The eastern-most portion of Brittany is only a two hour drive from Rouen. We headed into the clouds and drizzle of Brittany on Tuesday afternoon.
St-Malo
The town is known for its great sailors, but it is most famous for its corsairs, or pirates paid by the French royalty to pillage the British on the other side of the Channel during the 16th-19th centuries.

The ramparts of St-Malo. Viscount Rene de Chateaubriand is buried on the island in the background.

Alex, a cannon and a fort. To the left is the Fort National, a huge fortress and dungeon. You can't see them, but there were a couple of little boys waiting in line to take a picture with the cannon after Alex was done.

Walking down the ramparts.

Jacques Cartier is buried in the church of St-Vincent. Cartier is the explorer who discovered the St. Lawrence River and promptly drove a cross into the ground, claiming Canada for France.
Dinard
More clouds and drizzle as we headed towards Dinard, only 8 miles west of St-Malo along the Brittany coast.
Dinard has a promenade where you can walk along the coast. The rain started coming down a little too hard by the time we arrived, so we went to a creperie instead. Brittany is known for its crepes, so we had to try some. Delicious.
After the crepes, we drove from Dinard to Dinan for dinner and overnight. The road signs were a bit confusing: beware of the road signs between Dinard and Dinan. It's hard to remember which town you're headed toward (and which town you're in) when you see signs for both towns while driving in a roundabout.
Dinan
The next morning we woke up to a beautiful day. Sunny and not a cloud in the sky.
The viaduct on the outskirts of Dinan, spanning the Rance River. You can see part of the ramparts to the left.
View of the Rance River valley from aforementioned ramparts.
Dinard's streets are lined with artisanal studios and shops. The streets are also very steep. The buildings are very well preserved, so you feel like you're walking in medieval times (and at Medieval Times). There are also lots of shops that sell swords and suits of armor.

Rue de l'Apport and Place des Merciers. All of these streets are lined with 15-16th century houses.
