The Connecticut College Arboretum provides a welcome connection with the natural world, offering opportunities for teaching, research, conservation, recreation and public education. 

The Arboretum's Native Plant Collection, Caroline Black Garden, Campus Landscape and Natural Areas are open to the public every day of the year from dawn to dusk. 
The crosswalk connecting the Arboretum to Connecticut College campus is finally happening! Williams Street is scheduled to be closed to vehicle traffic through August 6, 2021.  The main pedestrian entrances on Williams Street will remain open.  An alternative during this time is parking at 33 Gallows Lane and using our pedestrian gate just to the left of our garage at 46 Gallows Lane.
