April to Mid-May
April marks the beginning of tourist season in Ladakh and the place starts to become alive with tourist activities. Restaurants open, hotels and guest houses get ready to welcome guest and various camps at sites such as Pangong Tso and Tso Moriri Lake commence to set up. Usually, by the second week of May, the crucial Srinagar-Leh highway opens up leading to a flurry of tourism energy into Ladakh.
By late April, all the lakes including the Pangong Tso and Tso Moriri begin to melt, uncovering the beautiful colors and fabulous sights.
