About Us



We are Nepal's leading adventure travel group.

We share our great experience of trekking and exploration of the mountains.


Thamserku was born in shadows of the mighty Everest, the dream of a Sherpa to share his passion for the mountains, nature and people of the beautiful Himalayas to the world.

25 years of steadfast experience in making lives adventurous and joyful has earned Thamserku a label as premier adventure travel company in the Himalayas and is respected all over the world. After a decade of expansion and working towards this goal, Thamserku now stands as the foremost company in Nepal to offer specialized travel and exploration services to more than 5000 clients each year in over 15 countries with it's specific strategic brands.

Though the expansion and growth has resulted in wider audiences, the story of Thamserku is still about family, a family of highly skilled individuals aiming to share their vision across borders. We also work in close alliance with our sister companies to provide a second to none all round services for travelers in Nepal.


The three brothers - Late Ang Tendi, Sonam, Ang Tshering.  The Story of Thamserku has always been about the family.



To support the growing trek and expedition business the brothers established Yeti Airlines. Ang Tshering shifted from Thamserku in 1998 to focus on developing the Yeti Airlines which is now nations biggest domestic airline company. 

Our Story

Our story begins with a couple’s passion – a passion for the greatest mountains in the world: the Himalaya. As guides and adventurers husband and wife team Sonam and Pasang Lamu Sherpa spent many years exploring the Himalaya’s magical valleys and ancient ways, setting the standards for mountaineering and climbing these magnificent peaks. The Sherpa people have traditionally been known as ‘the guardians of the Himalaya’

As Sherpa, we know and love this region and it is in this role that Sonam wished to share this knowledge and love with others. On his return from a season work in the French Alps, he knew he had to turn this journey of the imagination into a reality. In Sonam words “it was when standing on the summit of the 6,632m peak, Thamserku, that I decided to form a company that would offer everyone the opportunity to discover and appreciate the beauty and challenge of these awe inspiring mountains.” And so the Thamserku Company was born, establishing itself in a tiny office in central Kathmandu.

Our Values

The values of Thamserku are built on authenticity, trust, mutual respect and true partnerships that underpin our place in the global community:

He is currently the Managing Director of Thamserku Trekking, Executive Chairman of Yeti Airlines, and Managing Director of Yeti Mountain Home, deluxe mountain lodges in the Everest region, Nepal. His organizations have also earned several awards over the years and have grown exponentially. This comes as no surprise as Sonam's work is deeply seated in his passion and respect for the Himalayas and his relationship with the same: his late wife Pasang Lhamu Sherpa was the first Nepali woman to climb Everest in 1993, after which she lost her life on the mountain during the descent. As a former mountaineer, Sonam knows what mountaineers in Nepal want and as a son of the Himalayas; he knows what outsiders should not miss when they are here. It was after ascending Thamserku did he decide to start a company named after the mountain.
