From Pau-Pyrénées Airport or the A64 motorway (exit 9.1), head towards Lescar on the D817.
Follow the D817, then the D802, and finally the N134 towards Saragosse-Oloron-Jurençon.
In Gan, continue on the N134 and then turn right (If coming from Oloron, turn left!) onto Rue du Lac/Maison Pour Tous.
Immediately turn right onto Chemin de Mesplet. Maison Tournesol is located at the top of the hill, on the left at the STOP sign.
