Cape Cod National Sea Shore Guided Tours
We have John F. Kennedy to thank for his move to protect the Cape Cod National Seashore, which stretches 40 miles from Chatham to Provincetown. Besides sunning on one of its many beaches, a top thing to do is to take a guided tour with an expert. Rangers lead biking trips, snorkeling excursions, and lighthouse tours. You can even get a behind-the-scenes peek at an old bomb shelter.
