Sissu to Leh is roughly 335 km along the legendary Manali–Leh Highway — a high, remote, one-to-two-day drive over three great passes: Baralacha La, Lachulung La and Tanglang La. Because Sissu sits just past the Atal Tunnel at about 3,100 m, it makes an ideal first-night acclimatisation halt before you commit to the long haul. Fuel up at Tandi (the last pump for ~360 km), carry a photo ID, and start early. Hotel Lake Side Inn is where many travellers spend that steadying first night.
The route in one glance
The Manali–Leh Highway is one of the highest and most spectacular road journeys on Earth, and Sissu — a few kilometres past the Atal Tunnel on the Lahaul valley floor — sits right on it. From here to Leh you climb out of the Chandra–Bhaga valley, cross Baralacha La (~4,890 m), drop to the Sarchu plains, wind up the Gata Loops to Lachulung La, cross the vast Morey Plains, and finally top out at Tanglang La (~5,328 m) before descending the Indus valley into Leh.
It is not a drive to rush or underestimate. The road is single-lane in long stretches, unpaved in patches, subject to water crossings, landslips and sudden weather, and much of it lies above 4,000 m. Done sensibly — with an acclimatisation night and an early start — it is the trip of a lifetime. Done in a hurry from low altitude, it invites altitude sickness and fatigue. That is exactly why where you sleep the night before matters.
Why start from Sissu
Most people driving to Leh come up from Manali, and the smartest of them do not attempt the whole thing in one go from there. Breaking the journey with a night in Sissu, just past the tunnel, does three useful things at once:
- It starts your acclimatisation. Sleeping a night at Sissu’s ~3,100 m eases your body toward the far higher passes ahead, instead of leaping from Manali’s ~2,000 m straight over 4,000–5,000 m passes in a day.
- It puts you ahead of the clock. The Leh road rewards early starts — passes are calmer, water crossings lower, and you clear the high ground before afternoon weather. From Sissu you are already past the tunnel and hours up the valley when you wake.
- It is close to Tandi fuel. The last petrol pump before the long fuel-less stretch is at Tandi, only ~22 km from Sissu — an easy top-up on the way out.
Practically, that first night is calmer and cheaper than staying in Manali, and you wake to Lahaul’s snow peaks instead of a crowded hill town. Browse our mountain-view rooms — hot water, heaters and free parking — or message us to plan the timing of your run to Leh.
The stages — Sissu to Leh
Here is the classic sequence of landmarks and rough distances from Sissu. Treat the figures as approximate; the road changes with the season and the year.
| Stage | Approx km from Sissu | Notes |
|---|---|---|
| Tandi (fuel) | ~22 km | Last petrol pump — fill up here |
| Keylong | ~30 km | Lahaul district HQ — ATMs, market |
| Jispa | ~50 km | Common overnight halt on the Bhaga river |
| Zingzingbar | ~90 km | Tea tents before the first big climb |
| Baralacha La (~4,890 m) | ~105 km | First major pass |
| Sarchu | ~140 km | HP–Ladakh border plains — camps |
| Pang (via Gata Loops, Lachulung La) | ~215 km | Army transit camp, dhabas |
| Tanglang La (~5,328 m) | ~285 km | Highest point of the drive |
| Leh | ~335 km | Down the Indus valley to journey’s end |
A natural first leg from Sissu is a short one to Jispa, a riverside village about 50 km on that many use as a second acclimatisation stop before Baralacha La — see our Sissu to Jispa route guide for that stretch in detail.
Fuel, food & the Tandi rule
The single most important logistics fact on this route: Tandi is the last petrol pump before Leh, and after it there is no fuel for roughly 360 km. Plan around this rule without exception.
- Fill the tank fully at Tandi (~22 km from Sissu), and if your vehicle’s range is marginal, carry spare fuel in a proper can. There is no reliable pump again until Leh (with limited, unofficial fuel sometimes available at Tandi’s next major point only in emergencies).
- Note there is no petrol pump in Sissu itself. If you have come up from Manali, you will have fuelled there; Tandi is your final scheduled top-up. See our ATM & petrol network in Sissu guide for the full picture on cash and fuel in the valley.
- Carry cash. ATMs thin out fast past Keylong; card and UPI coverage is patchy to non-existent on the high sections. Draw cash in Keylong if you are short.
- Food is dhabas and tent camps. Expect simple hot veg meals — thali, rajma-chawal, Maggi, chai — at Jispa, Zingzingbar, Sarchu and Pang. Carry water, snacks and any medication you need.
Permits, ID & when the road is open
Indian travellers need no permit to drive from Sissu to Leh — just carry a valid government photo ID, as details are checked at posts along the way. Foreign nationals do not need an inner-line permit for the main Manali–Leh Highway itself, but do require Protected Area Permits for certain side regions around Ladakh; check current rules before you travel.
On timing, the highway is a seasonal road. It typically opens once the passes are cleared of snow — broadly from June to October — and closes for winter when heavy snow shuts Baralacha La and Tanglang La, usually from around November. The exact opening and closing dates shift every year with the snow. The Atal Tunnel keeps Sissu reachable for far more of the year, but the road onward to Leh is firmly a summer-and-early-autumn affair. If you are planning near the shoulders of the season, confirm that the passes are open before you commit.
Acclimatising & altitude
This drive takes you from around 3,100 m at Sissu to over 5,300 m at Tanglang La in a single push if you are not careful — and that is how people get altitude sickness. Take it seriously:
- Gain height gradually. A night at Sissu, and ideally another at Jispa or Keylong, lets your body adjust before the big passes. Do not go Manali-to-Leh in one day.
- Hydrate and eat lightly. Drink plenty of water and favour simple, warm food. Alcohol and heavy meals make altitude worse.
- Know the warning signs. Headache, nausea, dizziness and breathlessness are early AMS symptoms. If they worsen, the only real cure is to descend.
- Do not linger at the top of passes. Enjoy the view, take your photo, and keep moving to lower ground to sleep.
Starting your acclimatisation in Sissu is the quiet advantage here — a comfortable, heated room at a moderate altitude is a far better launch pad than a rushed dash from the plains.
How to plan your days
Two sensible ways to split the drive:
- Relaxed (2 nights on the road). Night one in Sissu, night two in Jispa or Sarchu, reaching Leh on day three. Best for acclimatisation and for enjoying the scenery rather than enduring it.
- Faster (1 long day). Overnight in Sissu, then a single big push to Leh — feasible for fit, experienced drivers with an early start, but a genuinely long, high day that raises the AMS risk. Not recommended if it is your first time at altitude.
Either way, the pattern is the same: sleep near the tunnel, fuel at Tandi, start at first light, and respect the mountains. Set your dates and arrival time with us and we will have a warm room and a hot pure-veg dinner ready the night before your big drive — just get in touch.
Frequently Asked Questions
How far is Sissu from Leh?
Sissu to Leh is about 335 km via the Manali–Leh Highway, crossing Baralacha La, Lachulung La and Tanglang La. It is roughly 10–12 hours of pure driving, best split over one or two days with an acclimatisation halt rather than done in a single dash.
Where is the last petrol pump before Leh?
The last fuel is at Tandi, about 22 km from Sissu on the way to Keylong. After Tandi there is no petrol pump for roughly 360 km until Leh, so fill up completely and, if your range is tight, carry spare fuel in a proper can. Note that Sissu itself has no pump.
When is the Sissu to Leh road open?
The Manali–Leh Highway is seasonal, typically open from around June to October once Baralacha La and Tanglang La are cleared of snow, and closed through winter. Exact dates shift each year. The Atal Tunnel keeps Sissu reachable far longer, but the road onward to Leh is a summer-and-autumn route.
Do I need a permit for Sissu to Leh?
Indian travellers need no permit for the main Manali–Leh Highway — just carry a government photo ID for checks along the way. Foreign nationals do not need an inner-line permit for the highway itself but require Protected Area Permits for some Ladakh side-regions; confirm current rules first.
Is Sissu a good place to stop before driving to Leh?
Yes — it is one of the best. At about 3,100 m just past the Atal Tunnel, Sissu is an ideal first-night acclimatisation halt: it eases you toward the high passes, is close to the last fuel at Tandi, and lets you start early. Hotel Lake Side Inn offers heated, mountain-view rooms for exactly this.
How high is the Sissu to Leh drive?
You climb from about 3,100 m at Sissu to a high point of around 5,328 m at Tanglang La, one of the world’s highest motorable passes, with Baralacha La (~4,890 m) along the way. Because of this, gradual acclimatisation and an early start are essential to avoid altitude sickness.
