Where Presunto culpable was filmed

The town in Presunto culpable is Mundaka, and the harbour is its centre. The production company Boomerang TV lists the harbour, streets, town hall, breakwater and seafront of Mundaka among the locations, and all of them lie within a few minutes' walk. The town hall stands right beside the quay, and from the breakwater you can see the mouth of the estuary with Laida beach opposite.

Locals took part as extras and the town's bars and restaurants worked with the crew during filming, as Noticias de Navarra reported on the day of the premiere. Turismo Urdaibai suggests wandering the little streets, spending a while at the harbour and climbing to the Portuondo or Atalaya viewpoints. Mundaka is also a surf town: its left-hand wave starts at the sandbar and ends at Laida.

Antena 3 presented it as “the place where it all begins”. Alejandra Onieva shot her first day here, a sequence with Miguel Ángel Muñoz that opens the story. The hermitage also appears in many of the series' promotional photos, as FormulaTV points out.

It stands apart from the town, on a small headland by the sea. Turismo Urdaibai describes it as a tall, bulky hermitage, and its surroundings have become a seaside recreation area. It is a short walk from the harbour. This guide covers the exterior only; if you want to see the inside, ask at the Mundaka tourist office.

The bird centre in the Urdaibai reserve is run by the Aranzadi science society, which described the crew's visit on its website. The most important sequences were shot at the large viewing hide over the marsh, and Carol Rovira, who plays Maite, took part in a real bird-ringing session.

It is about 4.5 km from Gernika, on the right bank of the River Oka. Opening hours change with the season. From November to 27 February it opens on Saturdays, Sundays and public holidays from 10:00 to 16:00 and is closed on weekdays. In July and August it opens every day from 10:00 to 18:00. The website does not publish prices, so check fares on the official site. The two observatories on the outdoor circuit are free to enter.

Laida is the stretch of sand you see from Mundaka harbour, across the river mouth. Boomerang TV and Naiz include it among the filming beaches along with Laga and Arribolas. Turismo Urdaibai notes that Mundaka's famous left-hand wave ends here, having started at the bar opposite.

At low tide the sand stretches far out towards the estuary and you can walk along the shore with Mundaka in the background. The series was shot between November and April, so you see it on screen in winter light and almost without people. Bear in mind that the estuary water runs strongly when the tide turns.

Laga is a few kilometres from Laida, already on the open sea and beneath the limestone wall of Mount Ogoño. The production company lists it among the filming beaches, and it is easy to recognise by the grey crag that closes the beach on the west.

It is a wide beach, with a lone house at the foot of the mountain. In winter, when the series was shot, the surf is usually strong and the mood suits the tone of the series. From here the road continues along the coast to Elantxobe, if you want to finish the route in another fishing village. Check the state of the sea before swimming out of season.

Bermeo is a few kilometres from Mundaka and the production company lists its streets and harbour among the locations. In February 2018, as the third month of filming was about to end, Deia reported that the crew was working in Bilbao, Gaztelugatxe, Mundaka and Bermeo, and Boomerang TV executive producer Josep Cister thanked the councils of Mundaka and Bermeo.

The old harbour is the most photogenic part: narrow coloured houses, café terraces and the old quarter rising behind. Above the quay stands the Ercilla Tower, the oldest civil building Bermeo still has, which has housed the Fisherman's Museum since 1948; check opening times on its official website. Turismo Urdaibai counts it among the most important inshore fishing ports on the Cantabrian coast.

Matxitxako is the most prominent cape on the Basque coast, between Bermeo and Gaztelugatxe. The production company's note speaks of the “Matxitxako Lighthouse Forest and the cape viewpoint”, and Naiz repeats the list. The working lighthouse is a stone tower with white outbuildings and red roofs; a few metres away stands the old lighthouse.

The working lighthouse is in a closed compound and is seen from outside; you can walk up to the old one. The walk to the viewpoint is short and on windy days the sea breaks hard against the cape. From here you can see the coast towards Gaztelugatxe, the next stop.

Antena 3 devoted a report to this setting with Itziar Atienza and Alejandra Onieva, who play Ainhoa and Anne. Both agree the place suits the story and their characters. It is the rocky islet with the hermitage on top, joined to the land by a stone bridge and a long flight of steps.

It is a protected natural area. On the dates marked in the official calendar, booking is compulsory; it is done at tiketa.eus, with a maximum of 10 tickets per request, and if you do not turn up within 60 minutes of your slot you lose the place and cannot book for a year. Outside those dates the website does not require a booking. Drones, loose dogs and leaving the paths are prohibited. The official website does not publish a price.
