outdoors. You can take a self-guided tour of the preserve surrounding Hallam Lake. There are three other locations in the region.
