Rohtang Tunnel

The Rohtang Tunnel, now officially known as the Atal Tunnel, is a strategic all-weather route connecting Manali to Lahaul & Spiti Valleys in Himachal Pradesh. At an altitude of 3,100 meters (10,171 feet) and spanning 8.8 km, it is India’s longest high-altitude road tunnel. The tunnel bypasses the treacherous Rohtang Pass (3,980 m), which remains snowbound for nearly four months every year.
