- Fancy a real adventure trek with breathtaking views? The Chadar Frozen River Trek is your best bet. This trek covers a staggering 105 km one-way, with an average of 15-17 km per day. The winter snowfall closes most mountain passes and the ‘Chadar,’ meaning blanket refers to the frozen Zanskar river which becomes the only way for the residents near Zanskar to connect with the rest of the world. At times, the temperature drops to -30 to -35 degree Celsius. Despite the freezing temperatures, the sun and the blue skies are up by 9:00 am and that’s when our daily stay begins. While most of the trekking will be done on the frozen river, chadar or the normal trail used by the people in Zanskar, sometimes we will climb icy rocks or trails.
