Estimated Driving Time

  • Exit onto Route 3 East near Augusta or U.S. Route 1 North for a more scenic drive through coastal towns
  • Route 3 takes you directly to Mount Desert Island and Bar Harbor, the gateway to Acadia National Park

This route combines efficient highway travel with opportunities to explore charming towns along the way if time allows.

Scenic Coastal Route Option

For a more leisurely and picturesque journey, travelers can opt for U.S. Route 1 North, which hugs the coastline and passes through iconic Maine towns such as Brunswick, Bath, Wiscasset, Damariscotta, Rockland, Camden, and Belfast. While this route can extend travel time to 4.5 to 5 hours or more, it offers a rich experience of Maine’s coastal charm, local dining, and photo-worthy landscapes.

Road Conditions and Seasonal Considerations

Road conditions are generally good throughout the year, but travelers should be cautious during winter months (December through March), when snow and ice can make certain portions of the drive—especially rural or coastal segments—more challenging. Summer and early fall are the most popular times to travel, offering clear roads and vibrant scenery, particularly during Maine’s foliage season in late September and October.

Fuel and Rest Stops

There are ample opportunities for fuel, rest, and refreshments along the way, particularly when traveling through larger towns like Augusta, Rockland, and Ellsworth. Many of these communities offer visitor-friendly amenities, making them ideal spots for breaks or overnight stays if you're splitting the trip.

  • GPS and smartphone apps like Google Maps or Waze are reliable for routing and real-time traffic updates.
  • Cellular service is generally strong along the main highways but may be spotty in remote or wooded areas off U.S. Route 1 or near Acadia.
  • Keep a physical map or road atlas on hand if you plan to explore less-traveled backroads or state parks.

Whether you're aiming for a quick drive or a scenic road trip experience, understanding the route and distance from Portland to Acadia National Park helps ensure a smooth and enjoyable journey.
