Barcelona Aquarium (L'Aquàrium)

L'Aquàrium de Barcelona is one of Europe's most important aquariums dedicated to Mediterranean marine ecosystems, located at Port Vell in Barcelona. Opened in 1995, the facility houses over 11,000 animals from 450 species in 35 tanks totaling 6 million liters of water. The star attraction is the Oceanarium - an 80-meter long underwater tunnel allowing visitors to walk through while sharks, rays, sunfish, and schools of fish swim overhead and around creating immersive experience. The Mediterranean tanks showcase regional marine life including seahorses, octopuses, moray eels, and colorful reef fish native to local waters, emphasizing the biodiversity of the Mediterranean Sea often overlooked. Tropical tanks feature coral reefs with clownfish, surgeonfish, and exotic species from around the world. The Explora! area is an interactive space designed for children featuring touch pools where kids can safely handle starfish, sea cucumbers, and other marine creatures under supervision, tide pool simulations, and hands-on exhibits explaining marine biology. Planeta Aqua examines global aquatic ecosystems from mangroves to polar seas. Educational presentations occur throughout the day including shark feeding demonstrations with commentary explaining shark behavior and conservation. The aquarium emphasizes marine conservation and Mediterranean ecosystem protection. The facility includes a cafe and substantial gift shop. The Port Vell location at Barcelona's waterfront makes it easily accessible and allows combination with city sightseeing, beaches, and La Rambla. Operating year-round, it provides excellent indoor activity for hot or rainy days. With its spectacular Oceanarium tunnel, comprehensive Mediterranean focus, and central location, Barcelona Aquarium offers an essential marine life experience.
