The Connecticut College Arboretum in New London, Connecticut, is a vast 750-acre area that combines botanical gardens, walking trails, and diverse natural habitats such as forests, wetlands, meadows, and even Mamacoke Island.

Established in 1931 as an educational and conservation space, it features several prominent collections including the Native Plant Collection—showcasing trees and shrubs native to eastern North America—and the Caroline Black Garden, which houses ornamental plants from around the world.

The arboretum functions as an outdoor classroom, living laboratory, and tranquil refuge for both campus and community, supporting research, ecological studies, and public education. Visitors enjoy well-maintained grounds, beautiful plant diversity, peaceful landscapes, and a welcoming connection to nature throughout the year.
