After landing at Portland International Jetport, allow roughly 10–15 minutes by car or rideshare to Bug Light Park in South Portland. A rental car is easiest for this route; parking at the park is generally straightforward, though arriving earlier gives you the best chance at a convenient space. Start with an easy waterfront stroll to Portland Breakwater Light (Bug Light), a petite, ornate lighthouse with excellent views across Portland Harbor toward the working waterfront. Give yourself about an hour here, and bring a light layer—this shoreline is often breezier than the airport or downtown.
Drive a few minutes to Spring Point Ledge Lighthouse at Southern Maine Community College. From campus, follow the paved breakwater out into the harbor; the walk is scenic but exposed, with uneven stones near the lighthouse, so wear shoes with good grip. Plan on about 1½ hours to enjoy the lighthouse, Fort Preble surroundings, and views back toward South Portland and Portland’s skyline. Campus and waterfront access can occasionally be affected by events or maintenance, so check local signs when you arrive; the breakwater itself is best treated as a daytime visit.
Continue to Willard Beach, where a relaxed shoreline walk offers a quieter, neighborhood-scale view of Casco Bay. Spend about an hour wandering the sand and nearby streets rather than trying to pack in another major attraction. Then head to Willard Square for lunch or an early dinner at David’s Opus 10. Expect creative American cooking and roughly US$25–45 per person before drinks and gratuity; reservations are sensible, especially on a Friday, and hours can vary seasonally, so confirm the day’s service before setting out. This is a good place to let the day finish gradually—after the exposed lighthouse walks, the small local dining scene around Willard Square feels pleasantly unhurried.
From South Portland, leave around 8:00–8:30 a.m. for Portland’s Old Port waterfront—roughly 10–20 minutes by car or rideshare via I-295 N/US-1. Allow extra time to park in a paid garage or lot rather than circling the narrow waterfront streets; the Casco Bay Lines area is the useful landmark for harbor departures. Board a morning Portland Harbor lighthouse cruise for the best practical views of Ram Island Ledge Lighthouse, usually a 2–3-hour trip costing approximately $35–60, depending on the operator and sailing. Bring a windproof layer even in September, and confirm the exact departure time the night before, since cruises are weather- and availability-dependent.
After returning, drive about 15–25 minutes south to Portland Head Light in Fort Williams Park. The lighthouse grounds are open year-round from sunrise to sunset; parking is typically paid seasonally, with rates often around $5–10, and the lighthouse tower itself is not generally open for climbing. Spend about 1½ hours walking the cliff paths, checking the museum when open, and taking in the view toward Ram Island Ledge and the open Atlantic. Leave plenty of time for Fort Williams Park itself: the former military site has easy coastal trails, old fortifications, and broad harbor overlooks, so a relaxed loop is more rewarding than trying to see every path. The terrain is uneven near the cliffs, and swimming is not permitted along the rocky shoreline.
Return to Portland—about 15–20 minutes by car—and settle into Eventide Oyster Co. in the Old Port for dinner. Expect roughly $30–60 per person before drinks; oysters and Maine seafood are the draw, but the restaurant can have a wait, particularly on a Saturday evening, so join the list as soon as you arrive. Afterward, take a short wander along Commercial Street and the nearby cobbled lanes before heading back; this is a good day to keep the evening unhurried after the boat trip and coastal walking.
Start around 8:30–9:00 a.m. with a drive or rideshare from Portland toward Two Lights State Park in Cape Elizabeth, allowing about 15–25 minutes via ME-77. A car is particularly useful today because the coastal sights are spread out and rideshare pickup can be slow. At Two Lights State Park, give yourself roughly two hours to follow the rocky shoreline, watch for seabirds, and enjoy the open Atlantic views. The park has paved areas as well as uneven coastal paths, so sturdy shoes are worthwhile; bring a light layer, since it can feel breezy even on a sunny September morning. Parking is paid or seasonal, so check the posted kiosk when you arrive.
Late morning, continue to the public viewpoints around Cape Elizabeth Light, about a five-minute drive from the state park. You cannot generally tour the lighthouse interior, but the surrounding grounds and ocean-facing viewpoints make this one of the most photogenic stops on the route. Allow about 45 minutes, and keep clear of private property and any restricted areas around the light station.
Drive roughly 10 minutes south to Kettle Cove State Park for a quieter change of pace. Spend about an hour walking the beach and the nearby coastal trail; low tide is especially pleasant, though the shoreline can be rocky and wet. There is usually a day-use parking fee, and facilities are seasonal, so carry water and do not count on restrooms being open late in the year. Afterward, head back toward Willard Square—about 15 minutes by car—to Scratch Baking Co. for pastries, excellent bread, or a light lunch. It is popular with locals, and the selection can thin out later in the day, so arriving mid-afternoon is better than waiting until closing; budget approximately $10–20 per person.
Finish at High Roller Lobster Co. on the South Portland waterfront, around a 10–15-minute drive from Willard Square. Settle in for a casual lobster roll or another seafood meal—roughly $20–40 per person—and, if the weather cooperates, linger outside for the harbor atmosphere. Check same-day hours before setting out, as seasonal schedules can change in September. Expect the full day to feel relaxed rather than rushed, with the best light along the coast in the morning and an easy waterfront dinner to close it out.
