The trek to Neelkanth Mahadev Lake (4,200m ) is one of the most untouched treks in Lahaul & Spiti district of Himachal pradesh. Usually, the best time for this trek is in the month of Mid-June to Mid-September. Th nearest village from the trek's basecamp is Thirot and the total trek length is 15 kilometers one-way. Situated in Pattan Valley of Lahaul, Himachal Pradesh, the Neelkanth Mahadev Lake offers a splendid view of some of the tallest mountains in the region. While Neelkanth is a high peak in the Himalayan range dedicated to Lord Shiva, the lake is located at a height of 4,200m (13,777 ft) above mean sea level. There is also a small temple of Lord Shiva near this lake. As per local legends, this peak is also known as Neelkanth Kailash and many devotees from the country come here to take a dip in this holy lake.

The trek to Neelkanth Mahadev is a  really interesting trek with variable terrains throughout. The trek starts from Nainghar, a small hamlet with very little population which is located on the right bank of the glacial water stream flowing from mountains towards the Chandrabhaga river. Then the journey continues towards a beautiful small meadow located just in middle of the trek where we will meet the only people residing at such heights in these mountain ranges - the Shepherds, living along with their flock of sheep, whom they leave free for grazing in the region and the protector of the flock are alert, curious, and courageous mountain shepherd dogs. Then few glacial water streams with freezing cold water have to be crossed and finally, it comes to a stiff walk towards the end of the trek. This place is visited by those men who have failed to father a son. Women are prohibited by local people to visit this lake. The water of the Neelkanth lake is crystal clear blue in colour. A holy bath in this lake is regarded beneficial both for the mind and the body due to the presence of healing herbs in the water.
