Is the Island Explorer shuttle accessible from the Bar Harbor Motel?

Yes. It stops right in front of the Bar Harbor Motel every 15 minutes from the end of June until the middle of October and takes you to downtown Bar Harbor. If your destination is downtown, brilliant, you’re there. If you wish to go further afield other buses available downtown can take you all over Mount Desert Island and into Acadia National Park.
