Rescuers have said that they fear many more people have died after being buried by landslides.
Around 100 tourists have already been flown out of the region, according to an army spokesman, who said much of the valley remains cut off to the outside world.
Thousands of people have been forced to leave their homes in Leh, the main town in Ladakh, due to mudslides. They fled to higher ground and had to sleep in the open air.
The main hospital in Leh was badly damaged, while use of the regional airport and communications links have been hampered the mudslides.
Soldiers and police are leading relief operations, with tourists and Buddhist monks who live in the area helping to clear areas.
Emergency medical centres have been set up and have had to cater for scores of injured people.
A police officer said that landslides had inundated Choglamsar, a village near Leh. Many residents are feared dead there.
Neighbouring Pakistan is also suffering flooding which has killed at least 1,600 people.
