Overview
Siam Amazing Park, widely known in Thailand as Siam Park City or Suansiam, is an amusement and water park complex in Bangkok’s Khan Na Yao District. The park is located in the eastern part of the metropolitan area, near Suvarnabhumi Airport, and combines a large water-park area with amusement rides, family attractions, themed exhibits, event facilities, and a scout camp. It is one of Thailand’s oldest continuously operating leisure parks and is described as the oldest amusement and water-park complex in Southeast Asia. The complex opened on 19 November 1980 under the name Suansiam. It was established with the involvement of Thai investors and was later developed under the leadership of real-estate developer Chaiwat Luangamornlert. The original concept combined a water park with a comparatively small number of rides. Over time, the site expanded into a broader destination for family recreation, school and group visits, entertainment events, and thrill-seeking visitors. The park covers approximately 100 acres and is organized around two principal areas: the water park and the amusement park. Its water attractions include a large wave pool, flowing or lazy-river facilities, speed slides, spiral slides, children’s play areas, and spa services. The 13,600-square-metre wave pool, known in the park’s promotional tradition as Talay Krung Thep, was recognized by Guinness World Records in 2009 as the largest wave pool in the world at that time. The water area has long been one of the park’s defining attractions and has helped distinguish Siam Amazing Park from Thailand’s primarily ride-focused theme parks. The amusement area contains approximately several dozen rides and attractions, including roller coasters, a free-fall tower, a log flume, observation facilities, spinning rides, family rides, and themed experiences. Vortex is a suspended looping coaster with five inversions and has been presented as Southeast Asia’s first suspended looping coaster. Giant Drop is a 75-metre free-fall tower, while Si-Am Tower provides elevated views over Bangkok. Other attractions have included Boomerang, Log Flume, Topspin, Mega Dance, Twin Dragon, Condor, Astro-Liner, and Tagada Disco. Family-oriented attractions include Dinotopia, Jurassic Adventure, and Africa Adventure, which use museum displays, animatronics, and themed journeys built around dinosaurs, wildlife, and adventure narratives. The park has also functioned as a venue for public events and popular culture. Recorded activities at the site include a Miss Thailand final, concerts, a boxing event, exhibitions of Chinese lantern puppets and dinosaur skeletons, and a music-video production by BNK48. Michael Jackson visited the park during his Dangerous World Tour in 1993, according to the park’s historical record. In the fourth quarter of 2019, the business adopted the Siam Amazing Park name as part of a rebranding. The earlier Siam Park City name nevertheless remains widely used by local residents and in historical references. The attraction continues to operate as a combined amusement and water-park destination, although detailed current ownership, attendance, executive, and financial information is not established in the supplied reference material.
History
Siam Amazing Park began as Suansiam, opening on 19 November 1980 in Bangkok’s Khan Na Yao District. The project involved a group of Thai investors and was later developed by real-estate developer Chaiwat Luangamornlert. It was conceived as a water park with amusement rides, making it one of Thailand’s earliest purpose-built leisure complexes of this type. The park expanded over subsequent decades into a large integrated attraction covering approximately 100 acres. Its water-park component developed beyond basic pools and slides to include a major wave pool, flowing-river facilities, high slides, spiral slides, children’s play zones, and spa services. Its amusement area likewise grew to include roller coasters, drop towers, flume rides, observation facilities, spinning rides, and themed family attractions. This expansion gave the park a broad audience ranging from families and school groups to visitors seeking large thrill rides. A major landmark in the park’s history was the recognition of its 13,600-square-metre wave pool by Guinness World Records. The certificate was formally presented on 30 April 2009, identifying the pool as the largest of its kind in the world at that time. The feature became central to the park’s identity and was promoted as an inland sea in Bangkok. The site has also hosted a variety of cultural, sporting, and entertainment activities. Historical records associate it with a Miss Thailand final in 1985, a Carabao concert in 1986, a boxing match later that year, and an exhibition of lantern puppets and dinosaur skeletons from Zigong, China, held from the end of 1992 into 1993. Michael Jackson visited during his Dangerous World Tour in 1993. In 2017, the park was used as a location for a Thai-language music video by BNK48. The park experienced two notable ride accidents in the late 2000s. In October 2007, an electrical malfunction on the Indiana Log Slide resulted in one fatality and six injuries; the ride was later removed. In March 2008, a joint on the Super Spiral waterslide failed, causing a collapse that injured 24 children. These incidents form part of the site’s documented history, but the supplied material does not establish subsequent regulatory findings or broader legal outcomes. In the fourth quarter of 2019, the park was rebranded Siam Amazing Park. Siam Park City remains the name by which many local visitors know the complex, and it continues to appear in historical descriptions and informal usage. The attraction remains a combined water park, amusement park, family entertainment venue, and event destination in Bangkok.
