Summer Naturalist

Job Overview
Every year, ACES offers an intensive Summer Naturalist Internship program at ACES at Hallam Lake, our visitor center and 25-acre nature preserve in the heart of downtown Aspen. Summer Naturalists receive valuable training and experience while leading guided hikes and conducting environmental education programs at Aspen Mountain, Snowmass, the Maroon Bells, ACES sites at Hallam Lake, the Catto Center at Toklat and Rock Bottom Ranch, and at various other iconic locations around Aspen. Many of ACES employees first come to the organization through the Summer Naturalist position, including some of our small administrative staff.

The Summer Naturalist program has dual purpose. First, ACES aims to provide the best possible learning and working experience to Naturalists. The second goal is informative and inspiring educational interactions with ACES tour and class participants.

Since 1985, over 400 Naturalists have participated in this respected program, many moving on to meaningful careers as teachers, wildlife biologists, university professors, environmental lawyers, veterinarians, non-profit administrators, sustainability experts, and more.
