Janes Island State Park (Eastern Shore, Md.): For sunset vistas over the Chesapeake Bay, the campsites at this park north of Crisfield can't be beat. Many sites sit on the water's edge, offering unobstructed views and access to the canoe trail. If you prefer less-primitive accommodations, there are a few waterside cabins as well.
New Germany State Park (Garrett County, Md.): It's small, with only 37 well-spaced sites, but they are clean, well kept, and offer easy access to hiking trails, fishing spots in the park's lake, and the facilities of several other Western Maryland state parks and forests. The 11 cabins are great options for winter cross-country skiing trips.
Potomac-Garrett State Forest (Garrett County, Md.): For primitive camping in the mountains, head to this state forest in Western Maryland. Nearly all the campsites are within walking distance of one of the forest's mountain streams, and they're so spread out, you'll never know if you have neighbors.
Cape Henlopen State Park (near Lewes, Del.): Summer beach camping is always a tenuous venture, with the heat, the bugs, and the sand. But the facilities at Cape Henlopen make for the best beach experience: There are 159 wooded sites, several with full hookups and all with access to bathhouses and running water. Within the park, you'll find several miles of hiking and biking trails, guarded beaches, and great fishing.
