Oceans Building

The Oceans Building at the Indianapolis Zoo is one of the crown jewels of an already exceptional zoo campus, a large-scale aquarium experience contained within a dramatic structure designed to immerse visitors in the feeling of being underwater.

The building's signature feature is its massive floor-to-ceiling aquarium windows, which allow visitors to stand face-to-face with sharks, rays, and countless marine species in a way that feels humbling rather than safely distant. Young children in particular react to the scale of the tanks with the kind of wonder that is increasingly rare in an age of screens and simulation.

The dolphin presentation facility within the Oceans Building is one of the better-known experiences at the Indianapolis Zoo. Attendants demonstrate dolphin behaviors, underwater acrobatics, and the intelligence of these animals in shows that manage to be both educational and entertaining. Seating fills up, so arriving 15-20 minutes before a show is strongly recommended.

The touch tank, where kids can gently stroke stingrays as they glide past, is a perpetual highlight for younger visitors. Staff members supervise the interaction and offer guidance on proper technique, making it both safe and meaningful.

The Oceans Building is entirely climate-controlled, making it a particularly strategic destination on hot summer days or when rain moves in. It is included with general Indianapolis Zoo admission, so there is no additional cost to add it to a zoo visit.
