There are the most memorable hotel pools and even what people consider the "best" hotel pools , but what about the craziest hotel pools? We've seen the scariest (hello, glass bottomed and 24 stories up!) and even the largest , but what about the most insanely beautiful -- think infinity pools with sweeping views -- architectural or interesting?
Check out these 16 pools that take the cake.
Marina Bay Sands, Singapore
Warning: If you're at all terrified of heights, we suggest staying out of this pool. The <a href="http://www.marinabaysands.com/sands-skypark/infinity-pool/">infinity pool</a>, 57 stories in the sky, offers insane views of Singapore below.
The Joule Dallas
You'll feel as though you're swimming off the edge of the pool at the <a href="http://www.thejouledallas.com/poule.htm">Joule Dallas</a>. The heated rooftop pool extends 8 feet past the hotel, to give guests the impression they're swimming in the air.
Many believe that often-photographed infinity pool, with sweeping views off Santorini, is one of the best in the world.
Hotel du Cap Eden Roc
Set along the coastline of Cap d'Antibes sits the famous (and famously celeb-heavy) Hotel du Cap Eden Roc. Even more fabulous? The hotel's pool that juts into the Sea below it.
The Standard, LA
Set on the 12th floor of this downtown LA hotel, the L-shaped pool at <a href="http://standardhotels.com/downtown-la/food-drink/the-rooftop">The Standard </a>offers sweeping views of the city below it--and a vibrant cocktail scene to boot.
