Quick self-guided walk around the Capitol grounds and nearby historic Monument Avenue; the Capitol is generally open to visitors daytime (confirm tour times).
Visit the birthplace of the United States government; Independence Hall has timed tours and the Liberty Bell Center is open during daytime hours (check National Park Service schedules for ticket times).
Short interstate drive (roughly 1.5–2.5 hours to Manhattan depending on traffic); aim for mid-afternoon arrival to avoid peak rush-hour toll congestion.
Visit the RISD Museum (typically open 10:00–5:00; check current hours) or enjoy the Providence riverwalk and historic downtown — both provide a relaxing afternoon option.
Dine at the acclaimed Italian restaurant Al Forno on Federal Hill — known for grilled pizzas and regional Italian dishes; reservations strongly suggested.
Take a quick park walk or explore Federal Hill’s cafes and bakeries; the zoo opens later in the morning so the park is a good early activity (park open daylight hours).
Final driving leg along scenic coastal stretches (roughly 1.5–2 hours from Portsmouth to Portland depending on traffic); arrive mid-afternoon to explore the Old Port.
Drive (about 15–25 minutes) to this iconic Maine lighthouse — the headland and park are generally open daylight hours and offer dramatic coastal views; sunset timing in late September is around 6:45–7:00pm, so plan accordingly.
Finish the road trip with fresh New England seafood and a famed lobster roll; dinner service in Portland is lively — reservations or an early seating recommended.
