The Aquarium de San Sebastián sits in the perfect spot on the harbour and right next to Old Town, making it an essential stop for your family holiday. This aquarium features dozens of exhibits broken up by region and houses more than 200 species of ocean life.
Like any aquarium, you’ll find the usual creatures like sharks, jellyfish, and turtles. Things get a little more interesting with the 360-degree underwater tunnel going straight through one of the tanks. There are often deals available for children, so bring the whole family.
