Admission & Hours

The Acton Arboretum is open every day of the year and is a free, public conservation land. Please read Acton conservation land rules here, and check out our FAQ.

All conservation lands in Acton, including the Arboretum, are open from “dawn to dusk”—specifically, from one hour before sunrise to one hour after sunset. Police take notice. Please plan visits accordingly.

Please do not visit conservation lands after dark, so that public safety personnel can dedicate critical time to emergencies. Thank you!
