The Engineering Wonder of the Himalayas

Before 2020, reaching Lahaul Valley required navigating the treacherous 51 km Rohtang Pass, taking anywhere from 4 to 6 hours and remaining closed for six months in winter. Today, the 9.02 km Atal Tunnel at 10,040 ft cuts travel time to just 15 minutes.

What to Expect on the Sissu Day Tour

Upon exiting the North Portal, the contrast is stark. The green cedar slopes of Manali give way to the rugged, towering mountains of Lahaul. Sissu village, situated 12 km from the north portal, features the roaring Sissu Waterfall, a natural willow forest lake, and adventure zip-lining.

Essential Travel Tips:

  • Best Timing: Start from Manali by 8:30 AM to beat traffic jams at Solang Valley.
  • Clothing: Wind speeds at North Portal and Sissu are high. Carry heavy windproof jackets even in May and June.
  • Permits: No special permit is required for personal or tourist cabs crossing Atal Tunnel into Sissu.
