San Sebastián Aquarium Tours and Activities

Extensively revamped in 2008, the San Sebastián Aquarium has an enviable waterside position at the foot of Monte Urgull, is one of the most up-to-date in Europe, despite its location in a 1928 building. With 31 aquaria featuring marine eco-scapes from Cantabria and the tropics, the premier attraction here is the 360-degree perspex tunnel that dives through the Oceanarium while more than 40 species of fish, including bull sharks, turtles, sinister stingrays and jellyfish, swim merrily past.

A small museum of marine history displays the bleached skeleton of a whale caught off the Atlantic coast in 1878, and a smattering of fascinating whaling and fishing boats that showcase San Sebastian’s enduring relationship with the sea.
