Construction Notice:

Parking Lot Closed September 21, 22 and 23.

Morris Arboretum’s parking lot is being repaved September 21, 22 and 23. Our parking lot is a demonstration lot for its sustainability. Installed 25 years ago as one of the first of its kind, the parking lot has filtered into the earth about 31,863,304 gallons of precipitation from the Wissahickon watershed. But the time has come for it to be renewed.

The entire parking lot will be closed September 21, 22 and 23. Auxiliary parking will be available at the bottom of the hill (near the kiosk) and shuttle service will be provided to the top of the hill. ADA access will be limited. No buses will be permitted beyond the kiosk.

We apologize for the inconvenience, but we are committed to keeping our parking lot sustainable and our visitors safe. Thanks for your patience.

The Arboretum is open as usual. Click here for hours.
