No tips, just enjoyed the solid Mairie building and the fine-looking bar-tabac nearby. Noyal-Pontivy is reached by some lovely, very quiet roads from Pontivy.

This greenway follows a tiny watercourse called the Hilvern Channel. When it comes to tranquility, it's hard to find better! 61.6 kilometers long and particularly tortuous, its two ends are only 21 kilometers apart as the crow flies.

This beautiful water town, famous for its Château des Rohans, is located in Argoat. That is to say in the very center of the Breton peninsula. It is a city which has preserved the Napoleonic memory of the great works carried out during the reign of the emperor. The Blavet is experiencing spectacular floods here which have left their mark on the inhabitants. The most recent ones date from January 1995 and February 2014.

Here, the Blavet meets the Nantes-Brest canal. It was Napoleon Bonaparte, then first consul, who decided on September 17, 1802 to channel the Blavet from Pontivy to Lorient. The project was titanic and lasted more than 30 years.

In addition to the Quelven chapel located in the town, the village of Guern has two other strong points: the very beautiful manor of Menorval and the proximity to the Sarre river. This very pretty watercourse tributary to the Blavet is still well preserved.

There are 28 locks which allow navigation between Pontivy and Hennebont. These structures, built in the 19th century, are still very important to the many pleasure boats that sail here. The lock keeper moves from one lock to another to allow boats to continue their journey in the Blavet valley.
