The region of Saguenay lies in Québec by the huge Saint Lawrence River. It stretches across a fascinating glaciated landscape. Beluga and blue whales can often be seen at the mouth of the river. Further upstream, in the Parc du Saguenay, jagged cliffs loom up to 400 metres high around Baie Éternité. The source of the Saguenay River, the Lac Saint-Jean, is an almost perfectly round lake left behind at the end of the Ice Age and covering an area of 900 km2. It is a popular sailing area and holiday destination with beautiful beaches. The Saguenay region is also famous for its blueberries, which ripen in the woods in summer and which are the reason the locals are called "Bleuets".
