One of my favorite places in New England! To really experience "the Cape", you need to head all the way out past the "elbow" and north from there up to the Outer Cape. If you want to spend time at a "real" beach, make sure you get out to the Cape Cod National Seashore.
The Cape Cod bike trail is a great way to spend the day. In fact, biking is excellent on the cape and on the nearby islands of Nantucket and Martha's Vineyard. The kettle ponds that are everywhere are some of my favorite warmwater swimming holes in New England. A first class day for me combines biking with numerous stops and swims at the kettle ponds, the seashore, and any ice cream stand (and sometimes seafood too!).
It might be tough finding a place to stay on the most popular weekends, but in addition to the excellent campgrounds, there are some great hostels. I like to stay at the awesome Truro Hostel, the Mid-Cape Hostel, and the Nantucket Sea Star and Martha's Vineyard hostels. Nickerson State Park is one of the best campgrounds, but make reservations early,
Getting to the islands is tough sometimes if you try to take your vehicle, but the Steamship Authority and other ferry systems make it all possible.
