Covering more land than any other city in the contiguous United States, Jacksonville wraps around the wide St. Johns River on its way to the Atlantic. The Riverwalk, Jacksonville Zoo and Gardens, and Timucuan Ecological and Historic Preserve offer plenty to explore, along with lively districts like Riverside and San Marco. I-95, I-10 and I-295 provide access across the city. Homes range from downtown condos to historic houses and suburban neighborhoods.
