Portland is a city that rests on the coastline of Maine, which has a rich maritime history. You can find some natural attractions within the confines of the city, but if you head only a small way out, you can experience nature in a way you never thought possible. Head to Casco Bay, which is a hot spot for fishing and sailing, and where you can also find views that stretch into the horizon, or explore the hiking trails of Eastern Promenade. In the warmer months, relax on the shores of Crescent Beach State Park to watch the sun go down, and catch more scenic views as you hike around Two Lights State Park. Most of all, make sure to stay in a unique rental to make your trip stand out from the rest.
