The tunnel runs through the Oceanarium, a 3.7-million-liter tank 36 meters wide and 5 deep, putting you in the middle of the open water instead of behind a wall.
What to look for
- One tank holds about three-quarters of the aquarium's roughly 5 million liters of water
- 11,000 animals and 451 species across 35 tanks
- Large fish moving alongside you in the tunnel, not only overhead
On the Port Vell harborfront; opened 1995. The tunnel's the main draw — go there first, before crowds build.
