A practical 9-day Maine coast road trip itinerary from Portland to Bar Harbor and Acadia, with the best stops, driving times and how to pace Route 1.
Maine's Route 1 is the East Coast's answer to a great ocean drive: roughly 165 miles of lighthouses, working harbours and lobster shacks running from Portland up to Bar Harbor and Acadia National Park. This Maine coast road trip itinerary breaks the drive into a relaxed nine days, with short driving legs, clear overnight bases, and a sense of where to linger and where to keep moving.
The trip runs one way from Portland to Bar Harbor, broadly following Route 1 northeast along the coast. The actual driving is easy, with most legs under an hour, but the coast rewards an unhurried pace. Plan to fly into Portland and out of Bangor near Acadia, or build in a day to drive back.
This is a scenic, experience-led drive rather than a hard adventure. It suits travellers who like small harbour towns, seafood, short coastal walks and big Atlantic views, and who want one genuine national park at the finish. It works as gentle sightseeing, or as an active week if you add the hikes at Camden Hills and Acadia.
Nine days is generous and comfortable, with two nights each in Portland, Camden and Bar Harbor. If you have less time, cut it to seven by dropping a night in Portland and skipping the Boothbay detour. Acadia deserves two full days whatever you trim elsewhere.

Start in Maine's harbour city. Wander the cobbled Old Port for seafood and breweries, then drive out to Portland Head Light at Cape Elizabeth, the state's most photographed lighthouse. A Casco Bay mailboat cruise is an easy half day on the water.
A short hop north brings you to Freeport, home of the 24-hour L.L. Bean flagship. Balance the outlet shopping with a walk at Wolfe's Neck Woods State Park, where shore trails run through pines above Casco Bay.

Detour 12 miles off Route 1 to Boothbay Harbor, a working harbour of weathered shops and schooner docks. Cross the long wooden footbridge, visit the Coastal Maine Botanical Gardens, or drive the scenic Ocean Point loop.

The Midcoast's prettiest harbour is the trip's best base. Drive or hike Mount Battie in Camden Hills State Park for the classic view over Penobscot Bay, then day-trip to Rockland for the Farnsworth Art Museum and the mile-long walk out to the Breakwater Lighthouse.
White chalk cliffs, a Norman conquest battlefield, cobblestoned medieval streets and a seaside city that refuses to be ordinary: this East Sussex road trip itinerary covers it all in seven days.
Cross the Penobscot River at Bucksport, the gateway to Downeast Maine. Ride the lift up the Penobscot Narrows Bridge Observatory, the tallest public bridge observatory in the world, and tour the granite ramparts of Fort Knox below.

Finish on Mount Desert Island beside Acadia National Park. Drive the 27-mile Park Loop Road past Sand Beach and Otter Cliff, climb Cadillac Mountain for sunrise, walk the easy shore loop at Jordan Pond with popovers at the pond house, and end with sunset at Bass Harbor Head Light.
Front-load the Midcoast, which has the most towns to wander, and protect your two full days in Acadia. Two-night bases in Portland, Camden and Bar Harbor stop the trip feeling like a string of one-night stays.
The sweet spot is September to mid-October. Early September keeps the water warm enough to swim and the seasonal businesses open, with far thinner crowds than July and August. Early October adds Acadia's famous fall foliage. Many coastal restaurants and boat trips wind down by late October, so check seasonal hours if you travel late.
This is a straightforward self-drive route and any car handles it. The one thing to plan ahead is Acadia: a Cadillac Summit Road vehicle reservation is required from mid-May to mid-October, booked on recreation.gov, and the free Island Explorer shuttle is a good way to skip parking stress on Mount Desert Island in peak season.
Route 1 traffic bunches up around Wiscasset and Bar Harbor in summer, so drive the busiest stretches early or late. Tides matter at Thunder Hole and Bar Island in Acadia, so check times before you walk out. Book accommodation in Bar Harbor and Camden months ahead for the autumn foliage weeks.
