This is a pro tip, but also a summer tip, take the ferry from Lower Manhattan to Rockaway and spent the day. The beach is great and the area is impossible to gasp that it's 30 min from Manhattan (without traffic) - Eat as many tacos you can, cause it's the best in the state of New York!

Fun shopping for very well-curated vintage. It feels like a series of art galleries that sell clothing and housewares.

My second-favorite outdoor-place in Manhattan. The abandoned 1.6 km rail tracks running above Chelsea down to the Meatpacking district were turned into an above-ground park. Perfectly nice place for sitting in the sun, reading, relaxing, having lunch in some green spot in the city. Nice views at the Hudson River, New Jersey, the Statue of Liberty (little small from there but still visible) and the architecture around Chelsea.

Eero Saarinen’s landmark 1962 TWA Flight Center at JFK Airport restored and reimagined as a first-class hotel.

Housing European Romanesque and Gothic collections, the building itself sits high on a hill offering far reaching views over the Hudson River and Upper Manhattan. A place to bookmark for after the Spring equinox when you can ramble amongst the fragrant herb gardens of Fort Tryon Park and drink in the air of the season.
