Many travelers enjoy a great city like Bilbao but are unaware that Bilbao would be nothing without the surrounding villages along the Nervión estuary at its exit to the sea. This tour runs through all the towns on the two banks of the estuary, knowing its history and visiting all its most emblematic corners, from Barakaldo to Algorta, passing through Santurce. Cross the estuary on a historic bridge such as Portugalete in an authentic experience.
