Dudh Kosi River is in eastern Nepal and known for its highest elevation. Sapta Koshi or Kosi River irrigates eastern Nepal. Seven rivers join in eastern Nepal owing to which it is called Sapta river also. This ravine actually originates from Mt. Everest, where glaciers and snowmelt contribute significantly in making appropriate streamflow.

Dudh Kosi River features extreme white water and is generally not used for water sports. Due to this, Dudh Kosi also means Milk River. There are sudden and steep turns that need to be port-gated. Big stones seem moving by the natural forces.

When the river due to its altitude came under the observation of successful Austrian paddlers, they made a team of 16 members and sat on a journey from Dehylov by cars. The Dudh Kosi River trip began in April 1973 near Pheriche and continued down the river for 126 Km. The expedition remained successful. Since then there have been many paddler expeditions using a wide variety of boats. And for the kind of paddler tourists, it is among the best places available in the world.

Things that must be kept in mind by the tourists are that does not go without a guide in the Everest region and your fitness must be good. Try to acclimatize gradually but definitely, however, return if the health does not allow. A BBC documentary released in 1977 named Dudh Kosi: Relentless River of Everest might help in preparing you for the journey of the Dudh Kosi River.
