Stretching from Jacksonville's southern edge to miles of Atlantic coastline, St. Johns County blends centuries of history with coastal living. St. Augustine's Castillo de San Marcos and brick-lined historic streets anchor the south, while Ponte Vedra Beach, Nocatee and World Golf Village offer golf, trails and beach access. Anastasia State Park preserves dunes and marsh. I-95, US 1 and A1A connect communities. Housing includes historic homes, beach condos and master-planned neighborhoods.
