Travel north up I-95 towards Bangor until Exit 182A, then briefly follow I-395 until Exit 6A leads you on to Route 1A and south 22 miles to Ellsworth and then onwards via Route 3 to Trenton. Alternatively, drive the old but more scenic Route 1 all the way up the Maine coast to Ellsworth, or take I-95 to Exit 113 just north of Augusta and pick up Route 3 there. To continue south beyond Trenton, follow the signs towards Bar Harbor and Acadia National Park; a causeway connects Trenton with Mount Desert Island.
