Program of the day: first we will discover the branch of Macau, located between the islands of the estuary and the Médoc wine region. We will stop over on the island Margaux to visit the winery and taste the wine produced on the island (Bordeaux supérieur). Then, depending of the tides, we will sail on the Garonne to the confluence with the Dordogne: where the Gironde estuary is born! During the navigation you can enjoy your picnic. To finish this beautiful day, we will stop in Bourg en Gironde and visit the lower town with a guide. We will return to Blaye along the picturesque Corniche road.
