San Sebastián Aquarium
Best time to visit
Hit the shark tunnel right at opening on a weekday morning, before tour groups arrive. Feeding sessions are the liveliest moments of the day, so ask at the desk for the exact schedule.
Budget tips
Adults pay around €15, with reduced rates for kids, seniors, students, and children under 4 who enter free. No extra fees hide inside, so the only add-on worth weighing is the café, which undercuts the port restaurants by a few euros.

About
Quick facts: Inside the 1868 fish market building, a single 9-meter tunnel carries you through a 360,000 liter tank where sandbar sharks and giant groupers drift overhead. Upstairs, the maritime museum holds preserved species in jars dating from the 1920s plus a full whale skeleton suspended over old fishing gear.
Highlights: Few people notice that the shark tunnel cuts straight through the hall where fishermen once auctioned the day's catch, so you move through living memory rather than an ordinary exhibit. Show up for feeding time when sandbar sharks and moray eels surge past the glass while a keeper names each species from the tunnel.
Insider tips
- Time your arrival for the daily feeding session, typically mid-morning, and claim a spot at the far curve of the tunnel for the closest shark passes.
- Photographers should leave the flash off and angle away from the curved glass, which reflects overhead lights and ruins clean shots.
- The narrow tunnel gets shoulder-to-shoulder at weekends, so target the final hour before closing when the place empties out.
- Comfortable shoes matter more than you think; the museum winds up several floors and the whale skeleton is easy to overlook from the main ramp.
