Atal Tunnel, Manali: The 9.02 km Gateway to Lahaul and Spiti

The short version

• 25 km about 25 km (24.1 km on NH 3) from Manali to the South Portal, roughly a 55-minute drive.

• No toll: free to drive through. There is no toll or ticket for the tunnel itself.

• No permit: no permit needed, unlike Rohtang Pass. You can just drive up.

• Best time: go Dec to March for snow at Sissu, or May to October for green Lahaul and onward roads to Spiti and Leh.

• Why it matters: it shaves about 46 km and four-plus hours off the old Manali to Keylong and Leh route.

About Atal Tunnel: what it is and why it matters

Atal Tunnel is in Himachal Pradesh, just north of Manali, and it joins two valleys that the Pir Panjal range had kept apart for most of the year. The South Portal opens near Dhundi in the Kullu/Manali valley. The North Portal comes out at Sissu in Lahaul, on the banks of the Chandra river. Locals and older maps still call it the Rohtang Tunnel, its name before it was dedicated to former Prime Minister Atal Bihari Vajpayee.

The engineering is the headline. At 9.02 km it holds the record for the longest highway single-tube tunnel above 10,000 ft, and it was carved under the Rohtang massif so traffic no longer has to climb the pass at all. That is the practical point for a traveller. The old road over Rohtang was a four to five hour ordeal of switchbacks and traffic jams, shut by snow through winter. The tunnel does the same crossing in about ten minutes, stays open through the year, and has effectively put Sissu, Keylong and the roads to Spiti and Leh within day-trip and weekend reach of Manali.

It runs along NH 3. Inside, it is a modern, well-lit, single-tube two-lane road with a fireproof escape tunnel running beneath the main carriageway, CCTV along its length, and emergency call points at regular intervals. You drive straight through. There is no viewpoint or parking inside, and stopping is not allowed.

Atal Tunnel or Rohtang Pass: which do you actually need?

This is the question most first-timers get wrong, because the two are close together but do completely different jobs. The tunnel is the route. Rohtang Pass is the snow-point experience above it. Here is the honest split.

Most people doing Sissu or a Spiti/Leh trip only need the tunnel. If snow play and the classic pass viewpoint are the goal, you want Rohtang Pass, and you will need to book the permit in advance. Many travellers do both in one trip: the tunnel on the way to Lahaul, Rohtang as a separate half-day.

How to reach Atal Tunnel from Manali

The drive is short and scenic and follows NH 3 north out of Manali through Palchan and Solang. From Manali town it is about 25 km to the South Portal, close to an hour depending on traffic near Solang. You do not go over Rohtang; the tunnel branches off below it.

By taxi or self-drive

A local taxi from Manali to Atal Tunnel and Sissu and back is the most common way to do it, and drivers know the road and the barrier stops. Self-drive is straightforward in summer; in winter you want experience with snow and, ideally, chains, because the approach above Solang ices over.

By bike

The tunnel is a bucket-list ride, and Royal Enfields are easy to rent in Manali. It gets genuinely cold inside even in summer, so carry a windproof layer for the crossing.

By bus

HRTC buses running from Manali towards Keylong and Kaza pass through the tunnel and will drop you at Sissu. This is the budget option, though timings are limited and seats fill fast in season.

For the full onward journey, see our Manali to Leh road trip guide.

Distance from Atal Tunnel to key points

The one table people actually come for. Distances are by road; drive times assume clear conditions.

The tunnel is why the Manali to Keylong and Leh run is so much faster than it used to be. It removed the Rohtang climb entirely and, on the Leh route, cut about 46 km and more than four hours from the old road.

Timings, rules inside the tunnel and best time to visit

Atal Tunnel is open 24 hours a day, all year. In heavy snow the portals can shut for short spells while BRO clears the approach, so in deep winter check the road status before a very early start. There is no ticket window and no fixed 'visiting hours'. You simply drive through whenever the road is open.

Rules inside the tunnel

• No stopping: stopping, parking and getting out for photos are not allowed inside. Keep moving.

• Speed limit: observe the posted limit (around 40 km/h for the tunnel; confirm on the signs). Speed cameras are active.

• Stay in lane: lane discipline is enforced and overtaking is prohibited inside the tube.

Do your photography at the South Portal approach or, better, at Sissu just beyond the North Portal, where there is a waterfall, a lake and open meadows to stop at.

Best time to visit

For fresh snow around Sissu and the north portal, come between December and March. This is when the tunnel is at its most dramatic and Lahaul turns white, though you should carry chains and watch road status. For green Lahaul, waterfalls in flow, and open onward roads to Spiti and Leh, come between May and October. The high passes beyond Keylong (Baralacha La on the way to Leh, Kunzum on the way to Spiti) only open around June.

Toll, green tax and permit rules

There is a lot of confused information online about this, so here is the clean version. Driving through Atal Tunnel is free. There is no toll booth and no ticket for the tunnel itself. What you may pay are two separate local charges on the route, and they are not tunnel tolls.

What you actually pay

So if you drive from Manali to Sissu and back, the only levy specific to the crossing is the small SADA entry tax collected at Sissu when you enter the Lahaul-Spiti area. The tunnel adds nothing. Rates are revised from time to time, so treat the figures above as a guide and keep some cash for the barrier.

On permits: the tunnel needs none. This is the single biggest difference from Rohtang Pass, which does require an online permit and is closed to permits on Tuesdays. Indian travellers need no permit for Lahaul either. Foreign nationals travelling deep into restricted border areas beyond Lahaul should check current inner-line rules for those specific stretches.

Places to visit near Atal Tunnel

The tunnel is a gateway, and the best of a trip here is what sits on either side of it. These are the stops worth building in, roughly in the order you meet them heading north.

• Solang Valley sits on the way up, about 12 km short of the portal. Paragliding, zorbing and the ropeway in summer; a snow-play field in winter.

• Sissu is the first Lahaul stop, about 10 km past the North Portal. A roadside waterfall, the Sissu lake and wide meadows make it the natural place to stop, eat and turn around on a day trip.

• Koksar about 20 km on, is the old first-village check-post with a cluster of hot-food dhabas, the traditional break on the Lahaul road.

• Gramphu is the junction, roughly 22 km from the tunnel, where the road forks right for Spiti (Chandratal, Kaza) and left for Keylong and Leh.

• Rohtang Pass sits above the tunnel and is the classic snow-point, reached separately over the old road with a permit.

• Keylong the Lahaul district headquarters about 70 km on, is the main overnight town on the Leh route with fuel, food and guesthouses.

• Jispa and the Baralacha La approach beyond Keylong, is the popular riverside halt for anyone continuing to Leh, with Baralacha La the next high gateway.

• Gondhla near Keylong is worth the short detour for the multi-storey Gondhla Fort, a piece of old Lahauli heritage.

• Tandi is the Chandra and Bhaga confluence and the last reliable fuel stop before Leh, so top up here.

• Chandratal the crescent-shaped high lake in Spiti, is reached via the Gramphu turn-off and is the headline stop if you branch towards Spiti.

Things to do around Atal Tunnel

The crossing itself takes ten minutes, so the day is really about what you do at either end.

• Sissu stop: at Sissu, walk to the waterfall, sit by the lake and let the kids loose in the meadow. In winter this whole bowl is a snow field.

• Solang activities: back at Solang, ride the ropeway, try zorbing, or paraglide in summer.

• Snow play: in winter, the north-portal side and Sissu get reliable snow for sledging and photos without the Rohtang permit hassle.

• Road trip: use the tunnel as the launch point for a two or three day run to Chandratal and Kaza, or a longer Manali to Leh drive.

If you want to build the Spiti leg in, our Chandratal how to reach guide and the Solang Valley skiing guide both start from this road.

What to carry and before you go

Lahaul is high and cold even when Manali is warm, so pack for it.

• Warm layers: even in June it is cold inside the tunnel and at Sissu; carry a windproof jacket. In winter, add proper layers, gloves and waterproof boots.

• Fuel: fuel up in Manali. The next reliable pumps are at Tandi, well past Keylong.

• Network: mobile network is patchy the moment you cross into Lahaul; download offline maps and tell someone your plan.

• Documents and cash: carry ID, and cash for the Sissu barrier and small dhabas.

• Altitude: you gain altitude quickly. Take it slow, hydrate, and do not push on to Chandratal or high passes if anyone shows altitude symptoms.

One safety note that reassures nervous drivers: the tunnel has an escape tube running beneath it, CCTV along its length, and emergency call points, so it is one of the safest stretches on the whole route.
