Bug Light Park, the eastern terminus of the Greenbelt Walkway, offers expansive views of Portland Harbor and the skyline of Maine’s largest city. The nearly 9 acre park was the site of major shipbuilding activity during WWII. An estimated 30,000 people were employed here from 1941-1945 building liberty ships for the New England Shipbuilding Corp. and the South Portland Shipbuilding Corp. Although far less bustling today, Bug Light Park is a popular destination for picnicking and boating. A busy boat launching area (seasonal fees required) and a liberty ship memorial are at opposite ends of the park. In between is a paved walkway along the shore and out to Bug Light itself.
