The regional tour of Brittany links the 45 sites that perpetuate the memory of Saint Columban and his Irish companions. 1700km long, it is divided into five parts, which can be followed successively or indistinctly. 
Starting at Saint-Coulomb, this first part leads inland to Blain, towards the southern limits of Brittany.
Alternating between coastal and inland routes, this great Celtic loop combines the traditional Tro Breizh, which links the towns of the seven founding saints of Brittany, with the more personalised Tro Breizh of Saint Columban - two pilgrimages in one.


With Saint Colomban, the route offers the opportunity to discover Brittany in all its diversity.

  1. St-Coulomb - Dol de Bretagne

  4. Lehon - Yvignac
