オッセ・アン・アスプの峠・トップ15

A legendary category 1 pass. Easier from Bielle because the magnificent Benou plateau offers a gentler incline before the final climb.

Ascent of the Marie Blanque pass from Bielle quite easy and from Escot a wall🥵

Often used by the Tour de France, the Col de Marie-Blanque is less steep from Bielle than from its other side, thanks in particular to the passage through the beautiful Bénou plateau. The average gradient is 5.4%, with some sections reaching over 11%.

Without a doubt, the Col de la Piedra de Saint Martin or Pierre Saint-Martin is one of the Top 10 in the whole of the Pyrenees. Without exceeding 2000 metres of altitude, it is a very long pass, with a lot of accumulated gradient (due to the innumerable French slopes, the gradient is 1,450 metres), with very hard slopes and several kilometres above 10%, with wonderful landscapes and panoramic views and with little traffic, except for the slopes crossed by the main road (D132 in France, the NA 137 in Spain). It is a pass with many slopes; in Europe there are few other passes that have as many slopes as this one (col de Turini, Passo delle Erbe, would be comparable in number of slopes approximately). I have only climbed it by 2 slopes: (i) my first time was from Lourdios Ichère, crossing the col de Labays and the col de Soudet. Simply spectacular; (ii) I have subsequently climbed the Spanish side on several occasions, which is unique, and which starts from Belagua and crosses the Belagua cross-country ski resort to reach the mountain pass. It is also very beautiful, with a landscape and views different from the north-east side. If I had to choose one of the two, I liked the north-west side better because it is more remote, harder and in my opinion more authentic. It is also a culturally special mountain pass because the Tribute of the 3 cows takes place on its summit every 13th of July, which is considered the oldest treaty in force in Europe. So... you know... you cannot miss the opportunity to come here and enjoy this wonderful jewel of the Pyrenees!!!!

I would not recommend right now. They recently did a chip and seal so a LOT of loose gravel. I live in the area and even the road to Osse en Aspe.

A very irregular climb, with even a descending passage, which gives the opportunity to recover after a few slightly steeper passages. But not really any big difficulty on this pass.

Culminating at 1,540 meters above sea level, the Soudet pass is one of the first to be encountered from the Atlantic coast. The various climbs that lead to it are relatively long and maintain low average percentages despite a few passages around 10%.

The Col de Marie-Blanque is an emblematic passage of the Tour de France which peaks at 1,035 meters above sea level. Its ascent from Louvie-Juzon is 15 kilometers long for an average of 4.1% with passages at 8.5%. Marie-Blanque marks the border between the beautiful valleys of Ossau and Aspe. In the middle of the climb, the pretty Bénou plateau offers a portion of respite in a remarkable setting.
