I visited Kivach and Girvas today. It seemed to me that they are close, but as it turned out, Kivach is an hour's drive from Petrozavodsk, and Girvas is another 30 minutes from Kivach.
Their spillway usually occurs on the first of may or during repairs. By the way, you can get to Girvas without a ticket, if you drive a little further by car.
Then I went back and stopped in the center of shungit. I bought Souvenirs.
I looked at the time and realized that I don't have time to visit museums. In the end, I just walked along the embankment.
To be continued.
