Aquarium of San Sebastián

Getting around: At the base of Monte Urgull by the old harbor, an easy walk from Parte Vieja (the old town).
Hours: Typically open daily, roughly 10:00-19:00 (extended hours in summer, shorter in winter).

The Aquarium of San Sebastian sits right on the old harbor, built around a historic building that originally housed the city's oceanographic society, and it combines a maritime history section with a modern aquarium, including a walk-through tunnel with sharks and rays overhead. It's a smaller, more manageable aquarium than the big city-scale ones elsewhere in Spain, sized appropriately for a couple of hours rather than a full day.

Its harborside setting makes it easy to combine with a walk along the port or up Monte Urgull just behind it, and it's a solid option for families or for a rainy-day alternative to the beaches nearby.
