A beautiful, fertile, flower-filled valley in Northern Nepal, Langtang locals make their living from tea houses dotted along a popular trekking route. For others, making a livelihood is backbreaking work; carting wood, growing potatoes and farming yaks. A yak cheese factory was built here by the Swiss in 1955 and ever since, a hard yak cheese has been cut from discs and carried two days to be sold in Kathmandu. In summer, yaks are taken to higher pastures for grazing, while in winter these hairy beasts remain under the traditional stone and wood houses keeping families warm. Resilient, resourceful and welcoming, the farming families of Langtang are the lifeblood of the valley but economically most at risk.
