Magical town with a fairytale castle. (however, I recommend you swerve the Logis Hotel-Restaurant du Chateau). Or if you can find no other accommodation, at least avoid eating in the restaurant, which was one of the few outright poor places to eat I've found in France.

It looks beautiful when you come along the bike path along the canal.

From this point, you have a superb view of the Josselin castle. There are opportunities for free and guided tours. The annual closure is from November 1 to April 8. The Castle dates from the beginning of the 11th century, when the nearby Viscount of Porhoët had a palisade built on this rocky promontory overlooking the Oust valley. In 1370, Olivier de Clisson, constable of France, had the fortress built.

The Château de Josselin is a two-faced building whose architectural details tell a thousand-year-old story. Standing on a rocky outcrop, it overlooks the Oust valley. On the river side, an austere facade evokes the feudal struggles of the Middle Ages. On the courtyard side, a more refined sculpted granite facade offers a particularly well-preserved example of Breton architecture from the end of the 15th century and the beginning of the 16th century.
