Atal Tunnel

Atal Tunnel is a historic engineering marvel and the world's longest highway tunnel above 10,000 feet, stretching an extraordinary 9.02 km through the Pir Panjal range to connect Manali with the remote Lahaul Valley year-round. Inaugurated in October 2020 and named after former Prime Minister Atal Bihari Vajpayee, the tunnel has transformed life in Lahaul and Spiti by ending months of winter isolation. Atal Tunnel Manali is a significant milestone in Himalayan infrastructure, revolutionising connectivity to Ladakh and Spiti while serving as a remarkable attraction in its own right for travellers on the Manali-Leh highway.
