The base camp of Siachen glacier, the world’s highest and coldest battlefield, was opened on Monday for domestic tourists on the occasion of World Tourism Day. The step has been taken to boost tourism in Ladakh and give people a window to appreciate the tough work done by army jawans and engineers in extreme weather and inhospitable terrains. Secretary Tourism, Ladakh, Mehboob Ali Khan, flagged-off a cleanliness drive from the tourist reception centre. The department of tourism, Leh, also organised a cleanliness drive along with various stakeholders of the tourism industry such as All Ladakh Tour Operators Association (ALTOA), All Ladakh Hotels and Guest Houses Association (ALHGHA), Ladakh Mountain Guide Association (LMGA) and others.
