Siam Amazing Park in Khan Na Yao is Bangkok's largest combined amusement and water park, spanning more than 100 acres along Suwinthawong Road in the eastern suburbs at 203 Suan Sayam Road, Bangkok 10230. The park opened in 1980 and has run continuously since, placing it among the oldest operating theme parks in Thailand.
The amusement section holds roller coasters along with a giant swing and a wave swinger as its main mechanical rides. A separate water park section contains wave pools, a large lazy river circuit, and multiple speed slide lanes across an adjacent outdoor area.
Both sections fall under one standard admission ticket, giving strong value compared to resort or international park alternatives. The site is large enough to fill a full day and to stay comfortable even during busier periods.
The park draws mainly from Bangkok's eastern residential districts, with peak attendance during the April school holidays. Allow around forty-five minutes of travel each way from central Bangkok. For tickets and current hours, use siamamazingpark.com or call +66 2 105 4294.
