What's the must-see thing in Miami?

Vizcaya is Miami's one building that makes you stop and recalibrate. James Deering, a vice president of International Harvester, spent $22 million in 1914 dollars importing Venetian columns, Spanish ceiling panels, and Roman marble sarcophagi to furnish 34 rooms overlooking Biscayne Bay. The corridors carry the smell of 500-year-old limestone and salt water drifting in off the bay. You walk through rooms where the temperature drops 5 degrees from the thick coral-rock walls, then out onto a stone barge that juts into the water where pelicans dry their wings 3 metres from your feet. The formal gardens run 10 acres of clipped hedges and fountains modeled on Italian villas near Lake Como. Go before 11am. By noon the humidity sits around 80% and the shadeless garden paths feel punishing. Morning light hits the east-facing loggia at a low angle that makes the 16th-century tapestries glow a deep copper.

Vizcaya sits at 3251 South Miami Avenue in Coconut Grove, about 15 minutes by car from South Beach or 25 minutes on the Metrorail to Vizcaya station. Admission runs $25 for adults, $10 for children 6 to 12, free under 6. The estate closes Tuesdays. Worth noting, the audio guide comes included in the ticket price and takes about 90 minutes if you follow every room. Most visitors spend 2 to 3 hours total with the gardens. If you're visiting in June, the 81% humidity and 25°C mornings currently typical mean lightweight clothing and water are non-negotiable. The on-site cafe sells Cuban coffee for $3.50 that's better than most of what you'll find on Ocean Drive.

Your second priority is Pérez Art Museum Miami, called PAMM locally, at 1103 Biscayne Boulevard in Museum Park. The building matters as much as the collection. Herzog and de Meuron designed the cantilevered concrete structure that opened in 2013, and the hanging gardens at the entrance drip with tropical plants that make the air smell like wet earth and frangipani after rain. Admission is $16, free on second Saturdays. The waterfront terrace behind the museum faces directly across to Fisher Island, and the breeze off the bay drops the felt temperature by 3 or 4 degrees compared to the street-level sidewalk on Biscayne Boulevard. Third pick is the Holocaust Memorial at 1933 Meridian Avenue in Miami Beach. A 13-metre bronze arm rises from a reflecting pool, covered in over 100 life-sized human figures. It tends to stop visitors mid-sentence. Free entry, 30 to 45 minutes.

What you might expect me to recommend instead. South Beach's Ocean Drive strip between 5th and 15th streets appears on every Miami postcard, and it is worth walking once. The Art Deco facades look best from the west sidewalk at 7:30am when the light turns pink-gold and the tourist bars still have their shutters down. Don't eat there. Restaurants along that strip charge $28 for a mediocre club sandwich, and the hosts physically grab your arm as you pass. To be fair, the architecture is real. Twelve blocks of 1930s streamline moderne hotels, many designed by Lawrence Murray Dixon and Henry Hohauser, deserve your attention. But as a first-timer priority competing against Vizcaya or PAMM, Ocean Drive is the weaker pick because the setting overwhelms the substance after 20 minutes of walking. The 1116 Ocean Drive building alone might change your mind, though.
