River rafting in Ladakh is quite unlike anywhere else in the world. It provides the best opportunity to enjoy and experience the natural beauty of the spectacular landscape with deep gorges, towering snow-capped peaks, hilltop monasteries, hillside villages, and glimpses of the unique wildlife. Ladakh offers a range of rafting options on the Indus and its major tributaries. The best stretch for professionally guided runs in white water is on the Indus between Spituk and Nimu or Saspol , which rates 2 to 3 in the international river grading scale of 1 to 6. Upstream of Spituk, the Indus has the easiest stretch up to Karu , which is ideal for basic training or "scenic floating". In recent years, running the Indus has become an attractive option to complement with sightseeing, and features on the itinerary of most visitors. Several travel agencies offer all-inclusive rafting packages. Ask for details at the Tourist Office at Leh. The most difficult but exciting rafting option is available on the Zanskar River , along its spectacular course through a gorge in the Zanskar Mountains , between Padum and Nimu . This is suitable only for well-organized white-water expeditions, prepared for about a week of rafting 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 arrangement for rescue back-up is an essential prerequisite for embarking upon this white-water expedition.
