The Sindhu Darshan festival is celebrated along the banks of the river Sindhu in Leh Ladakh region, every year on the full moon day. Celebrated over three days, this is a celebration of River Sindhu, the former Indus Valley Civilisation, with the motive of endorsing the river as an icon of communal harmony in India. The Bollywood movie "Dil Se" was shot at the first Sindhu Darshan Festival.
The first edition of the festival was held in 1996 during October. However, all the subsequent versions of the event have been held during June, to coincide with the full moon day, Guru Purnima.
