The infinity pool at Marina Bay Sands is the largest of its kind in the entire world—giving tourists a chance to take in the city from every point of view.

This pool exhibits a shock of color against the sedated, minimalistic design of The Library resort in Koh Samui, Thailand, right outside of Chaweng Beach.

Everything in Vegas is extravagant, including this award-winning pool at the Golden Nugget. Here, hotel guests can swim with the sharks—separated by a thin layer of glass, that is.

If Jaws isn't really your thing, relax at the H20 bar or hang by the rejuvenating waterfalls.
