World'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.
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.
The global warming swimming pool
