Cancale's oyster farms are among the most famous oyster-farming areas in France. Thanks to the nutrient-rich waters and strong tides, the conditions here are ideal for farming. Several thousand tons of oysters are produced annually on approximately 400 hectares – primarily the Pacific oyster (Crassostrea gigas) and the flat oyster (Ostrea edulis). The oysters mature in metal racks or bags exposed at low tide, allowing farmers to regularly turn and care for them. Oyster farming has been part of Cancale's identity for centuries and was recognized by UNESCO as an intangible cultural heritage of France in 2019. Visitors can tour the farms, for example at the Ferme Marine de Cancale (https://www.ferme-marine.com/de/), where they can learn about the farmers' work and taste fresh oysters firsthand.

Dol-de-Bretagne is a historic town founded as a bishopric in the 5th or 6th century under the influence of Saint Samson of Dol. The town is known for its well-preserved medieval architecture, including the Saint-Samson Cathedral, the Musée de la Trésorerie, and the Maison des Petits Palets. The surrounding area also features the Menhir du Champ-Dolent, a megalith dating back to the Neolithic period that is over 4,000 years old. Markets, local festivals, and small shops enliven town life, and despite its touristic significance, the town remains relatively quiet and manageable, an ideal place to experience history, culture, and Breton flair.

Going back up towards St-Malo, a pretty path to the left (Rance valley) allows you to partly avoid the D117.

The dam trail is great for riding, but be careful, there are rocks on the way down. My tire was completely flat afterward.
