Cross the town and continue along a quiet route despite a small mound before a junction at km 18. Continue straight on the D27 towards Navarrenx. In good weather, the chain of the Pyrenees emerges from the south towards the Basque Country. Pass through the village of Jasse before entering Navarrenx. The fortifications of this old fortress are still visible and a detour through the alleys is necessary before leaving the bastide and turning left towards the Pont du Gave.
