Lahaul Spiti Valley

Nearly 50 years ago, IAF aircraft AN-12 flying from Chandigarh to Leh with 102 defence personnel mysteriously vanished in 1968.

Proposed in 1983 and launched in 2010, this 8.8 km tunnel is deemed the country’s longest. With only four metres left to be excavated in the middle of the tunnel, starting from Dhundi in Kullu district and ending at Gufa Hotel, near Sissu, in Lahaul-Spiti district, the tunnel is ‘almost on the brink of completion’ after a delay of over three years.
