It doesn't get much higher than the Sky Park Infinity Pool at Singapore's Marina Bay Sands. You'll need a hotel key card to access this 57th-floor pool -- the highest in the world, but it just may be worth the cost for the insane views over Marina Bay and Singapore's financial district.
Perched in a spot overlooking a valley in the Swiss Alps, the heated outdoor infinity pool at the Cambrian Hotel in Switzerland is worth the trip to Adelboden just for the views of the surrounding snow-capped mountains. Bubbling massage beds within the pool help you relax and take it all in.
Located 115 feet above sea level, the rooftop pool at the Hilton Molino Stucky Venice allows for panoramic views over the canal-filled city below.

The cantilevered rooftop pool at the Joule Dallas is hair-raising, and not from cold water! The end of the swimming pool dangles off the edge of the building, and a glass allows you to look down on the city below (and lets passersby peek up at you).
If you've seen the 007 flick Skyfall, you'll be familiar with the Four Seasons' knack for infinity pools (the one pictured in the film was in London). They've really outdone themselves at the Four Season Shanghai Pudong with a jade-tiled infinity edge pool that looks out over Shanghai's ultramodern skyline. It's also indoors, so you can enjoy the views rain or shine.
The Thompson Hotel's infinity pool overlooks the famous Toronto skyline and is considered one of the best hotel rooftop pools in the world. In the evenings, the Rooftop Lounge transforms into an upscale bar, complete with a menu of interesting cocktails and finger foods.
If you fancy looking down on the beautiful bodies of Ipanema Beach, you can do so quite literally from the pool at Hotel Fasano Rio de Janeiro. If you get lucky, you may even spot a celebrity or two basking in the sun of this super-chic rooftop oasis.
The Wet Deck sits on the 76th floor of the W Hong Kong nearly 700 feet above Victoria Harbour. Spend your days cooling off in the heated pool, or if it gets chilly at night, watch the iconic Hong Kong skyline light up from an ourdoor Jacuzzi overlooking the city.
Any time of year, guests of the Soho House in New York City are invited to the heated rooftop pool for a swim with views of West Village and the Hudson River. The hotel designates specific children's hours, so you can bet on peace and quiet during the adult-only periods.
