Updated on October 16, 2025

Kyimolung, which means "Hidden Valley of Happiness," lies in the sacred Tsum Nubri area of Manaslu, which is in Nepal. The Buddhist scriptures say that it is one of the eight most sacred hidden areas (Behyul), and it is very important to the spiritual, cultural, and historical world. The idea of Behyul is a holy location where people who are looking for peace and safety might find it during times of war and sadness, as Guru Padmasambhava (Guru Rinpoche) said in the 8th century.

This sacred site, situated between Mt. Manaslu (8,163m) and Mt. Kailash, symbolizes tranquility, purity, and nonviolence.  About a hundred years ago, the Tsum and Nubri Valleys were formally declared an Ahimsa (non-violence) zone. This is the administrative area that contains both valleys. This kept its natural beauty and spiritual history safe. The valleys in the Himalayas are a sign of benevolence since they don't let people murder animals, and they encourage people and animals to live together.

Kyimolung is home to many old monasteries, meditation caves, and pilgrimage sites that are closely tied to Buddhism.   Some of the most sacred places include Serang Gumba, Naksa Chyoiling, Tashi Chyoiling,Tong Gumba, and Sadul Chyoiling Monastery.   Each one has a lengthy history and is embellished with gorgeous murals, rare manuscripts, and relics of Guru Padmasambhava.

Serang Gumba, which is at the base of Mount Shringi (Tashi Palsang), is thought to be the center of Kyimolung. More than 100 monks and students live there and obtain free spiritual and academic teaching. People flock there to meditate in caves, drink from holy springs, and see relics that are thought to have been blessed by Guru Rinpoche.

The Naksa Chyoiling Monastery is one of the oldest in Nepal; it was built about 1,200 years ago.  There are a number of old Buddhist monuments, scriptures, and art that the monks made themselves.  There are gorgeous mountains and animals all around the monastery.

Tashi Chyoiling, Tong Gumba, and Sadul Chyoiling are other busy spiritual centers where pujas, annual rituals, and traditional Cham dances keep alive Buddhist customs that have been there for hundreds of years.

Kyimolung is a great example of how culture and nature can work together. It also has a spiritual element. The monasteries are in the heart of alpine meadows, woods, and rivers where animals like Himalayan blue sheep and pheasants can roam free.   The monks' rhythmic chanting, the prayer flags billowing in the wind, and the calm Himalayas in the background all make for a tranquil and illuminating place.

From ancient times, the VAST, MYSTERIOUS, and spectacular four (KYIMOLUNG, Dhemajung, Pemaque, and Khempalung) hidden lands (Behyul) stretched from the eastern Kanchenjunga to the western Api Mountains, are considered the world's most sacred, austere, and holy land carrying religious, spiritual, cultural, and historical significance.  

Almost the world's 108 hidden lands, 8 are mentioned in the Buddhist scriptures in great scriptures in great grandeur and detail. Among the world's tallest peaks above 8000 meters, Nepal is home to eight peaks, of which Manaslu (8,163m) is second to Sagarmatha in terms of lively trekking routes. Tsum Nubri is nestled between Mamaslu and Mt. Kailash, regarded as the cradle of ancient civilization. This region is renowned worldwide as synonymous with a place of purity, beauty, peace, and nonviolence. 

The meaning of Behyul refers to a hidden sanctuary. About 100 years ago, at the special request of the Bhutanese religious leader Guru Lama Dukpa Rinpoche, during the reign of King Girvan Yuddha Bikram ShahDynasty, Chumnubri was officially declared an Ahimsa zone (sacred zone).  As a result, the Chumbubri valley has become a beacon of non-violence, spreading the message of peace across the world with pride. 

To strengthen this Shakya law has also been implemented with the consent and cooperation of the local community.

Among the 7 wades in the Chumbubri Rural Municipality, Wada number 3, where the center head office of local government is established, is inhabited by the Gurung ethnic group remaining while the remaining 6 wades are Lama Community. After crossing the Chumbubri Rural Municipality center office at Philim village, the right-hand side valley called “Tsum valley” and the left valley along the Budhigandaki river basin known as “Nupri Valley”. Both valleys are fertile land of Buddhism. According to the local rule, it is not allowed to kill or sacrifice animals in those valleys.

Due to its religious significance, Chumnubri was declared an Ahimsa (non-violence) zone, and the surrounding areas of the monasteries are preserved as sanctuaries for hundreds of species of animals and birds.

In the 8th century, the great Dharma King Trishing Detsen invited the revered Guru Padmasambhava to Tibet for the preservation, promotion, and propagation of the Dharma. With deep concern, the king asked, 
"In the future, when the world is filled with war, conflict, and hardship, will there be any safe refuge where people can go in order to practice?"

 In response, Guru Padmasambhava emphasized the significance of Kyimolung, saying, 

"O Dharma King! There will be five sacred valleys where war shall never enter: Sambu Lung, Jonpa Lung, Ribtsng Lung, Phakri Lung, and Kyimo Lung."  
Behyul Kyimolung is renowned in the human realm as a sacred pilgrimage site of the great Guru Padmasambhava (from the 8th century). Known locally as “Nubri”, referred to in ancient Buddhist texts as “Behyul Kyimolung”, and described in English as the "Hidden Valley of Happiness," this valley has been connected to Buddhism. It was identified by Guru Padmsambhava (Guru Rinpoche) over a millennium ago and is widely known as the alley of countless monasteries.

As part of the annual program of the Government of Nepal, the Buddhist Philosophy Promotion and Monastery Development committtee has produced the documentary with the motive of uncovering the historical and archaeological significance of places that, despite being renowned for their historical, religious, spiritual, natural, and cultural heritage, have remained in obscurity due to a lack of publicity. Here we are going to highlight sacred sites, including Naksa Chyoiling Monastery, Tong Monastery, Sadul Chyoiling Monastery,Tashi Chyoiling Monastery, and the Kyimolung region, envisioned as future religious tourism destinations located in the Chumnubri Rural Municipality of Gorkha District

Another significant destination in Nubri Valley is the heart of Kyimolung, Serang Gumba. Nestled in the lap of Mount Shringi, also known as Tashi Palsang, the journey to Serang Monastery begins from Bihi village. The integrated settlement, monasteries, and ancient Stupas of Bihi village reflect its religious, cultural, and social identity. Walking along the old settlement, the mountain paths, and the bank of the Shringi River, and traversing through a narrow yet safe mountain trail, one reaches the entrance of Serang Monastery

Serang Gumba Manalsu

Near the entrance, the sacred Khandosangphuk can be observed, where Guru Rinpoche is believed to have created a water source for the well-being of female deities. The belief is that drinking the nectar-like water Jhandosangphuk brings peace, happiness, and longevity. A few minutes' walk from Khandosangphuk takes one to Bukhur. Around Bukhur, numerous Neh (meditation caves) can be found. 

There is a religious belief that Guru Padmasambhava meditated in Bukhur in the 8th century BCE. Today, monks from various traditions continue the in broken practice of meditation and chanting in these caves during the occasion of Duchen. Near Bukhur is the Sambel cave, where a sacred self-originating Bumpa (vessel) can be seen. It is believed that Guru Padmasambhava created a water source from the Bumpa. Monks still follow the tradition of filling this water into their sacred vessels for the Wang (long-life blessings) ritual.

After a short trek, one reaches the base of Tashi Palsang Himal. This land, imbued with spiritual significance, is regarded as a divine realm. It is believed that Guru Padmasambhava meditated here for a long time, concealing countless treasures. According to the belief, treasures hidden by Guru Padmadambhava in the Behyuls of Tibet, Nepal, and Bhutan are seen as rare, indestructible, and indivisible, meant for future generations. The great masters who have meditated here are thought to have nurtured this land, which is considered immensely sacred, where peace, prosperity, fame, happiness, and liberation for humankind can be attained. The land is known as Kyimolung, or the "Sacred Land of eternal Wisdom."

Serang Gumba Manalsu Gorkha

On the other side of Serang Gumba, in the divine realm of Behyul, local belief holds that invaluable treasures, hidden meditation caves, and concealed Neh (meditation spots) exist. 

It is believed that the water flowing from the Khando Dbchyu, produced by Guru Padmasambhava, is considered sacred and is accepted as nectar, bringing purification and blessings to those who drink it. 

The great Yogi and tantric master, Guru Padmasambhava, is believed to have attained wisdom, meditation, and blessings for his disciples on the path of spiritual knowledge and spread the practices across the Himalayan regions of present-day Nepal and Bhutan.
