You'll generally travel around the Blue Hill area by car, as public transportation in the Blue Hill area is nonexistent and the main grocery store, Tradewinds Marketplace, is most of a mile up a steep hill.
Traffic during the summer months is incredibly busy by Blue Hill standards, although seekers of solitude might want to visit from October to April, when the tourists and summer residents haven't come up yet.
There is a public transportation system serving Blue Hill and Hancock County. It is called Downeast Transportation. This service is offered Monday through Friday, to and from Ellsworth, the county seat. Connections can be made to other parts of the county-wide network.
