Mundaka, Bizkaia – Estuary and Coastal Village on the GR® 38 Route

Tidal landscapes, Atlantic views, and the meeting of river and sea

Mundaka lies along the GR® 38 Wine & Fish Route at the mouth of the Urdaibai estuary, where tidal waters meet the open Atlantic and the inland journey reaches the coast. Arriving from Gernika-Lumo, the route follows the estuary shoreline through wetlands and open tidal landscapes before reaching the harbour and sea-facing streets of this historic fishing village.

The settlement is arranged around a natural harbour with narrow streets rising above the waterfront. The estuary widens here, opening toward Laida Beach and the Bay of Biscay, while wooded hills and tidal flats frame the surrounding landscape.

Approaching Mundaka, the GR® 38 follows quiet lanes and shoreline paths through the Urdaibai UNESCO Biosphere Reserve. The transition from inland valleys to tidal water and open sea creates a strong sense of arrival at the Atlantic coast.

Mundaka is internationally known for its long left-hand surf break, but beyond the waves the village retains a strong maritime character shaped by fishing traditions and coastal life. Cafés, small restaurants, accommodation, and essential services make it a practical stopping point before the final stage to Bermeo.

Leaving Mundaka, the GR® 38 continues along the coast toward Bermeo, following shoreline paths and coastal terrain to the fishing port that marks the northern end of the route.
