Southern Delaware is noted for wildlife and marine habitat, beaches, fields, forest, wetlands, rivers and lakes. The coastal side is deeply indented by Rehoboth Bay and Indian River Bay. Wide beaches grace Rehoboth Beach. This coastline to the mouth of Delaware Bay is 28 miles long. The interior is given over to many farms contributing to the state's number one industry, agriculture. Also inland at Millsboro is the Nanticoke Indian Pow Wow, a festival of Delaware's original inhabitants. The Nanticoke Indian Museum, also in Millsboro, is in a former school converted into a house of native cultural objects, including spear points and local pottery.

Visitors will encounter religious objects, muskets, cannons, gold and silver objects. Also at the college is a unique arboreal collection, Trees of the States.
