L’Aquàrium de Barcelona

L’Aquàrium de Barcelona is primarily celebrated for its massive oceanarium featuring an 80-meter glass tunnel with a moving walkway. Visitors can watch sand tiger sharks, rays, and sunfish swim overhead as part of an immersive underwater experience. Across multiple exhibits, it showcases a wide variety of Mediterranean and tropical marine ecosystems.

Audience reactions are sharply divided between visitors who enjoy the sea life and critics who consider the entrance fees overly expensive for a relatively brief visit. Multiple commenters raise ethical concerns regarding marine animal captivity and debate the attraction's overall value for money.
