Thorne has two outdoor education facilities in the Boulder/Denver Metro area at Sombrero Marsh in Boulder and Waterton Canyon in Littleton. Thorne’s administrative offices are located at the Sombrero Marsh Environmental Education Center in Boulder.
Sombrero Marsh Environmental Education Center and Thorne Administrative Offices, Boulder
Thorne operates the Sombrero Marsh Environmental Education Center in partnership with the City of Boulder Open Space and Mountain Parks Department and the Boulder Valley School District. Dramatic views of Boulder’s Flatirons provide a back drop for the Center’s .5 mile trail system which accesses a boardwalk and bird viewing blind where visitors young and old can get close to and explore a salt marsh ecosystem. Facilities at the center include a classroom, laboratory, mini-wetland, and bird banding stations. The trails and open space are open to the public daily. Visitors wanting to view indoor exhibits or borrow dip nets or binoculars for their outdoor explorations can visit from 1-5 PM on Mondays and Tuesdays (excluding holidays).

The Kassler Center, Littleton
Thorne offers programming in Littleton out of the Kassler Center through a partnership with Denver Water. The Center is located nearby Chatfield State Park at the entrance to Waterton Cayon. Environmental Education facilities at the Center include a classroom and the Rocky Mountain Land Library, which is a collection of 1,500 nature related books. While, these facilities are used exclusively for Thorne and Rocky Mountain Land Library programming and are otherwise closed to the public, we strongly encourage visitors to make use of nearby hiking and biking trails and explore the wonders of nature that exist amidst the areas rivers, streams, ponds, grasslands and forests.
