The Experience

Before You Go

Prepare for the 241 steps

The ascent to the hermitage is steep and uneven—sturdy hiking shoes and steady pacing will keep your knees and breath in check.

Watch the weather forecast

Coastal winds and rain can make the path slippery; check Euskalmet and avoid the climb during orange alerts.

Respect tidal timings in Mundaka

If you plan to watch surfers or stroll the estuary, tides and swell affect access to the best viewpoints and the character of the bay.

Carry small change

Cafés and local vendors in Mundaka and Gernika may not accept cards for small purchases—bring cash for snacks and souvenirs.

Local Knowledge

Hidden Gems

  • Walk the quieter viewpoints south of the islet for different coastal angles away from main crowds

Conservation Note

The route passes parts of the Urdaibai Biosphere Reserve—stay on marked paths to protect marsh habitats and follow local guidelines to limit disturbance to shorebirds.

Gaztelugatxe’s hermitage dates back centuries and was rebuilt multiple times; Gernika’s Assembly Hall and the Tree of Gernika are central symbols of Basque self-government and memory.
