European Waterways is opening up a part of France most travellers never see: inland Brittany. Aboard the hotel barge Nymphea, guests cruise deep into the region’s quiet interior, following the historic Canal de Nantes à Brest between Josselin and Redon. This is slow travel at its most rewarding — narrow waterways, lock-by-lock cruising and front-row access to medieval towns, market villages and unspoilt countryside shaped by Celtic history.
