The holy pilgrimage to the Manimahesh Lake (revered by local people as resting place of Lord Shiva) is supported by the Government of Himachal Pradesh, Manimahesh Pilgrimage Committee and several voluntary organizations. For the Gaddi tribal population of the region, pilgrimage to the lake is most holy. It is held every year during the Hindu month of Badon on Radha asthami, the 15th day following the festival of Janmashtami, corresponding to the Gregorian month of August or September. The Yatra or Jatra, as it is called, is also popularly known as the ‘Manimhesh Yatra’. It is heralded by a procession known locally as “holy chhari” (holy stick carried by the pilgrims on their shoulders) trek undertaken by pilgrims and sadhus. Pilgrims undertake the holy trek barefoot and cover a distance of 14 kilometres (8.7 mi) from the nearest road point of Hadsar to the Manimahesh Lake. Lord Shiva is the presiding deity of the yatra. The colourful procession of the “chhari” is accompanied by singing and recitation of hymns in praise of Lord Shiva. The Chhari trek, considered a tough trek, follows a set ancient route with stops at the designated places. To facilitate this trek, pilgrims are provided with facilities of transport (jeeps up to road ends), food and medical facilities and so forth. It is a two-day trek to the lake from Hadsar with a night halt at Dhanchho. Tents are available for hire at Bharmour or Chamba. Ponies are hired by some devotees for the trek. Direct trekking from Chamba is also an option undertaken by the devout, which is a nine-day trek; the route followed is Rakh (20 kilometres (12 mi)), Bharmaur, Hadsar (12 kilometres (7.5 mi)), Dhancho (7 kilometres (4.3 mi)) and Manimahesh (7.5 kilometres (4.7 mi)) with a brief halt at Bhiram Ghati. The return trip follows the same route.
The holy trek starts from the Laxmi Narayan temple and the Dashnami Akhara in Chamba town, with the sacred stick (‘Chhari’) of Gur Charpathnath carried by the pilgrims with participation of sadhus. The trek to the lake takes about 6 days. After the procession arrives at the lake, ceremonies are held all through the night. On the following day, pilgrims take a holy dip (naun) in the lake. After taking bath in the holy waters of the lake, pilgrims circumambulate the lake three times as an act of reverence, seeking blessings of the Lord Shiva. However, before taking a final dip in the Mani Mahesh Lake, women devotees take a dip at the Gauri Khund, which is situated about a mile short of the lake while men take bath at Shiv Karotri a part of the main lake. The belief is that Parvati, Shiva’s consort bathed at the Gauri Khund, while Shiva took his bath at the Shiv Kalotri. State priests of Bharmaur Brahmin family perform the worship (Pujas) in all temples within the lake precincts.
