Cabo Ogoño & the Urdaibai Estuary Viewpoint
Rising 300 metres sheer from the water at the eastern edge of the Urdaibai Biosphere Reserve, Cabo Ogoño is the tallest sea cliff on the Iberian Peninsula and one of the least-visited dramatic landscapes in the Basque Country. Most visitors to Bermeo never make the short detour, which means you may have this jaw-dropping perch entirely to yourself.
The Cliff & the Biosphere
The cape forms the eastern wall of the Urdaibai estuary, a UNESCO-designated biosphere reserve where the Oka river meets the sea in a mosaic of tidal marsh, reed beds and oak woodland that shelters over 200 bird species.
From the cliff-top path above the village of Elantxobe — a tiny, almost vertical fishing village clinging to the cliff face below — the view takes in the full sweep of the estuary, the wetlands and the Cantabrian mountains beyond.
Elantxobe Village
The village of Elantxobe itself, accessible by a narrow switchback road from the BI-2238, is one of the most extraordinary settlements on the Basque coast: streets so steep that the local bus uses a rotating platform to turn around, and houses stacked like colourful dominoes above a tiny harbour.
Stop for a coffee at Bar Mendi on the main street and ask the owner about the cliff-nesting griffon vultures — a colony roosts on the Ogoño face and can often be seen soaring on thermals in the morning.
Walking & Birdwatching
A signed trail from Elantxobe climbs through holm oak to the cliff-top in about 45 minutes, emerging onto open heath with vertiginous views straight down to the sea and across to Bermeo's harbour mouth.
The Urdaibai marshes below are best explored by kayak or canoe from the village of Mundaka (10 minutes by car) — several outfitters offer guided estuary paddles through the reed channels at low tide.
