There's a bunch of accommodation in the middle of Iraty ("Chalets d'Iraty) that's lovely to drive to, it's the D18 and D19 roads between St Jean Pied de Port, and Larrrau
After Larrau, if you have time, the hike to Passerelle D'Holzarte starts from the "Auberge Logibar" and is very worth it, a suspended bridge awaits you at the end of the climb
