Between Gauriac and Bourg, the corniche road runs along the Gironde estuary sometimes at the foot sometimes at the top of the cliff. Many troglodyte houses dot the landscape. You can see them from the road or walk past them on the hiking trails, but you can't visit them: some are still inhabited! This picturesque road is also nicknamed the flowered cornice or the road of the captains. During your walk you can admire the beautiful houses built by the old seafarers who brought back from their travels exotic species still visible in the gardens. This 10km course is punctuated by explanatory panels called windows on the estuary: the tidal bore, the islands, the fish, the wrecks... all the stories will be revealed to you. You can also see the squares up close and rent one!

Your itinerary



The town is home to the charming port of Roque de Thau, the starting point of the Route de la Corniche. It is here that you can hire a plaice and climb the wooden boom that juts out over the estuary.


On the pretty Route de la Corniche, Gauriac dominates the waters of the Gironde estuary. Don't miss the troglodyte habitats nestled in the hollow of the cliffs, the wreckage of boats and the picnic tables.

Bayon sur Gironde

It is besides in front of Bayon that the estuary created by the reunification of the Dordogne and the Garonne is born. The most remarkable cultural point of this peaceful village is undoubtedly its church, which has a long history. Don't miss its bell tower surmounted by a virgin. On my terrace at Château Eyquem, a panel explains the creation of the estuary and the tidal bore.

Pain de sucre

The corniche road continues and meanders between gardens with tropical species and Bourg stone houses which recall the historic past of the corniche road with its long-distance captains, its boatswains and its quarrymen.


The village of Bourg is an old medieval village whose upper town hosts the shops of artists and craftsmen and the lower town is occupied by the port and offers a magnificent view of the old ramparts.
