I'd vote for the Manpupuner rock formations. They are recognized as a very popular attraction in Russia. The rock formations have been around for more than a million years. The Manpupuner rock formations or the Seven Strong Men Rock Formations have become a part of the Seven Wonders of Russia. I think the Seven Strong Men Rock Formations represent the stregth and endurance of our nation. They are exciting to see. As for me, they are the tops!
