Col de la Pierre St Martin

Col de la Pierre Saint-Martin is a mountain pass on the France-Spain border in the western Pyrenees in the department of Pyrénées-Atlantiques and Navarra. The climb from the Spanish side was used in the 2007 Tour de France.

Close to the summit of the pass, there is the ski station of Arette-Pierre-Saint-Martin.

In 2015, on Bastille Day, the tenth leg of the Tour climbed the Col in the other direction, from Arette up to the village of Pierre Saint Martin, which hosted the end of a stage for the first time ever.Every year on 13 July since 1375, the ceremony of the Tribute of the Three Cows takes place on the summit of the mountain pass.
