Delaware Topography and Tourist Attractions

Delaware is named after the Delaware River and Bay, which themselves were named after Sir Thomas West, the Baron De La Warr.  Delaware is the second smallest state (after Rhode Island).  Most of the state lies on the DelMarVa peninsula, a coastal plain lying between Chesapeake Bay to the west and the Atlantic Ocean to the east.  Tidal marshes teeming with wildlife along Delaware Bay gradually yield to sandy beaches along the southern shoreline.  Rehoboth Beach and Bethany Beach are popular summer vacation destinations.  For Delaware travel and tourism information, visit the official Delaware tourism site and Delaware Atlas
