At Assateague Island, near Girdletree, the campground sits right behind the dunes, and the wild horses don't care that it's a campground. They wander between the sites, graze the marsh grass and walk the beach at sunrise. Keep your food locked up, because they've learned what a cooler is.
Inland, Catoctin Mountain Park near Thurmont has old cabin camps from the 1930s in the hardwood forest. Pocomoke River State Park has campsites by a cypress swamp, and the Patuxent River near Dunkirk has a canoe camp you paddle to. Ocean City has the big RV campgrounds if you want the boardwalk.
