This section of the GR10 takes you to the heart of the Pyrenees. It crosses the Pyrenees from Cauterets to Bagnères-de-Luchon and can be described in two parts.
The first part of the itinerary takes place in Pays Toy. The word ‘Toy', formerly Thôys, means : child or small and refers to the youthfulness of the villages.
