The Ciron is a left tributary of the Garonne, in Gironde, Southwest France.

Geography[edit]

The Ciron rises in the eastern end of the Moors of Gascony, in Landes. It flows north-west, mainly through the moors of Gironde, crosses the Sauternes vineyard and joins the Garonne at Barsac, downstream from Langon.

The moisture it brings, and morning mists it causes, are favorable to the development of Botrytis cinerea on grapes, a fungus that contributes to the high quality and renown of Sauternes wines.

Départements and towns[edit]

The Ciron flows through the following départements and towns:
