On page 345 of the 2026 Spain Guidebook (French Basque Villages, Ainhoa, France) , a scenic detour to Chapelle de Notre-Dame d"Aranazau (d'Auberpine)/oratoire is mentioned, "worth the steep detour for drivers". Best I can tell after looking at Google Maps & Google Street View, this dirt road is prohibited for cars and motorcycles.
Can anyone confirm this route is for hikers only?
