The Rio Urumea enters the city of San Sebastian in the district of Loiola and runs out into the Cantabrian Sea on the Bay of Biscay. Both banks of the river have lovely, elegant walkways and shady avenues. The Puente del Kuraal bridge, with its impressive lamp posts, the older Santa Catalina and María Cristina, with its dragons and all sorts of sculptural motifs, mark out the different stretches of the river before it runs into the sea.
