The country's oldest lighthouse is just one of the nautical attractions in Portland, and, as well as exploring the waterfront, there are ample opportunities to take a cruise out into Casco Bay and try spotting some wildlife. Whilst the sea makes for a great vantage point from which to admire Portland Head Light, you can also enjoy fine views across town from up on Western Promenade. Down in the Old Port, you can spend a great afternoon sampling the cafes and browsing the shops. If you rent an RV in Portland, or one of the nearby towns, and have a few days to explore this region of Maine, then this historic town is a good place to start.
