The Chesapeake Bay is the nation’s largest estuary. It is 200 miles long from its northern headwaters to the Atlantic Ocean. The Bay is home to over 2,700 species of plants and animals. Captain John Smith was one of the first English explorers to map the Bay and in 2006 the nation’s first “all-water” National Historic Trail was created along Captain Smith’s 17thcentury routes. Aptly called the Captain John Smith Chesapeake National Historic Trail. Please see the website of the Chesapeake Bay Program for more information.
