Planning your trip? Here are the highlights most worth your time in Miami.
Miami's iconic beach strip — Art Deco hotels, outdoor dining, and some of the best people-watching in America. The beach itself is clean, well-maintained, and free. Walk south to the quieter sections beyond 5th Street for more space.
From industrial warehouse district to globally recognized street art destination in under 15 years — Wynwood Walls is the centerpiece but the entire neighborhood is covered in curated murals. Excellent restaurants and cocktail bars throughout.
Miami's oldest neighborhood — a bohemian enclave of banyan-shaded streets, waterfront marinas, excellent farmers markets (Saturday mornings), and the Vizcaya Museum (a Gilded Age Italianate estate on Biscayne Bay).
Miami's downtown skyline viewed from Bayfront Park at sunset is one of the city's most underrated views. The American Airlines Arena and Bayside Marketplace are adjacent. Brickell Ave has become Miami's upscale dining and drinking hub.
The Overseas Highway south from Miami leads through 42 bridges connecting the Keys — Key Largo (1 hour) for snorkeling, Islamorada (1.5 hours) for sport fishing, Marathon (2 hours) for Dolphin Research Center, or all the way to Key West (3.5 hours).
Miami's luxury design and fashion precinct — LVMH flagship stores alongside independent galleries, exceptional restaurant spots, and the Institute of Contemporary Art (ICA) with free admission.
Local insider tip
Cubans in Miami don't go to Versailles for daily dining — they go to La Rosa Bakery or any of the dozens of pastelería bakeries for a croqueta, a media noche, and an espresso for under $5. The cafeteria windows on Calle Ocho, open from 6am, are the authentic morning ritual.
