Route 3. Portugalete, Santurtzi and Zierbena

The Mouth of the Estuary and the Bay of Abra

This route starts in Portugalete, the town where some of the most recognised and iconic pieces of Bizkaia’s industrial heritage can be found, including Vizcaya Bridge, declared a UNESCO World Heritage Site, and the spectacular work of engineering, the iron jetty, and Rialia, a museum displaying a significant collection for visitors to better understand the industrial and seafaring past of Bizkaia. From here, you’ll go to Santurtzi and its maritime museum as well as the Agurtza Tuna Fishing Boat. You’ll wrap up this seafaring-themed day with a visit to Zierbena, a fishing port with a long-standing tradition
