Destin to Biloxi Road Trip: Gulf Coast Gems

Along US-98, the 160-mile drive from Destin, Florida to Biloxi, Mississippi hugs the Gulf of Mexico for nearly its entire length. A unique geological feature here are the rare coastal dune lakes, like those at Grayton Beach State Park, where fresh water meets the sea through ephemeral outlets.
