Jacksonville is the largest city in the United States, geographically speaking. Its 840 square miles encompass Atlantic beaches, corporate headquarters inside city high-rises, quaint neighborhoods and Florida's longest river, the St. Johns. Just north of Jacksonville, either by interstate or coastal highway with a ferry crossing, lies Amelia Island. This beautiful resort town is Florida's northern-most point before crossing into Georgia. Travelers have come here for generations to relax at luxury properties, play golf by the sea or go horseback riding on natural beaches. Needless to say, there is plenty to do here, from outdoor activities on some 1,000 miles of waterways to enjoying the bustling nightlife, shopping, arts scene and foodie culture of big-city Jacksonville.
