Located on the Franco-Spanish border, the Col d'Ibardin separates the Pyrénées-Atlantiques in France from the foral community of Navarre in Spain. In addition to its many ventas, the pass offers a breathtaking view of Saint-Jean-de-Luz and its bay.

Ascent to Col d'Ibardin from Bera

Highlight (Segment) • Mountain Pass

Much of the climb is in shade. Due to the shops on the pass there is usually quite a lot of traffic on Sundays. Especially on the French side.

Lantxurda Tunnel

Recommended to bring lights. The longest tunnel, despite having light sensors, often does not work. Be careful that there were landslides on the shore.

In Endarlatsa there is a sign that the section is cut. After doubting whether to go on the road, I saw that a group of people were coming by cycling and I asked them about the state of the road: it is perfectly fine. Well, almost, removing 10m past the old San Miguel station, the rest is perfectly cyclable.
