L'Acheneau is a distinctive French river located in the Loire-Atlantique Department, within the picturesque Pays de la Loire region. Originating from the expansive Lac de Grand-Lieu, this left-bank tributary of the mighty Loire River flows for approximately 30 kilometers (18.5 miles) before joining the Loire near Le Pellerin. What makes L'Acheneau truly unique is its remarkably low elevation, averaging around 3 meters, which allows the tides from the Loire to occasionally reverse its flow, creating a fascinating bidirectional current.
