Celebrating 50 years since its opening, Bal Harbour Shops is the fourth Florida mall to make the list. The open-air center brings the state's tropical environment to life with a resort-like aura. Fish ponds and palm trees are weaved throughout the family-owned center, which is awaiting approval on an expansion plan.
