8:00 — Sunrise walk on South Beach. The sand is widest and quietest now, and the lifeguard towers glow in first light. Swim if the season allows — winter water is typically warmer here than anywhere else in the continental US.
9:30 — Breakfast on Ocean Drive or Española Way, then walk the Art Deco Historic District: hundreds of pastel 1930s buildings, the largest concentration of Art Deco architecture in the world. The Art Deco Welcome Center runs classic guided walks most mornings.
12:30 — Cross the causeway to Little Havana. Lunch at Versailles, the famous self-declared most famous Cuban restaurant in the world: ropa vieja, plantains, and a cafecito at the walk-up ventanita. Then stroll Calle Ocho — cigar rollers, fruit stands, and dominoes clacking at Máximo Gómez Park.
15:00 — Wynwood. The Wynwood Walls turned this warehouse district into an open-air museum of large-scale murals, now surrounded by galleries, breweries, and some of the city's best coffee. Give it two hours and wander beyond the official walls — the whole neighborhood is painted.
18:30 — Head to Brickell or the downtown bayfront for golden hour: rooftop bars and the skyline lighting up over Biscayne Bay.
21:00 — Dinner and drinks: Brickell for sceney rooftops, or back to Miami Beach where the deco neon buzzes to life along Ocean Drive.
