10 Fascinating Swimming Pools

1World's biggest swimming pool

If you like doing laps in the swimming pool, you might want to stock up on the energy drinks before diving in to this one. It is more than 1,000 yards long, covers 20 acres, has a 115ft deep end and holds 66 million gallons of water. The Guinness Book of Records named the vast pool beside the sea in Chile as the biggest in the world. This pool took five years to build, cost nearly £1billion and the annual maintenance bill will be £2million. Its turquoise waters are so crystal clear that you can see the bottom even in the deep end. It dwarfs the world's second biggest pool, the Orthlieb, nicknamed the Big Splash, in Morocco, which is a mere 150 yards long and 100 yards wide. An Olympic size pool measures some 50 yards by 25 yards.

2Devil's pool

Victoria Falls is on the border between Zambia and Zimbabwe. It is 360 feet tall. At the top is a natural rock pool, called Devil's Pool, where the water is relatively calm. From September to December, when the water level is low, you can swim in Devil's Pool. The pictures are bound to make you just a little nervous. Or a lot.

3Hanging pool

This architecturally-daring pool, designed by Architexas, sits atop The Joule hotel in Dallas, Texas. Ten stories above the ground, the pool projects eight feet over the edge of the building and hangs directly above Main Street, giving dippers dazzling downtown views.

4World's largest indoor swimming pool

“Ocean Dome”, located in Miyazaki, it's the biggest indoor swimming pool in the world. It's 300 meters long and 100 meters wide, and it's located 500 meter from the sea. The temperature inside the pavilion is always around 30 degrees, the roof is sky-blue and it has even “clouds”. It has an artificial volcano and also an artificial wave generation system.

5World's most crowded wave pool

Don't believe the photo above? This incredibly crowded wave pool is located in Tokyo Summerland. During summer, it can get really hard to actually find some water inside this pool.

6Blood-red pool

The island of Koh Samui's infamous Chaweng Beach is littered with hotels, but none of them comes close to the Library in terms of that all-out beach bliss-out factor. This elegant and modern boutique hotel is most remarkable for its amazing blood-red pool and the tall trees that seem to grow in, around and through the building. The aforementioned red pool serves as the focal point, with daybeds, Thai antiques, and an open air mini-library.

7Playboy's swimming pool

The new Hugh Hefner Sky Villa at the Palms Las Vegas includes this Playboy pool at the top of the tower. The swimming pool is inside and the whirlpool is outside, both with amazing views of the Strip. The swimming pool covers two acres, with a DJ, outdoor concerts, three bars and twenty-seven private cabanas with a 32" flat-screen TV, refrigerator and fan.

Can you imagine the amount of semen in this pool?

8World's deepest indoor swimming pool

The Nemo 33 diving pool in Belgium is, oddly enough, over 33 meters deep. It is filled with 2,500,000 liters of non-chlorinated, highly filtered spring water maintained at 30 °C (86 °F) and contains several simulated underwater caves at the 10 m depth level. There are numerous underwater windows that allow outside visitors to look into the pools at various depths.

9The global warming swimming pool

No, New York is not underwater (yet, anyhow) – that's a clever ad for HSBC by Ogilvy & Mather Mumbai ad agency in India. The bank wanted to raise awareness of the dangers of global warming, so the clever ad guys glued an aerial photo of a city's skyscrapers to the base of a swimming pool … the effect of a submerged cityscape is fantastic!

10Infinity indoor pool

This is a cool infinity pool that looks out over a breathtaking skyline from several stories up. This is definitely a great place to enjoy the sunset at the Crown Towers Hotel in Taipa Island Macau.
