I recently took my first trip to Cape Cod with my family, and it was a great trip. The area definitely has a lot of character, and there are some beautiful beaches throughout the Cape. For an East Coast destination there is a nice middle-America type of vibe. There are plenty of places to eat, and most are family owned type of businesses rather than the usual chains. Provincetown was a cool town to visit, although the nearly naked young men advertising for "Nude Boys Singing," wasn't quite family friendly. However, the whale watching trip from there was well worth it. Cape Cod National Seashore has several areas to visit, and the beaches there are absolutely beautiful. There are also plenty of bike paths throughout the area, which I think is a great activity for families.
