The Connecticut Audubon Society’s Center at Fairfield is a hub of environmental education activities and events throughout the year. The Center adjoins the 155-acre Roy and Margot Larsen Wildlife Sanctuary, a nature preserve serving as an extensive outdoor classroom for school, summer camp, scouting, and adult education and conservation programs. Seven miles of walking trails, raised boardwalks and bridges offer access to the varied land, forest and freshwater ecosystems. The grounds also feature a butterfly garden and Birds of Prey compound. Trails are open to the public year round, seven days a week, from dawn to dusk. The Center building houses classrooms, live education animals and exhibits, and the Nature Store.
