Have you ever gone sailing in a pool? It’s possible in Chile, according to our friends at National Geographic‘s Blog Central:

Covering 20 acres and stretching half a mile, the swimming hole at Chile’s San Alfonso del Mar resort is a 115-foot-deep, 66-milliongallon monster. (An Olympic-size pool is “only” 164 feet long, 6 feet 7 inches deep, 660,000 gallons.) Built for $3.5 million by the Chilean firm Crystal Lagoons, which aims to open an even vaster version in the Egyptian desert, the pool has delighted resort guests and curiosity seekers since 2007.

Pumped in from the Pacific, the water in this Chilean pool is 16°F warmer than the ocean. Photo: Eliseo Fernandez, Reuters.
