Saint-Martin-sur-Oust

Tucked into the peaceful Oust river valley, this inland marina can berth over 280 boats on pontoons plus a dedicated 60-slip stopover area if you're just passing through. It's a quieter, more rural alternative to the busier coastal ports near Vannes, with the charming village of Saint-Martin-sur-Oust right on your doorstep for a stroll or a meal.
