Generally speaking, walking tours are a great idea—they allow you to get to know a place intimately; to experience it as its locals do daily, and to exercise while you learn on vacation. Miami tours are a wonderful way to get to know the city during a vacation to this part of Florida, and a walking tour is a particularly interesting and unique way to do so.
Miami is particularly well-suited to walking tours. A Miami walking tour may focus on one of many areas of the city, or it might focus on sites that are all tied together by a theme, such as in an Art Deco walking tour. Furthermore, they’re all blessed with perfect conditions, as Miami is an agreeably warm and sunny place, especially during the summer months; it’s all very well to extol the virtues of walking, but few people will be willing to hike around a city in pouring rain.
If you want to do a walking tour arranged by a company, an Art Deco Walking Tour is an excellent option. These walking tours in Miami are arranged by the Miami Design Preservation League, which aims to raise international awareness concerning the level of excellent architecture in the city. For a small fee, you get a 90-minute guided walk around Miami’s Art Deco Historic District, with informative anecdotes provided on the various Art Deco, Mediterranean Revival, and Miami Modern building styles to be seen.
If you'd rather take a self-guided Miami walking tour, the Miami Beach waterfront is probably the place to go. There are many things to do here, though it's particularly recommended that tourists on walking tours in Miami visit the Bayside Marketplace, gaze at the massive yachts and general high-life of the port, and take in a concert at the AT&T Amphitheatre, though the last option likely requires a bit of advance preparation.
