Governors Island

New York, New York

It’s been more than a decade since this former Coast Guard facility—a 172-acre hunk of land off the coast of Manhattan—re-opened as a public park. But it continues to evolve. In 2016 it welcomed the Hills, a tiered, man-made mound designed to offer stunning vistas (and also withstand the effects of climate change), and this summer, it launched its first “glamping” experience, allowing guests to stay over­night in luxe tents. —Wilder Davies
