Born from the glaciers of Mount Everest, the Dudh Koshi River is one of the most powerful and dynamic rivers in the Himalayas. Known as the “Restless River of Everest,” it carries glacier meltwater through steep mountain valleys, eventually joining larger river systems that flow across South Asia to the sea.

For centuries, this river has followed the rhythm of the seasons. Today, that rhythm is changing.

Rising global temperatures are accelerating glacier melt, altering river flow patterns, and increasing the risk of extreme flooding. These changes affect not only the mountain environments where the river begins, but also the millions of people downstream who depend on stable freshwater systems for survival.

The Dudh Koshi has become more than a river. It has become a visible indicator of environmental change.

Through the Summit to Sea expedition, this river becomes a pathway for understanding. By kayaking from the foothills of Everest and following the river’s full journey to the ocean, the expedition reveals the direct connection between climate change in the mountains and its consequences downstream.

This journey is not only about exploration. It is about observation, documentation, and responsibility.

By witnessing these changes firsthand, Summit to Sea aims to raise awareness about the importance of protecting fragile mountain ecosystems and the rivers they sustain. It highlights the urgent need for stewardship, respect, and action.

The story of the Dudh Koshi is the story of our changing planet.

From summit to sea, the message is clear: water connects us all, and its future depends on the choices we make today.
