Part of the charm of the greenways lies in venturing off the beaten track; do take a detour to Bazas, an ancient fortified town whose imposing cathedral is listed as a World Heritage Site on the Routes of Santiago de Compostela.
Stroll through the narrow streets lined with half-timbered houses, and enjoy a break in the Jardin du Chapître, which backs onto the cathedral and offers a lovely view of the Beuve valley and the ramparts.

A greenway, shaded by deciduous trees and pines, leads us to Captieux.
