Not a beach day?
How about a leisurely walk through the Cape Cod Museum of Art located in Dennis Village on the grounds of the Cape Cod Playhouse Center for the Arts. The museum is celebrating thirty years of preserving and fostering art on Cape Cod. There are seven galleries, a sculpture garden, art classes, library, special events and even a screening room featuring independent films - definitely enough to fill an afternoon.
After the museum, you can stroll over to The Mercantile for a cup of coffee and some local color then maybe finish off with a drive through the neighborhoods enjoying the beautiful homes along the way and then land at Bass River Park overlooking the beautiful Bass River.
