How we would fit it into your day

Plan from downtown Rockland and keep each day focused on one destination. Thomaston, South Thomaston, Cushing and St. George are separate towns; Port Clyde and Tenants Harbor are villages in St. George. Check museum closures and actual boat departures. The breakwater has uneven granite and no railings; lighthouse grounds access does not include a tower tour. No Monhegan ferry trip is automatically included.

Before you go

No vehicles on the causeway, camping or fires. Use designated preserve parking, not inn guest spaces or road shoulders. Keep pets controlled and stay on trails; quarries and old wells create hazards. No swimming is included in this plan.
