A very pleasant greenway along the Albarine River and the railway line! Ideal for connecting two different starting points for the ascent of the famous Col de Portes.

Nice route of beautiful paths in the undergrowth, some singles without difficulties, some viewpoints on the heights of Vaux, Lagnieu. Attention ⚠ small single going up between Vaux en bugey / Bramafan very steep and narrow, the second part of the descent after Bramafan is technical slope and slippery rocks.
