This coastal and scenic road offers wonderful panoramic views with ever varying combinations of vines, water and stone, following the banks of Dordogne River. This is the Captains Route and their houses are still there, famous for their flowering gardens and the views out over the river towards the sea.
There are several small villages en route: the delightfully named Le Pain de Sucre (Sugar Loaf), Bayon, Marmisson, Gauriac and Roque de Thau, all have stunning panoramic views of the estuary.
Look out for the flowering gardens which flourish in the local microclimate, the troglodyte houses tucked away in niches in the cliffs, the fishing cabins with their traditional nets known as carrelets and the shipwreck which dates back to the second world war.
There are numerous picnic opportunities en route and the villages are worth exploring. The magnificent Chateau Tayac (with vineyards dating back to Gallo-Roman times) merits a detour, both for its wines and for the views out over the Bec d’Ambes (the point of confluence of the Garonne and the Dordogne).
The tourist office of Bourg offers an itinerary and audioguide which accompanies a game to be played en route. There are a series of windows looking out over the estuary, each one designed to offer a different view of the local flora and fauna.
