The principal artery of communications through the commune is the D934 road, which runs south from the town of Pau, to the north, to the Col du Pourtalet. The D918 road branches off the D934 in Laruns village, and follows the Valentin before crossing the Col d'Aubisque to Argelès-Gazost in the next major valley to the east. There are no direct roads westward from Laruns.
