The 75-foot indoor pool at the Four Seasons in the Financial District is heated and surrounded by cushy loungers—a perfect retreat for any season, basically. Alas, it's only available to hotel guests, or as an amenity for those who live in the fancy condos above at 30 Park Place. (Make friends with one of those folks, is what we're saying.)

The pool on the roof of the James Hotel in Soho may be small, but it is on the roof and, more importantly, it's open to the public after 3 p.m. on the summer weekends, as is the rooftop bar.

SIXTY Lower East Side, formerly Thompson LES, is, as far as we know, New York's only hotel with an Andy Warhol print on the bottom of its rooftop pool. It’s open to hotel guests and those with day passes—you can snag one of those for $65 on weekdays, or $95 on weekends.

A member's club with hotel rooms, the Soho House has a rooftop pool that is heated, open year-round, and among the most exclusive in the city. Access is only allowed to hotel guests or members (memberships start at $1,080/year, depending on your age and the level of access you're after). There is an adjacent roof restaurant.

The 45-foot rooftop pool in the Gansevoort Meatpacking NYC is not only heated but features underwater lights and music as well. (It’s available for hotel guests only.) Things aren't so bad above the water either, with an adjacent bar and lounge.

The 4,800-square-foot Beach at the Dream Downtown Hotel features white sand imported from the Hamptons, a smattering of cabanas, and a glass-bottomed pool, through which you can apparently see the hotel lobby. Pool passes are available to non-hotel guests Monday through Friday from $65/day.

The former Le Parker Meridien is now Parker New York, and fortunately, its pool with sweeping Central Park views remains. But you’ll pay for the privilege: A day pass to the pool and fitness center is $150.

The Park Hyatt New York, which occupies the lower floors of One57, is home to a stunning pool that—surprise, surprise—is open only to hotel guests and residents of the condos above. It has underwater speakers that pipe in classical music (a nod to Carnegie Hall, located just down the block), so you can feel very cultured and fancy all at once.

Looking to really treat yourself? The Mandarin Oriental Hotel offers a 75-foot, three-lane lap pool on the 35th floor with Hudson River views as part of its very impressive 14,500-square-foot spa.

Long Island City’s Ravel Hotel recently turned its outdoor pool into the Profundo Day Club, which offers day passes for as little as $25. Take note, though: There’s a strict dress code that visitors must adhere to.

The brand new TWA Hotel has its own rooftop infinity pool and lounge, with the bar portion operated by the Gerber Group. The 63-foot-long pool, open to hotel guests, will be open year-round—in the winter, it can get heated up to 100 degrees.

Williamsburg's zany William Vale Hotel is home to one of the city's largest hotel pools, measuring 60 feet long and located on its third-floor amenity deck. The hotel is also home to Westlight, one of the best new hotel bars with a view. The pool offers day passes, but the prices are steep: They start at $99/day, and go up from there for larger parties. There’s also a membership option if you love to swim.

One of Williamsburg’s newest hotels—it opened last year—has a publicly accessible pool on its rooftop, with day passes starting at $65.

Brooklyn’s eco-friendly hotel also has a lovely hotel pool available to guests. The best thing about it is the view, a postcard-worthy vista of the Lower Manhattan skyline. While the public will have a hard time getting in for a dip, the hotel’s rooftop bar and lounge is open to the public, though reservations are recommended.
