At first it was an old pastoral practice done for thousands of years. It signifies seasonal movement of herds of cattle, sheep or goats from places good for grazing in the summer, with grasslands, and wintering sites, with milder winter climates. Now they are spectacular roads (like Transfăgărășan, Trans-alpina, Transrarău) in the mountains that allow us to go through in a pleasant way using transport and allowing us to feel a glimpse of the magic of those times.
