Ladakh is a land abounding in awesome physical features, set in an enormous and spectacular environment. Bounded by two of the world's mightiest mountain ranges, the Karakoram in the north and the Great Himalaya in the south, it is traversed by two other parallel chains, the Ladakh Range and the Zanskar Range.

Today a high-altitude desert, sheltered from the rain-bearing clouds of the Indian monsoon by the barrier of the Great Himalaya, Ladakh was once covered by an extensive lake system, the vestiges of which still exist on its south-east plateaux of Rupshu and Chushul, in the drainage basins or lakes of Tso-moriri, Tso-kar and Pangong-tso. But the main source of water is winter snowfall.
