Whether you are looking for sun-drenched beaches or outdoor activities in beautiful countryside, New Jersey has plenty to offer. Those who love the great outdoors should head for the Delaware Water Gap National Recreation Area, which runs along the Delaware River for forty miles. Here you can go rock climbing, canoeing, kayaking or fishing, or simply admire the stunning waterfalls. There is a huge range of hiking trails to choose from as well as historic sites to visit. In winter, you can enjoy cross-country skiing near Blue Mountain Lakes, and birdwatchers might be lucky enough to catch sight of bald eagles. If you are looking for a change, visit one of New Jersey's eleven lighthouses that are open to public, such as the one in Cape May. For art and history enthusiasts, New Jersey State Museum in Trenton has historic artefacts and American fine art from the nineteenth century to the present day as well as a Planetarium.
