The popular water mass aquarium is the first of its kind in the world, and displays a three-dimensional reconstruction of seas and rivers. You can enjoy the dynamism and cooling sensation of exploring the water. While it is a compact space, it offers guests to experience the solace and tranquility of an out-of-the-ordinary underwater world.
