Sunway Lagoon is an amusement park in Petaling Jaya, Malaysia. It was officially opened by the Prime Minister Tun Mahathir bin Mohamad on April 29, 1993. It features rides in both the water park and the adjacent dry park. The park has slowly been adding rides and play areas, with the aim of substantially improving the attraction by 2008. In late 2008, new parks had been added and had cleaned the place slightly.
