Westborough, MA → Bar Harbor, ME

Your journey from Westborough to Bar Harbor spans roughly 226 miles of classic New England driving, taking approximately four and a half hours when conditions are favorable. The route primarily follows Interstate 190 north out of Westborough before connecting to I-91, which you'll take through central Massachusetts and Connecticut into Vermont. Once you reach the Vermont-New Hampshire border, you'll merge onto I-89 north, which becomes your primary corridor as you climb gradually toward Maine. The final stretch transitions you onto US Route 2 eastbound, which carries you through some of Maine's most picturesque countryside before you reach the coastal town of Bar Harbor on Mount Desert Island.

The terrain gradually transforms as you progress northward, starting with the rolling hills of central Massachusetts and transitioning into the more pronounced elevation changes of Vermont and New Hampshire's foothills. You'll notice the landscape becoming progressively more forested and rural as urban areas give way to dense woodlands, particularly once you cross into Vermont. The White Mountains region creates subtle but noticeable elevation changes, though this route avoids the most extreme grades by staying primarily on major interstates. As you approach Maine on US Route 2, the terrain flattens slightly while becoming increasingly scenic, with glimpses of mountains, lakes, and evergreen forests that signal your approach to the Maine coast.

Notable passing points include the city of Brattleboro, Vermont, where I-91 offers a chance to stretch your legs, and later the charming town of Littleton, New Hampshire, positioned near the White Mountains. From there, US Route 2 carries you through small New England towns before you reach the Gateway to Acadia region, where dramatic coastal and mountain scenery announces your arrival near Bar Harbor. This drive is most enjoyable during late spring through early fall, when weather is stable and foliage ranges from vibrant summer green to spectacular autumn colors. Winter driving on this route requires caution due to snow and ice, particularly in Vermont and New Hampshire's elevated sections, while spring can bring unpredictable conditions as mountain snow melts.
