Mutriku combines steep streets and historic palaces with harbour life, coastline and geological features. If you would like to combine culture and nature on your trip, the town offers a range of highlights: the history of its Old Town, its maritime heritage, the black Flysch cliffs and the limestone-rich Arno mountain range.

Old Town and maritime heritage

Mutriku’s Old Town was declared a historic monument complex in 1995. Its townscape is defined by steep, narrow streets and manor houses and palaces dating from the 15th to the 18th century. One example is Palacio Arrietakua: this inhabited palace, which has been preserved intact to this day, dates from the 18th century and belonged to seafarers Antonio de Gaztañeta and Cosme Damián Churruca.

The Torre de Berriatua, also known as Sulengua, also tells the story of the town. It survived the devastating fire that ravaged Mutriku in 1543 and formerly served as a watchtower for the harbour. Today, it is considered the tallest surviving medieval tower house in Gipuzkoa. The church of San Andrés de Astigarribia is one of the oldest churches in the province and one of its few pre-Romanesque examples.

The “Mutriku marinera” guided tour explores the town’s maritime history through its houses and palaces. It starts at the tourist office on Txurruka Plaza. This distinguishes it from the guided tour of the wave energy plant, which starts at the harbour’s old swimming pool.

Sea, harbour and Flysch

Mutriku beach has two natural swimming pools. Visitors can swim, windsurf, canoe, bodyboard, play volleyball, scuba dive and fish for sport there; some services are seasonal. For a different perspective on the coastline, the “Siete Playas” boat tour departs from the harbour and travels to the black Flysch cliffs between Mutriku and Saturraran beach.

The “Nautilus, fossils of flysch” guided tour starts at the Nautilus Centre in Mutriku and combines a visit to the Nautilus Museum with a boat trip to the black Flysch cliffs. Whether the boat trip takes place depends on the weather and sea conditions. The “Flysch en familia” activity combines a participatory fossil workshop at the Museo Nautilus with a boat trip from Mutriku to Saturraran beach. Dates and prices are subject to change.

The black Flysch on the cliffs of Mutriku formed in deep channels created by tectonic movements as the Bay of Biscay opened. Giant ammonites are another of Mutriku’s geological features. The cliffs of Siete Playas can be reached from Saturraran beach or Mutriku harbour, but only at low tide; the area is dangerous.

The marina was established in 2014 in the historic harbour, preserving its layout as a traditional fishing port. It has 301 berths for boats up to 14 metres long. Mutriku’s wave energy plant was the first facility to generate electricity from the power of waves.

Local cuisine and market days

At the annual Día del Verdel, local chefs serve mackerel prepared in different ways: as pintxos, grilled and in marmitako. The exact date varies. The “Azoka Txikia” market takes place from March to December on the second Saturday of each month at Beheko Plaza. Both a recurring culinary event and a regular market day are part of the town’s annual calendar.

Arno and routes through the landscape

The limestone-rich Arno mountain range is part of the EU’s Natura 2000 network and was designated a Special Area of Conservation in 2013. Its holm oak stands (Quercus ilex) are among the most significant in the north of the Iberian Peninsula. One route starts and ends at the Ermita de San Isidro; along the way, information panels describe geological and ethnographic features of the surrounding area.

Another circular route starts and ends in Mutriku and passes over the peaks of Arno, Jangoikomendi and Tontorramendi. Their elevations can be compared directly: Arno reaches 601 metres, Jangoikomendi 528 metres and Tontorramendi 386 metres. The Arno mountain range also shapes the landscape underground: a river disappears here, flows underground through the entire range and resurfaces in Astigarrabia before joining the Deba.

Visiting Astigarrabia

Bus groups cannot travel to Astigarrabia by bus. They must leave their vehicle at a designated point on the GI-3230 and walk about 220 metres along the old road, accompanied by the guide. This specific access information is important when planning a visit if you are interested in the church of San Andrés and the neighbourhood.
