The Rance is a river of mysterious origins that once knew the formidable power of the spring tides but is now harnessed by a tidal power station (left bank). The estuary is a superb stretch of water whose banks are rich with a varied heritage, full of history and legend, that it is worth taking the time to discover. The river is negotiable by boat between St Malo and Dinan. Don't miss Saint Suliac, a lovely fishing village (right bank), or the Jardins du Montmarin, gardens which afford wonderful views over the Rance River.
