4. Largest Indoor Wave Pool.
West Edmonton Mall in Edmonton, Alberta, Canada, is the World Waterpark, which features the world’s largest indoor wave pool, called Blue Thunder. Blue Thunder possess four active wave bays, each containing two panels powered by a 1,500-horsepower hydraulic implement. There are two additional wave bays that have been deactivated, a consequence of overwhelming injury due to the excessive intensity of the waves! When all panels were enabled, the waves were too high and rough for even the most experienced swimmers.
