Highway tunnel & Lahaul village · 3,100 m

Atal Tunnel & Sissu

The Atal Tunnel runs 9.02 km under the Rohtang ridge and connects Manali to the Lahaul valley in about ten minutes. It has quietly become the single most important thing to happen to Manali winter tourism, because it made Lahaul reachable in the months when Rohtang Pass is shut.

Before the tunnel opened in October 2020, Lahaul was cut off from Manali for roughly six months a year. Now you drive under the mountain and come out at the north portal into a completely different landscape — drier, starker, more Tibetan than Himachali.

Sissu is the first proper village on the far side, sitting beside the Chandra river with a waterfall dropping off the cliff behind it and a small frozen lake in winter. For most travellers this is where the trip's best photographs happen: the Manali side can be slushy and crowded while Sissu is still clean, deep snow.

What's actually there

  • The tunnel itself — 9.02 km, one of the world's longest highway tunnels above 3,000 m
  • Sissu waterfall, frozen into a column in deep winter
  • Sissu lake and the helipad ground, the valley's best open snow field
  • Views across the Chandra river to the Lahaul ranges
  • Dhaba stops on the Lahaul side for thukpa and hot chai

Local notes

  • Photography is not allowed inside the tunnel and stopping is prohibited. Do the photos at Sissu.
  • The temperature drop between the two portals is real. Carry the jacket even if Manali felt mild.
  • Check the morning road status in heavy snow — the tunnel can be closed for clearing at short notice.
  • Sissu is at 3,100 m. If you came from sea level yesterday, take the first hour slowly.

Atal Tunnel & Sissu — common questions

How long is the Atal Tunnel?

9.02 km. It runs beneath the Rohtang ridge and takes about ten minutes to drive, cutting roughly 46 km off the old Manali–Lahaul road.

Do I need a permit to cross the Atal Tunnel?

No permit is needed for the tunnel or for Sissu and Keylong. Permits apply to Rohtang Pass, which is a different, higher road.

Is Sissu open in winter?

Yes, and that is the point of the tunnel. Sissu stays reachable through most of the winter, which is why it has replaced Rohtang as the standard winter snow trip.
