* A tour of the paleovolcanoes is interesting and safe. We get acquainted with the hot past of Karelia directly at the scene of the events on the volcanoes Chertov Chair, Girvas and Konchezersky. The rocks, frozen two billion years ago, are overgrown with taiga. We will walk through forests and lake shores, guessing the directions of the lava outpouring. We will learn how to find and distinguish between granites and breccias, quartz and iron manifestations.
