Chillida-Leku is an open-air museum near the city of Hernani, about an hour and a half from Bilbao, dedicated to the Basque sculptor Eduardo Chillida. Around 40 of his monumental steel and granite works are dotted through meadows and woodland, with smaller pieces displayed inside the restored 16th-century Zabalaga farmhouse. The grounds are peaceful and easy to wander, and there’s also an organic café and shop on site.

A winding stone bridge links the mainland to this rocky islet, followed by 240 steps up to the small hermitage of San Juan de Gaztelugatxe. The chapel dates back to the 10th century, although it has been rebuilt multiple times following fires and pirate attacks. Even if the chapel is closed (which it often is), the climb is worth it for the stunning sea views, the cliffs carved into arches, and the remote, windswept feeling at the top - Game of Thrones fans will recognise the setting as Dragonstone. It’s about a 45-minute drive from Bilbao. You can also take a bus to Bermeo, a fishing town nearby, and continue by taxi or local bus. The trail is steep and uneven, so good shoes help.

Visit the Sealife Centre and find out about the fascinating world of fish. This is a thrill for both adults and children. See everything from small seahorses and starfish to sharks and stingrays. Do not miss the shark tunnel and a pool where visitors are allowed to physically touch marine creatures.
