Lake Bol'shoye Rovkul'skoye
Lake Bolshoye Rovkulskoye lies among the forests and waters of western Karelia. It stretches from northwest to southeast, its four broad reaches joined by narrow straits. A channel connects it with the neighbouring Lake Rovkulskoye, while its waters drain through a chain of lakes and rivers toward Lake Pielinen. This is a landscape of intertwined waterways, with bays, islands and passages breaking up the outline of the lakes.
