St. Johns County offers a captivating blend of historic charm, pristine beaches, and vibrant communities. Encompassing around 600 square miles, the county boasts a rich history dating back to the 16th century, evident in its Spanish moss-draped oaks and preserved landmarks. Beyond its historical significance, St. Johns County beckons visitors with its stunning Atlantic coastline, featuring sugary white sands and crystal-clear waters ideal for swimming, sunbathing, and water sports. Today, St. Johns County is a thriving community with a population of over 306,000. The county seat is St. Augustine, the nation's oldest permanently occupied European-established settlement, but the unincorporated community of St. Johns actually has a larger population. Ponte Vedra Beach is another popular area, known for its world-class golf courses and resorts.
