In the Heart of Franche-Comté

Cruise through this atmospheric 681-meter tunnel carved into the rock,a unique river experience.

From your boat, take in postcard views of Ray-sur-Saône, with its fortified medieval castle and typical Comtois church nestled in greenery.

The main attraction in Savoyeux is best experienced from the deck of your boat: a 10-minute cruise through the 643-meter-long canal tunnel, carved into the rock.

As the Saône widens, Gray unfolds with its stone quays and rich port legacy. Don't miss the Renaissance Town Hall, 15th‑c Basilica, Italian-style theater, Baron Martin Museum in the château, and the Museum of Art & Archeology.

Near the river stop, relax at a shaded picnic area. For a scenic lunch, visit Lamugnière Park with greenhouses and exotic trees: ginkgo, weeping beech, Atlas cedar, and Chinese mahogany.

Art and history enthusiasts can admire one of Haute‑Saône's finest altarpieces in the 17th‑century Saint‑Maurice Church, a listed monument.

At the Velet riverside stop, a small unsupervised beach allows for swimming in the Saône. It's suitable for children thanks to the shallow water over a large area.

A pleasant stop on the Petite Saône, Mantoche delights visitors with its elegant merchants’ houses, its 18th-century rebuilt church, and its château.

A former Burgundian stronghold on the Comtois bank of the Saône River, Auxonne boasts rare military heritage. The Bonaparte Museum, housed in Louis XI’s château, features the room where Napoleon trained as an artillery officer. The Vauban arsenal, now a market hall, is another highlight. Dock your license-free boat to explore the city on foot and admire its fortifications, the Comté Gate, the Royal Gate, and the 13th-century Notre-Dame Church.
