L’Aquàrium de Barcelona

L'Aquàrium de Barcelona at Port Vell is one of Europe's largest aquariums and consistently ranks as one of Barcelona's top family attractions. With over 11,000 animals across 35 tanks, the aquarium takes visitors on an underwater journey through Mediterranean ecosystems, tropical coral reefs, and the deep ocean — all without leaving dry land.

The undisputed highlight for kids of all ages is the 80-meter walk-through underwater tunnel, where sharks, giant rays, and thousands of fish glide just inches above your head. It's one of those experiences that genuinely makes both kids and adults stop in their tracks. Young children are particularly captivated by the scale and closeness of the marine life.

For the littlest visitors, the Explora! section is specially designed for children under 6, with touchpools where kids can handle starfish and sea urchins under supervision, and child-height viewing windows throughout. The aquarium also features a planetarium, scuba diving experiences for adults, and a small shark feeding observation opportunity.

Plan for at least 90 minutes; families with young explorers often stay the full two-plus hours. Book online to save money and skip the often-long entrance queue.
