Miami is a young city that grew in a hurry and then had to rebuild itself more than once. In the 1910s a promoter named Carl Fisher turned a mangrove jungle on a barrier island into Miami Beach. In 1926 a hurricane ended the land boom, and the small stucco hotels built in the Depression years afterward are the Art Deco South Beach you see today. Then came the Cuban exiles of the 1960s, Haitians, Puerto Ricans and Latin Americans from half a continent, and the city that dances to salsa, eats croquetas for breakfast and speaks Spanish in the supermarket is mostly their work. Miami is not a European city by the sea, and it is not quite the rest of Florida either.
It is a city of separate worlds joined by traffic, which is why five days is the right length. You need one day for South Beach and its beach, one for Little Havana, Wynwood and Little Haiti, one for Vizcaya, Coconut Grove and Coral Gables, and one for Key Biscayne, where the sand is quieter. That leaves one day to leave the city, either for the Everglades or, more ambitiously, for the Florida Keys. We pick the Everglades for the day trip and say plainly why the Keys are better as an overnight. The city is hot and wet from May to October and warm and dry from November to April, and hurricane season runs from 1 June to 30 November, so this plan assumes you are going in the dry months.
Each day stays in one part of town. Day one is South Beach, day two Little Havana, Wynwood and Little Haiti, day three Coconut Grove and Coral Gables, day four Key Biscayne and the downtown skyline, and day five a day trip to Shark Valley in Everglades National Park. Start on a Thursday: Vizcaya is closed on Tuesdays, the Pérez Art Museum on Tuesdays and Wednesdays, the Venetian Pool on Mondays and the Institute of Contemporary Art on Mondays and Tuesdays, and a Thursday start puts Vizcaya and the pool on a Saturday, Key Biscayne on a Sunday and the Everglades on a quiet Monday.
