Part of a brilliant 2 book set of maps covering the Way of St James at a scale of 1:150,000 (1 cm = 1.5kms)
The first book the Chemins de Compostelle covers from Le Puy-en-Velay to Saint Jean Pied de Port
The second book Camino de Santiago covers from Saint Jean Pied de Port to Santiago de Compostela.
Each book includes topographic maps, altitude profiles for each leg of the walk, place name index, & maps of key towns.
I have done 200kms of the Chemin and can guarantee that these books are great not just for planning but also for use along the way, and at only 20cms x 11 cms they easily fit in your day pack.
