A Montfort-en-Chalosse-Poyanne-Préchacq-les-Bains, circuit entre Adour et Chalosse

This is a lovely loop in Chalosse, along trails and secondary roads that present no major challenges. Half of the path follows the Adour River and the hillsides of Chalosse. There is also a pretty segment along the Voie Verte greenway. Along the way, you can explore the Adour Valley and its old gravel pits, the Louts Valley, the baths in Préchacq-les-Bains and the hills of Poyanne.
