Las Vegas has its fair share of stellar hotel pools, but none are quite as singular as the one at the Golden Nugget. This pool in downtown Las Vegas features a 200,000 gallon shark tank, allowing guests to swim up-close to several species of sharks and tropical fish. A three-storey water slide shoots through the shark tank before splashing into the main deck pool.

Carved around the natural contours of a 80-foot stone bluff and set into a sunken courtyard, the pool at Amangiri in Canyon Point, Utah seems to blend into its surroundings. And because the modernist sandstone hideaway is so remote, nighttime swimmers can stare up at a sky full of stars. King size day beds, sun loungers, a fire pit and a adjacent hot tub make this a pool to enjoy year round.

During the winters, the pool is kept at 80 degrees, perfect for an aprés-ski dip.
