2. Crooked Forest (Krzywy Las), Poland

A spin through the Crooked Forest near Nowe Czarowo, Poland, will have you feeling off-balance. Planted in the former German province of Pomerania in 1930, the grove of around 400 pines has drawn crowds for over 80 years, proving to be one national forest to lose yourself in...and maybe be lost forever in a dream, as the melted trees make reality surreal. Though the forest’s β€œcrooked” look is likely formed by man, the technique by which it was formed and the reason remains a mystery.
