You can drive to Sissu in winter when the valley is open — the Atal Tunnel stays open through most of the season — but the snow and black ice are on the approaches, not inside the tunnel. So you need good tyres (ideally a 4×4 with chains), an early start, a full tank from Manali, and one firm rule: never drive on in a storm or after dark. Get those right and the winter crossing into Lahaul is one of the most beautiful drives in the Himalaya. Rush it and it becomes the opposite. As hosts who live on the valley floor, here is exactly how we would tell a friend to do it.
Can you drive to Sissu in winter?
Yes — for most of the winter you can, and plenty of self-drivers do. The thing that makes it possible is the Atal Tunnel. Before it opened, reaching Lahaul in winter meant the Rohtang Pass, which shuts under snow for roughly half the year. The tunnel runs under the mountain instead of over it, so the Manali–Sissu route stays usable when the old pass is buried. The drive is only about 38–40 km and, in good conditions, 1–1.5 hours, with the tunnel’s north portal about 12 km from Sissu on the Lahaul side.
The honest caveat is the one word conditions. The tunnel itself is engineered to stay open through winter, but the open road on either side of it collects fresh snow and ice, and after a heavy fall the authorities may hold traffic for a few hours while machines clear it. So “can you drive?” really means “can you drive today?” — and that answer changes with the weather. There is also a longer closure to know about: in the deepest part of winter, roughly late January into February, the valley usually sees a tourism suspension of around 40 days. We cover that at the end, and keep our is Sissu open right now page current so you can check before you commit. When in doubt, call us the day before — we will tell you what the road is actually doing.
Road & tunnel conditions in winter
It helps to picture the drive in three parts, because each behaves differently in the cold:
- The Manali-side approach (south). This is where most winter trouble sits. The climb from Manali up toward the south portal is shaded in places, gathers snow, and can glaze into black ice on cold mornings — the thin, near-invisible film that catches drivers out. After fresh snow there may be a clearance hold here while ploughs work.
- Inside the tunnel. The 9.02 km Atal Tunnel is the easy, dry, sheltered part — no snow, no ice. Just follow the rules: 60 km/h limit, headlights on, keep your distance, and no stopping or photography. Read our Atal Tunnel timings & rules guide before you go.
- The Lahaul-side approach (north) to Sissu. The last ~12 km down into the valley can carry packed snow and ice too, especially early and late in the day before the sun has touched the road. It is short, but take it gently.
The takeaway most people miss: the scary part is never the tunnel — it is the ordinary snow-covered road on either side. Treat the approaches with respect and the crossing is very manageable. For the full route breakdown, see how to reach Sissu.
Vehicle & gear you need
Winter is not the season to attempt this in a low, bald-tyred hatchback loaded to the roof. You do not necessarily need a monster off-roader, but you do need the right basics:
- Good tyres first. Tyres matter more than anything else — more than the badge on the bonnet. Deep tread with plenty of grip is the single biggest safety factor on snow and ice.
- Ideally a 4×4 / AWD. A four-wheel-drive with decent ground clearance handles the packed-snow approaches far more confidently than a two-wheel-drive car. Many experienced visitors bring one for exactly this reason.
- Carry snow chains. Even a capable vehicle can meet a stretch that demands chains. Carry a set that fits your driven wheels, and — importantly — practise fitting them once before you are doing it with cold hands on an icy verge.
- A full tank from Manali. There is no petrol pump in Sissu — the next fuel toward Keylong is at Tandi. Fill up completely in Manali before you cross; a warm engine and a full tank are both winter safety items. Our ATM & petrol network in Sissu guide has the detail.
- Cold-weather kit in the car. Warm layers, gloves, a blanket, water, snacks, a torch, a basic shovel and a tow rope. If you are ever held up by a clearance, you want to be warm and self-sufficient. See what to pack for Sissu.
None of this is about expecting the worst — it is simply what turns a nervous drive into a calm one.
Timing & golden rules
In winter, when you drive matters as much as what you drive. A few rules we would never break ourselves:
- Start early. Leave Manali in the morning so you cross and arrive with hours of daylight in hand. An early start gives you a buffer for any clearance hold and gets you off the road before the light goes.
- Never drive after dark. Ice you could read in daylight becomes invisible at night, temperatures drop, and there is no room for error on a snow-narrowed mountain road. Plan every winter leg to finish before dusk.
- Never push on in a storm. If it is actively snowing hard or visibility collapses, stop and wait it out somewhere safe rather than press on. Weather here can turn fast; a lost hour is nothing next to the alternative.
- Check conditions the day before — and the morning of. A quick call to us, or a look at is Sissu open right now, tells you whether today is a driving day or a wait day.
- Build in flexibility. Winter travel and rigid schedules do not mix. Leave a spare day if you can, so a clearance hold is an inconvenience, not a crisis.
Follow that rhythm and you take almost all the risk out of the drive. The road rewards patience and punishes hurry — every winter, the trouble finds the people who were racing the dark.
Hiring a local driver vs self-drive
If you are at all unsure about snow driving, the simplest safe answer is to not drive yourself. A local driver does this road in every kind of weather, reads the ice you cannot, knows which stretches glaze first, and stays calm when a clearance hold appears. For many of our winter guests, handing the wheel to someone who knows the valley is the best decision they make.
Broadly, here is how we frame the choice:
- Self-drive suits confident cold-weather drivers with the right vehicle (good tyres, ideally 4×4, chains aboard) who want the freedom to stop and explore — and who will hold firmly to the golden rules above.
- A hired taxi or local driver suits anyone new to snow, travelling with family, or simply wanting to enjoy the scenery instead of gripping the wheel. It is also the easier option if you would rather not risk your own car on ice.
For how taxis and shared cabs work and roughly what they cost, see our Manali to Sissu taxi & bus fare guide. Whichever you choose, our travel desk can help you arrange a reliable driver for your dates and tell you honestly whether self-drive makes sense for the conditions that week.
If the valley is closed (winter suspension)
There is one window when the answer to “can I drive to Sissu?” is simply no. In the deepest cold, usually from late January into February, the valley typically has a tourism suspension of around 40 days while conditions are at their most severe. During that spell, hotels in the valley — ours included — generally do not take guests, and you should not be planning a self-drive up regardless of how capable the car is.
The dates shift year to year with the weather, so the rule is straightforward: before you book any late-January or February trip, confirm the valley is open. Our is Sissu open right now page tracks the current status, and a quick message to us settles it instantly. Outside that window — December, early January, and again from around March — winter driving to Sissu is very much on, with the precautions on this page.

Frequently Asked Questions
Can you drive to Sissu in winter?
Yes, for most of the winter you can — the Atal Tunnel keeps the Manali–Sissu route open when the old Rohtang Pass is closed. The drive is about 38–40 km and 1–1.5 hours in good conditions. The catch is the weather: the approaches on either side of the tunnel gather snow and black ice, and after heavy falls there can be short clearance holds. Always check conditions before you set off, and note the roughly 40-day tourism suspension in the deepest winter (late January into February).
Is the Atal Tunnel open in winter?
Yes — the 9.02 km Atal Tunnel is engineered to stay open through most of the winter, which is exactly why Sissu is reachable in the cold months. The tunnel itself is dry and sheltered, with no snow or ice inside. The snow and ice are on the open approach roads on either side of it, so that is where you need to drive carefully.
Do I need a 4x4 to drive to Sissu in winter?
Not strictly, but it helps a lot. Good tyres with deep tread matter most of all; on top of that, a 4×4 or AWD with reasonable ground clearance handles the packed-snow approaches far more confidently than a two-wheel-drive car. Whatever you drive, carry snow chains and know how to fit them — some stretches may need them.
Is there black ice on the road to Sissu?
Yes, black ice is the main hazard in winter, especially on shaded sections of the Manali-side approach and on cold early mornings and evenings before the sun reaches the road. It is thin and hard to see. Drive slowly and smoothly, avoid sudden braking or steering, and never drive after dark when the ice is invisible.
Where do I fill fuel for the winter drive to Sissu?
Fill up completely in Manali before you cross the tunnel — there is no petrol pump in Sissu. The next fuel toward Keylong is at Tandi. A full tank is a winter safety item, not just convenience, so never set off low.
Should I self-drive or hire a driver to Sissu in winter?
If you are confident on snow and have the right vehicle (good tyres, ideally 4×4, chains aboard), self-drive is fine as long as you follow the golden rules — early start, never after dark, never in a storm. If you are new to snow, travelling with family, or would rather not risk your own car on ice, hire a local driver who knows the road in every condition. We can help arrange one for your dates.
