Tampa's waterfront district or Riverwalk has everything you could want for a relaxed morning or evening, with restaurants, shops, parks, an aquarium, and some of the museums on this list. It's a pedestrian-friendly 2.4-mile stretch, and you can switch to the water when you tire of having the ground under your feet. E-boats and water bikes are readily available, or you can kayak or stand-up paddleboard.
