Our summer world tour of water park suggestions is coming to a close. In a place where the temperatures are nice all year long. Tenerife Island, on the the Spanish Canarian Islands. The park is called Siam Park and combines pumping water rides and spectacular scenery, a water kingdom and beach club with Thai decor on all of its rides, park buildings, and restaurants granted to the park’s designer, Christoph Kiessling, by the Thai royal family. The Tower of Power is the scariest water park ride in the Park and one of the steepest in world ( 76 metre drop) with a shark tank at the bottom. Check our full guide here.
