After the college, go down chemin Sartoulet, then left onto chemin de la Vieille Église. A path descends steeply to the right and leads to a fountain (la Houn de Caouté). Go back and forth and continue straight ahead, then go around the Arènes. Turn right into rue du cimetière, cross the esplanade and take rue du Béarn, which joins the square.
