The term "Chadar" refers to a traditional blanket or sheet used in various cultures, particularly in South Asia. It is often made from wool or cotton and serves multiple purposes, including providing warmth and comfort. In some regions, it is also used as a decorative item in homes. In the context of trekking, "Chadar" is known as the frozen river trek in the Zanskar Valley of India.
