Alerts & Updates

The Arboretum’s paths are clear but due to icy conditions some features may be closed.

Advance Tickets Required for All Visitors (Including Members)

The Morris Arboretum is excited to be open! We have instituted new policies as required by the government of Pennsylvania in order to keep the public safe while visiting. Please review the policies below before your visit.

  • Guests are to wear face coverings outdoors when in a more crowded/densely populated area where social distancing is difficult to maintain.
  • Face coverings must always be worn indoors.
  • If you feel sick, stay home.
  • The Visitor Center, Fernery, Log Cabin and The Shop are temporarily closed, but picnicking will be permitted in certain areas.
  • Restrooms are open and sanitized regularly.
  • Hand sanitizing stations throughout the Arboretum.
  • Bring your own water and snacks.
Reserve Tickets

Unfortunately, Out on a Limb will be closed on Wednesday, January 29th through Friday, January 31, 2020 due to scheduled maintenance.

The Garden Railway will not be operational from 2:00 PM Friday (July 19) through the weekend (July 20-21). The trains will open for normal operation on Monday, July 22nd. Our Train Master reported that the trains will not operate in the excessive heat, citing electrical, track and rolling stock failures.

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

Garden Railway trains are not running Saturday, September 8th and Sunday, September 9th due to inclement weather.

Please note: The Rose Garden is closed for maintenance every Thursday morning until noon.

Weather conditions may limit garden access to certain features even if the garden is open – please check the web site or call (215) 247-5777 for updates before visiting. Our visitors’ safety in the garden is our top priority. Therefore when inclement weather is predicted, we will make decisions about closing the garden accordingly.
