Marineland is a themed amusement and animal exhibition park in the city of Niagara Falls, Ontario, Canada. Owing to its proximity to the falls and other natural park areas and its blend of animal attractions and rides, it is one of the main tourist destinations in Niagara Falls, Canada.The park was founded by John Holer, a Slovenian immigrant who had worked for circuses in Europe before coming to Canada in the late 1950s.
It first opened in 1961 as "Marine Wonderland and Animal Farm". Holer welded two large steel tanks together and brought in three sea lions and charged one quarter for admission and another to feed the animals. The attraction also featured an underwater show featuring two female swimmers. In 1964, Holer added two dolphins were added along with a few other animals and the attraction became known as "Marineland And Game Farm".
By 1966, a 2,000 seat "aquatheatre" was completed along with a "grotto" of aquariums and shops.Marineland is open from the Victoria Day weekend through to Canadian Thanksgiving weekend in October. Rides operate until nightfall.
