La Rance Downwind Follow the Rance estuary south from La Richardais through the offshore turns toward the Mordreuc shoreline. The eight approximate points measure about 12.95 km, close to the source map's displayed roughly 12.6 km and the rounded 13 km listing. This is an image-based reconstruction, not an original GPS track; launch, landing and access are unverified. The accompanying photo shows boats in La Richardais harbour as local start-area context, not the full route. Check tidal flows, sluice operations, boat traffic and shore access before planning.
