Lofty peaks, rivers and a stunning lake

This ride sets off from Laruns leading you right up to Lac de Bious Artiques. The lake is framed by the Pic du Midi d’Ossau and is simply stunning. The climbing begins relatively quickly as you leave Laruns and work your way up the valley. As you work your way up the valley you will trace the Gave d’Ossea river all the way to the small commune of Gabas. Here the river joins up with the Gave de Bious and the gradients begin to rise. Enoy the spectacular scenery all around as you are well and truly in the heart of the mountains.
