St Marys Highland is a subdivision in Hilliard, a small town in western Nassau County along US 301 and US 1, close to the St. Marys River and the Georgia state line, northwest of Jacksonville. This is timber and farm country, where residential streets give way quickly to pine woods, pastures and the river swamps along the state border. Housing in the Hilliard area is generally single-family and low-density, with homes on individual lots and room between neighbors, in a pattern far removed from Jacksonville's suburbs. Public schools are part of Nassau County School District, and Callahan and Folkston, Georgia, are the nearest larger stops for shopping and services. Hilliard keeps its own small commercial center along the highway corridor. Browse current St Marys Highland homes for sale below.
