About
Quick facts: Over 8,000 marine creatures from 450 species live in an enormous 7 million-liter tank. The central tank simulates an open ocean habitat with a 5-meter deep main tank visible from multiple levels.
Highlights: One of the largest indoor aquariums, the main tank mimics the North Atlantic Ocean complete with sunken ships and rocky reefs. Visitors can watch a 23-ton manta ray gracefully glide through clear waters alongside sharks and colorful fish.
Insider tips
- Wear comfortable shoes for walking and standing as the aquarium is spread over multiple levels.
- Bring a camera with a good lens to capture vibrant underwater scenes through glass walls.
- Skip weekends and mid-afternoon to avoid peak crowd times and long lines.
- Stop by the observation deck at the top level for panoramic views of the harbor and city skyline.
