Connecticut College Arboretum

Southeastern Connecticut


More than 750 acres of native plants, ornamentals and trees from around the world are spread over this college campus. Free guided tours happen at 10am on the first and third Sunday of the month, April to November, at Olin Science Center, and there are also self-guided tours via an app. Two hundred acres have been left completely undisturbed as hemlock/oak forest and tidal marsh.
