OdySea is the largest aquarium in the Southwest and one of the most inventive aquatic adventure complexes in the world. Nine massive globe-shaped aquariums filled with colorful tropical fish dangle over visitors’ heads in the lobby. The fully enclosed Deep Ocean escalator, another first of its kind, transports patrons through a display of giant rays, sea turtles, and white tip reef sharks. Families can explore penguin and sea otter habitats as well as explore the immersive SeaTREK helmet diving experience. Additionally, OdySea is not alone. It’s part of a large complex including Butterfly Wonderland, the largest butterfly pavilion in America, and Dolphinaris, a swim-with-the-dolphins attraction.
