Route that climbs up to the university from Leioa metro station and reveals other natural treasures of Leioa.

We start from Leioa metro station and take Sabino Arana street to Lehendakari Agirre square. There we turn off towards Doctor Luis Bilbao street, until we reach the footbridge over the Avanzada, next to the Municipal Conservatory. We cross it and take Mendibil Street to Mendibile Park, from where we take the Santsoena walkway that leads up to the University. We enter the university grounds between the Faculties of Education and Fine Arts and soon find the access to the Arberetum, which we take to go down to the area around the Lertutza reservoir. We go up the geological walkway to the east entrance and, first along the Via Apia and then along the Via Aemilia, we come out again at Santsoena. To go down to Leioa we use Universidad and Elexalde avenues, and to return to the metro, we cross the Boulevard and go along Sabino Arana avenue.
