Marineland started in 1970 as a quaint oceanarium that only offered a few pools for visitors to view. However, nowadays, Marineland has expanded and now stands as one of the biggest oceanariums operating today. Not only is the entire location one of the largest, Marineland also boasts of one of the largest water tanks in the world – one that holds about 11 million gallons of water and houses all sorts of marine-life shows that involve dolphins, whales, and even sea lions. At Marineland families can come within inches of sharks, manta rays, and dozens of other types of ocean-dwelling creatures. If you’re lucky enough, your family may even be able to experience an intimate hour of learning about dolphins and family members are even given the chance to touch them. No aquarium compares to Marineland.
