Among the most unusual forests in the world, there is one in Russia called the Dancing Forest as well as one in Poland called the Crooked Forest. They appear somewhat similar, containing an array of pine trees marked for their strange growth, and many similar legends and theories have arisen to explain this remarkable occurrence. They are twisted and swirling, forming curls and spirals — an extraordinary sight.Crooked Forest, Poland.
