Rooftop and hotel pools open to the public in NYC

La Piscine at Hôtel Americano

• Price band: 3/4

The pool area atop this ten-floor Chelsea boutique hotel opens to the public at 6pm (not for swimming, though toe dips are welcome); but the adjacent bar and grill welcomes patrons from noon and boasts expansive views of Manhattan and the Hudson River. Warm-weather locales inspire the menu: Dishes such as taramasalata with pita ($7) and grilled octopus salad ($18) skew Mediterranean, while the drink list includes hibiscus margaritas served by the glass ($16) or pitcher ($82). • (212-525-0000, hotel-americano.com). Pool: Daily 6pm–midnight. Bar: Daily noon–midnight.

The Pool at King & Grove Williamsburg

This 40-by-20-foot, four-foot-deep saltwater swimming hole may not perch on a roof, but the ground-floor deck makes up for lack of altitude with the chance to do laps. The spacious terrace seats 150 and offers poolside service, with cocktails like the Daytripper (Aperol, strawberry-infused bianco vermouth, soda; $9) and bites such as a crispy soft-shell-crab panino ($14). • (718-218-7500, kingandgrove.com). Daily 11am–9pm. Mon–Thu $30, Fri–Sun $45. Reservations required.

Bar d’Eau at Trump SoHo

• Price band: 4/4

An arching waterfall spills into the Trump SoHo’s mosaic-tiled pool, set on an L-shaped seventh-floor patio and surrounded by deck chairs and lounge seating. While swimming is forbidden in the evening, a bocce court provides a dry diversion, bolstered by haute bar snacks ($10–$22) and cocktails ($15–$20). • (212-842-5500, trumphotelcollection.com/soho). Mon–Thu, Sun 6–10pm; Fri, Sat 6–11pm.

The Beach at Dream Downtown

• Price band: 3/4

The second-floor terrace of this mod Meatpacking District hotel channels the French Riviera with crisp navy-and-white chaises and umbrellas; a glass-bottomed pool, visible from the lobby downstairs; and even sand—shipped in from Montauk—in a separate beach area (keeping the water grit-free). In the evening, swimming’s off-limits, but those in need of a daytime plunge can skirt the guests-only rule by booking one of two cabanas, which seat up to ten. • (212-229-2336, marblelane.com). Daily 5:30–10:30pm. Cabana rental: day 10am–6pm, evening 6–11pm, all-day 10am–11pm.
