Siam Park is a water park in Costa Adeje, a coastal suburb in Tenerife, Canary Islands. Siam Park features a Siamese theme, and claims to be the most spectacular water attraction in Europe. The park was opened by the Princess of Thailand Maha Chakri Sirindhorn. The principal owners are Wolfgang Kiessling and his son Christoph. A second park is planned for the neighbouring island of Gran Canaria.
