Southwest of Jacksonville along the St. Johns River, Clay County pairs riverfront scenery with established suburbs. Green Cove Springs, the county seat, is known for its historic courthouse and spring-fed Spring Park, while Orange Park, Fleming Island and Middleburg each offer their own pace. Black Creek and Doctors Lake draw boaters and anglers. US 17, I-295 and the First Coast Expressway link the area. Homes range from riverfront lots to master-planned communities.
