A range of rafting options is available on the Indus and its major tributaries. The best stretch for professionally guided runs in white water is on the Indus between Spituk and Saspol. Beyond Saspol, the river becomes difficult and funning it requires technically skilled participants and careful organization. Upward of Spituk, the Indus has the easiest stretch up to Karu, ideal for basic training and for day-return "scenic floating" for amateurs. In recent years, running the Indus has become an attractive alternative to trekking and features on the itinerary of most visitors. The most difficult but exciting option for river running is on the Zanskar along its spectacular course through the gorge in the Zanskar mountains, between Padum and Nimo. This is suitable only for well organized white-water expedition, prepared for several days of river running and camping in absolute wilderness. Participants are required to be trained rafters themselves while the arrangements should be assigned to a dependable professional agency. Adequate arrangements for rescue coverage are an essential pre-requisite for embarking upon a white -water expedition on river like the Zanskar.
