St. Louis Aquarium at Union Station
A compact family aquarium inside historic Union Station, moving from river systems to ocean habitats with touch experiences and a shark gallery.
Artwork inspired by Fred Conway
St. Louis Aquarium uses the historic Union Station setting to move from Missouri and Mississippi freshwater life toward global ocean habitats. That local-to-marine sequence gives Shark Canyon more meaning than approaching it as a standalone tunnel.
Allow the route to slow at touch habitats and smaller river exhibits, then revisit a tank after the initial crowd moves on. Admission permits same-day re-entry, making a meal or Union Station break useful for families and visitors managing sensory load.
- Plan
- Check daily schedule
- Best pace
- Fewer habitats, longer looks
- Allow
- 2 hours to full day
Quick guide
- Start
- Map one loop
- Remember
- Visibility is never guaranteed
Plan around animals, not a checklist
- Begin local
- Compare native river fish, water conditions, and human pressures before entering marine galleries.
- Shark Canyon
- Watch buoyancy, turning radius, and vertical use of the 250, 000-gallon habitat instead of only close passes.
- Touch carefully
- Follow staff direction and wash thoroughly; touch-habitat water may contain shellfish products.
- Crowds
- Use same-day re-entry or the Calming Corner when a busy gallery makes observation difficult.
Good to know
The route begins with Missouri and Mississippi freshwater life before reaching the 250,000-gallon Shark Canyon, making local waters the conceptual starting point rather than an afterthought.
