Beijing's Water Cube was one of the most spectacular venues at the 2008 Summer Olympic Games. You may best remember it as the place where Michael Phelps won eight gold medals. Earlier this month, on the two year anniversary of the start of the Beijing Olympics, the Water Cube was reopened to the public as Asia's largest indoor water park.
The water park takes up about half of the 130,000-square-foot (12,000-square-meter) complex and features a wave pool, lazy river, spa area, and 13 water slides and rides. One of the slides is seven-stories high! Unfortunately for locals, the entrance fee of $30 is pretty steep compared to their average income ($138/month), so the water park is geared more toward tourists. Renovations of the project cost about $50 million and was completed by planning and design firm Forrec.
