Deba (Gipuzkoa)

Deba is a small seaside town at the mouth of the Deba river on the western coast of Gipuzkoa, between Mutriku and Zumaia, with a 400 m surf beach right in front of the town and a Euskotren station in the centre. It is the western end of the Flysch Route, the 13.5 km clifftop walk from Zumaia, and the start of the coastal path to Mutriku and Ondarroa. Come for the beach, the Gothic church of Santa María and the cliffs and coves of the Basque Coast Geopark; skip it if you want a big resort with nightlife.

Getting there and parking

By train: Deba station is in the centre, on Arakistain square (OpenStreetMap), on the Euskotren line between Bilbao and San Sebastián. Zumaia, at the other end of the Flysch Route, has a station on the same network, so many walkers go one way and return by train. Check Euskotren for current times.

By car: Deba lies between Mutriku and Zumaia; the Santiago beach page of the Basque tourism board lists parking among its services. We found no official information on parking prices; the train is the easier choice on a fine summer weekend.

On foot: a seafront promenade and the coastal path both link Deba with Mutriku, 3 km to the west in a straight line.

What to see

Santa María church. In the heart of the old quarter, the church of Santa María, also known as Nuestra Señora de la Asunción, is a listed monument that the Basque tourism board calls a jewel of Basque Gothic architecture. spain.info points to its façade and atrium on Lersundi street and its Gothic cloister, and to the Baroque town hall nearby.

The estuary and the beach. Three promenades, Sorozabal, Cárdenas and Arrantzales, follow the river from the beach to the marina. The river is crossed by a 19th-century stone bridge, which the coastal path uses on its way to Mutriku.

Cliffs, coves and the flysch. East of the town begins one of the most striking stretches of the Basque coast: about 8 km of cliffs to Zumaia, protected as the biotope of the tidal platform and flysch cliffs. At low tide a flat rock platform appears below the cliffs, which the tourism board says shelters many migratory birds. The steepest cliffs are at Mendata, Sakoneta and Pikote, and the quiet coves of Mendata, Aitzuri and Sakoneta lie along this shore. Sakoneta is 3.5 km east of the town in a straight line.

Caves and the hills inland. Inland, green valleys with farmhouses suit walking, cycling and riding. The municipality has more than fifty caves and prehistoric sites. The most important is Ekain, with cave paintings, which the tourism board says was declared a UNESCO World Heritage site in 2008. A replica that you can visit, Ekainberri, is reached from the neighbouring town of Zestoa. spain.info also names the caves of Ermittia and Urtiaga.

Beach

Facts are from the Basque tourism board’s page on Santiago beach (Deba), checked November 2026.
