Aquarium San Sebastian

About

Aquarium San Sebastián, one of the city’s most beloved attractions, blends marine science with immersive storytelling to create a memorable coastal experience. Set along the harbor, it invites visitors into a world where the Bay of Biscay’s ecosystems come alive through vibrant tanks, graceful sharks, and the iconic 360‑degree ocean tunnel. The historic building, part museum and part modern aquarium, also explores the region’s maritime heritage, offering insights into Basque seafaring traditions and early ocean exploration. Families, students, and ocean lovers find it an inspiring space that balances education with wonder, making it a cornerstone of San Sebastián’s cultural landscape and a highlight for anyone drawn to marine conservation and coastal discovery.
