The world's biggest pool at Algarrobo

The world's biggest recreational pool listed by the Guinness Book of World Records is at San Alfonso del Mar, Algarrobo, Valparaiso, central coast of Chile. You have to use a sailboat to complete the 1000-meter by 19-acre pool from end to end. It gets its water supply from the Pacific Ocean. With a depth of 115 feet, it is also the world's deepest manmade pool.

To get to the pool, ride a bus from Santiago's Terminal Metro Pajaritos. Ask to be dropped off to Valparaiso. From there, you can just take a cab to San Alfonso del Mar.
