What is the largest waterpark in Europe?

Siam Park is the biggest water park in Europe. Situated in Adeje, in the south of Tenerife, the park is home to an incredibly long network of impressive water slides.



Siam Park, located in Costa Adeje, Tenerife (Spain), is widely recognized as the largest and most spectacular waterpark in Europe. Spanning roughly 185,000 square meters, the park is famous for its immersive Thai-inspired architecture and lush tropical landscapes. It holds numerous world records, including the highest artificial wave in the world at its Wave Palace, reaching up to 3 meters. Iconic attractions include the Tower of Power, a 28-meter near-vertical slide that plunges through a shark-filled aquarium, and the Singha water coaster. In 2026, it continues to be ranked as the world's top waterpark by global travel platforms. For those looking for a different kind of "large," Tropical Islands Resort in Germany is technically the largest indoor waterpark by volume, housed in a massive former airship hangar, but Siam Park remains the champion for sheer scale and outdoor thrills.
