The Atal Tunnel, also known as the Rohtang Tunnel, is an engineering marvel located under the Rohtang Pass in the eastern Pir Panjal range of the Himalayas. It connects Manali to the Lahaul and Spiti Valley, significantly reducing travel time and providing all-weather connectivity.

The tunnel is 9.02 kilometers (5.6 miles) long and stands at an altitude of 10,171 feet (3,100 meters), making it the world's longest highway tunnel above 10,000 feet.

The tunnel was inaugurated on October 3, 2020, and has since been celebrated for its contribution to improving accessibility and safety in the region. However, driving near the tunnel, especially during winter, can be hazardous due to icy roads and heavy snowfall. Travelers are advised to exercise caution and follow safety guidelines when navigating the area.
