A small town on way to Yumthang, it stands at the confluence of the rivers Lachen chu and Lachung chu. The North Sikkim highway bifurcates from here with one road leading to Lachen and the other to Lachung. Chungthang valley is considered to be a holy place which has been blessed by Guru Padmasambhava, the patron saint of Sikkim. There is a rock here which to this day bears the hand and footprints of Padmasambhava. From a small opening in the rock there is continuous flow of mineral water. There is a small patch of land here from which grows paddy every year. The nature defying miracle is believed to be the blessing of Guru Padmasambhava who sprinkled a handful of grain on the spot which has sprouted paddy ever since.

Chungthang is a good place to halt before one takes off for the more alpine regions of Lachen, Lachung and the Yumthang Valley. Chungthang is mired in myths and legends, one such being that this is the place from where the word ‘Demazong’ [the hidden valley of rice, as Sikkim is known first originated.


The picturesque mountain village of Lachung, at a height of 8610 ft, embraced by snow capped mountain peaks, breathtaking waterfalls, sparkling streams and apple orchards is the perfect holiday destination.

The area is restricted for foreigners, but special passes can be procured in advance. A few lodges are available here for stay as well as Forest Department and a PWD Bungalows.


As per Denjong Nye-Yig (The Pilgrim's Guide to The Hidden Land of Sikkim, by Jigme Pawo, reincarnation of Gyalwa Lhatsun Chenpo) and Nay-Sol texts, Gurudongmar Lake, located at an altitude of about 17,000 feet within the Lachen Dzomsa area in North District, Sikkim, is one of the 108 "Tso-Chen" or major holy lakes of Denjong (Sikkim) which are believed to be abodes of local guardian deities. The holy lake is located close to Mt. Khangchen Gyao, also considered sacred by the locals.
During the eight century AD, Guru Padmasambhava, also referred to by Buddhists as Guru Rinpoche, hailing from the Swat region in present-day northwest Pakistan, visited Tibet at the invitation of the Tibetan emperor Trisong Deutsen and introduced the practice of Tantric Buddhism to the Tibetans.
On his way back from Tibet, Guru Rinpoche is believed to have visited Sikkim and Gurudongmar Lake was probably the first major landmark that the Guru came across upon his entry into the fabled hidden land of "Denjong"/"Demojong". The word "Dongmar Shab Chakpa" refers to his visit to this place. He recognised the lake as a part of Dorje Nyima/Chorten Nyima, a sacred place of worship in northern Sikkim.
It is believed that the Guru, in order to provide drinking water to the local people during winter when the lake freezes, placed his hands on a part of the lake, which miraculously stopped freezing during winter, thereby facilitating in provision of drinking water to the locals. Since then, the water of the lake is considered sacred.
Recognising the auspicious omens in the lake, Guru Rinpoche saw them as propitious and favourable signs welcoming his entry into the land of Denjong/Demojong.
Devotees believe that by offering prayers at the holy lake, one can be blessed with the birth of a child/children.

Monasteries of Tsunthang Sub-Division-

  • Ridgzing Choeling Gonpa (monastery), Tsunthang:
    The historic and religiously significant Ridgzing Choeling Gonpa (monastery), located at Tsunthang, is one of the oldest monasteries in Denjong/Sikkim, belonging to the Nyingmapa Sect of Tibetan/Himalayan Buddhism. It is believed that Guru Rinpoche (Guru Padmasambhava) himself consecrated the site on which the Gonpa stands. The original monastery structure was built around 1788 AD by local Lepcha Buddhists.
    The later day structure, that stood on the very site where the original monastery once stood, was built during the reign of the twelfth Denjong Chogyal, Miwang Palden Thondup Namgyal in 1968. This structure was unfortunately severely damaged by the September 18, 2011 earthquake that devastated many parts of Sikkim.
    Presently, a new monastery structure along-with a new Mani Lhakhang, are coming up at the site.
  • Samten Choeling Gonpa, Lachung:
    The Samten Choeling Gonpa, located at Lachung, was built around 1850 AD.
    The Gonpa, which is one of the most important in Denjong/Sikkim, originally adhered to the Bon Sect of Tibetan/Himalayan Buddhism. However, it was subsequently affiliated to the Nyingmapa Sect. The copper idols of the Buddha, Guru Rinpoche and Chenrezig (Avalokitesvara) as well as the holy Kangyur and Tengyur religious texts, that the monastery possesses, were brought from Tibet.
    The present Samten Choeling Gonpa structure underwent renovation and remodelling in 1983.
  • Ngodup Choeling Gonpa, Lachen:
    The Lachen 'Ngodup Choeling Gonpa' was built around 1858 AD, by Karchen Dorje Drak, a monk who hailed from Tibet. However, it was during the lifetime of Ngawang Kunzang Rinchen, also known as Lachen Gomchen, that the monastery acquired prominence. The Rinpoche, who hailed from Namok village in north Sikkim, was persuaded by the ninth Denjong Chogyal, Miwang Thutob Namgyal and local Lachenpas to stay on at Ngodup Choeling Gonpa.
    The monastery, which possesses a number of religious artefacts, is a significant Nyingmapa monastery of Sikkim.
  • Kunzang Choeling Gonpa, Ship-Gyer:
    The Ship-Gyer Gonpa, initially built around 1900 AD, was later on rebuilt in the year 1985. It adheres to the Nyingmapa Buddhist tradition. HE Dodrubchen Rinpoche consecrated the new monastery structure and named it as 'Kunzang Choeling'. Located at a distance, above the monastery site, is a lake known as 'Lamtar Tso', which is considered sacred. Near the lake is a site called 'Shemu Mungda', where Guru Rinpoche (Guru Padmasambhava) is believed to have slain a Shemu (demoness). There is also a place where the Guru is believed to have tied his horse and a stone where it is said he placed his hat. It is also said that, at this site, the Guru opened a 'Naygo' or 'a door to a sacred place', where holy water (Dubchu) is still found, even to this today.
  • Ugen Samdroling Gonpa, Naga:
    The Ugen Samdroling Gonpa of Naga, which follows the Nyingmapa tradition of Tibetan/Himalayan Buddhism, was established in the year 1937.
    The Gonpa was built by local Buddhists on the direction of Kyabgon Batrul Rinpoche, an eminent monk who visited the place while on a visit to north Sikkim.
    Currently, a new and much larger monastery structure is being built at the place. There is also a Mani Lhakhang on the campus.
    'Chaam' or religious dances are held here, participated in by local monks, in the month of December each year.
  • Samten Choeling Gonpa, Thangu:
    The Samten Choeling Gonpa of Thangu, which is a branch of Lachen Ngodup Choeling Gonpa, was formerly a hermitage founded in the 19th century by a Buddhist monk from Kham in Tibet. Subsequently, around 1974, a small Lhakhang (temple) was built at the site by local Lachenpas.
    In 2003, with State Government assistance, the present monastery structure was built.
    During the summer months, the people of Lachen move to Thangu, which is located at an altitude higher than that of Lachen. Here, they practise cultivation of various varieties of vegetables such as potato, radish, cabbage etc. The religious occasions that fall within these months, are performed at the Thangu monastery. During the winter, the public fall back to Lachen.
