The Arboretum serves a multitude of functions for the College and the greater New London community.

For students, the Arboretum provides a welcome connection with the natural world, a place to get away for recreation and reflection.

For the College's academic program, especially botany, biological sciences, and environmental studies, the Arboretum is a living laboratory just a few steps from the classrooms and residence halls. Generations of faculty and students have used the forests, meadows and wetlands for teaching and research.

The Arboretum consists of over 750 acres of Plant Collections including the Native Plant Collection, the Caroline Black Garden, Campus Landscape and Greenhouse and Natural Areas including Mamacoke Island and Bolleswood. All areas are open to the public every day from sunrise to sunset. All trails are suitable for hiking or casual strolling; limited areas are available for running.

Youth Groups (Arbo Project Tours)

Students from Connecticut College lead tours for school-aged children in the Arboretum's Native Plant Collection from mid-September to early November and from the last week in March until the first week in May. (If you would like to visit between May and September, our docents may be available to lead tours.) The tour runs for approximately one hour and covers topics such as changing seasons, plant life cycles, ecology and environmental conservation. The possibility also exists to tailor a tour to include specific topics being discussed in your classroom.

Arbo Project tours are offered free of charge. We prefer to keep groups to a maximum of forty students with one Connecticut College student guide for every ten students.
