The Chadar Trek or the frozen river trek is different in the slow gain that it takes in altitude, spread evenly throughout, and takes you to a maximum height of 11,800 ft, deep in the Himalayas! The experience starts at Leh, crosses the frozen Zanskar, and reaches the Ladakh town of Chilling, the actual starting point of the trek from where the frozen river trek starts. The total distance covered during the Chadar trek is a 62 km, spread evenly throughout the 6 days of the trek that you undertake on foot. The Chadar trek is only open in the months of January and February, as these are the only times when the emerald, flowing Zanskar river is frozen enough to enable trekking on it.
