Dive into a breathtaking array of beautiful and critical marine habitats, from a vibrant Philippine coral reef to lush, tropical rainforests and California's own coastal ecosystem.   

Steinhart Aquarium is one of the most biodiverse and interactive aquariums in the world. Home to an estimated 40,000 animals, representing more than 900 separate species, it offers guests an unprecedented view of underwater life and provides insights into the critical role that aquatic environments play in life on Earth.

The original Steinhart Aquarium (which opened in Golden Gate Park in 1923) was the model for many of the public aquariums that followed—and today's Steinhart carries on that tradition. The aquarium's expeditions, research, and advances in animal husbandry result in a wide range of awe-inspiring exhibits, including the world’s deepest living coral reef tank, a four-level rainforest dome, the unique, ever-changing Water Planet gallery, and more.
