Kennebunkport to Princeton Road Trip: Coastal to Academic Charm

Did you know that the stretch of I-95 between Portland, ME and Boston, MA is one of the oldest continuously used highway corridors in the US, originally following the Post Road established in 1673? This road trip from Kennebunkport, ME to Princeton, NJ covers roughly 350 miles and takes about 6 to 7 hours of pure driving time, but smart travelers budget two to three days to explore the rich tapestry of coastal Maine, historic Massachusetts, and the rolling hills of New Jersey.

You'll traverse through Portland's working waterfront, cross the Piscataqua River into New Hampshire, and eventually hit the Boston metro area before heading southwest through Connecticut and into New Jersey's Princeton.
