Great views over the valleys of St Jean Pied de Port and Aldudes make this worth doing on a clear day. Easy navigation on the well-marked GR10.
900m of ascent, 5 hours
Take the turn off to the village of Lasse from the St Jean Pied de Port to Saint-Étienne-de-Baïgorry road. From Lasse drive 2 km uphill on small roads marked with the red/white GR waymarks. Park at a wide junction, near a barn.
