Ahintziaga, Mountain summit on French-Spanish border, Baztan and Saint-Étienne-de-Baïgorry, France and Spain.
Ahintziaga is a 905-meter mountain forming the boundary between Baztan Valley and Saint-Étienne-de-Baïgorry. Its slopes feature dense forests that gradually open into meadows as you climb higher.
The mountain became a natural border marker following the 1856 Pyrenean boundary treaty. This agreement established the mountain range as the official division between France and Spain.
Basque shepherds still graze their flocks on the slopes following customs that have shaped the landscape for centuries. The way they manage the land reflects a deep connection to this mountain environment.
Hiking trails to the summit begin from Saint-Étienne-de-Baïgorry with clear path markings throughout. The ascent is gradual and accessible for hikers with moderate experience.
From the summit you can see both the French Basse-Navarre region and Spanish Navarra at the same time. This vantage point creates an unusual perspective of two different landscapes meeting.
