About St Louis Aquarium
Explore life under the sea at St Louis Aquarium at Union Station!
Located in what was once one of the busiest passenger rail terminals in the entire world, the St. Louis Aquarium at Union Station is where the whole family can be taken on an aquatic journey like no other!
What if we also told you that St Louis Aquarium also had a 250,000 gallon shark tank, and a whopping 13,000 animals that call it home, all of which represent 257 species? With 44 exhibits spread across 120,000 square feet, it's an amazing experience for all ages!
Kids can come face-to-face with a prehistoric paddlefish (sounds fascainting!) in the Confluence Gallery, or see first hand some Zebra sharks in Shark Canyon. They can even get their hands tickled by the Doctor fish, or feel the rubbery skin of a ray! Can you imagine what that would be like?
The whole family can also meet some of the aquarium's amazing program ambassadors during personalized animal encounters, so there really is something for everyone!
