Plimoth Patuxet (formerly the Plimoth Plantation) is an indoor/outdoor museum commemorating the history of the area. If you have never been there, it is quintessentially Plymouth and a fun and interactive walk through both Pilgrim and Wampanoag lifestyle.
The almighty Plymouth Rock in the heart of America's Hometown. The biggest tourist trap, and the biggest let down, the Plymouth Rock is said to be the first rock touched by the Pilgrims at Plymouth Landing. It is unfortunately not the original rock and not very big. But, maybe you still want to see it just to say that you did.
If you arrive on Friday (or earlier!), check out Plymouth's Main Street, Court Street, and Water Street for food and nightlife. If you're looking for small bites, crafty cocktails, and chill vibes - we recommend Honey Baby.
