Red and white for the “GR” routes (long-distance footpaths), yellow for the local routes, and blue for the “PR” routes (walks)…
Return to the simple things in life, take your time, rediscover nature – walking is a special way of seeing a region. 
Aquitaine, with its variety of landscapes and contours, is particularly well-suited to walks.
Do the contrasting shades of autumnal forests appeal to you? The oaks and chestnut trees of Périgord will delight your artist’s eye.
Or do you prefer a mosaic of fields, valleys and orchards? Lot-et-Garonne awaits you with the famous Agen prunes to give you the energy you need.
In Gironde, the ocean waves aren’t the only things that are rolling. The vines are too! Did you know that the highest point in the Gironde is not the famous Dune du Pilat? It is at Samazeuil in the Bazas area, at an altitude of 166 metres.
To the south of the Bay of Arcachon, the Landes area is carpeted with maritime pine trees. In the Landes de Gascogne Regional Nature Park or among the villages of Tursan, walks will give you the opportunity to see a thousand and one natural and cultural riches.
Walks in the Pyrenees - Basque Country or Béarn – are obviously more strenuous. Those of you who dream of playing Indiana Jones might like to try crossing the Holzarté footbridge, in the Soule Valley.
A few figures: there are almost 6,000 km of sign-posted walking tracks in the Dordogne, 2,300 in Gironde, 2,000 in the Landes, more than 3,000 in Lot-et-Garonne and 5,000 in the Pyrénées-Atlantiques.
The local hiking committees publish some extremely useful walking guidebooks.
Logis de France have specific accommodation for walkers but more generally, overnight gîtes, chambres d’hôtes, campsites and hotels are all available for a good night’s sleep.
