Hilton Head, in South Carolina’s “Lowcountry” (low-lying coastal region) is planned out beautifully to maintain the native state of the area with its abundant natural beauty including tree lined streets and pathways and organic beaches!
The island is bathed in lush vegetation including enormous Cypress trees and magnificent Magnolia trees. Salt marshes are found throughout the island as well as freshwater marshes, wetland forests and tidal zones preserving the area for the plentiful wildlife. (TBH, it was not at all what I expected for a coastal area. There are no condos and high-rises lining the beach with bumper-to-bumper traffic. Lots of green vegetation and unspoiled landscapes far and wide.)
