The short version: Cycling Manali to Leh covers roughly 474 km over five high passes, and a typical itinerary runs 10 days — one to arrive and acclimatise, eight riding days to Leh, and an optional summit day to Khardung La. The highest point on the main highway is Tanglang La at about 5,328 m; add Khardung La and you top out at 5,359 m. The season runs from roughly mid-June to mid-September. It is not a technically difficult ride — the challenge is doing it day after day on half the oxygen you are used to.
This is the ride that sits on more cyclists' lists than almost any other in Asia, and for good reason. In under two weeks you go from pine forest and apple orchards outside Manali to a high-altitude desert that looks like another planet. But it also catches a lot of people out, and almost always for the same reason: they train for the distance and not for the altitude.
We have been running bicycle rentals, servicing and guided tours out of Manali since 2018, and we see riders at both ends of this — the ones who set off from our shop properly prepared, and the ones who come back down early. This guide is what we tell people who walk in and ask how to do it.
What this guide covers
The route and the passes
The Manali–Leh highway runs about 474 km. Nearly all of it sits above 3,000 m, and a large share sits above 4,000 m. You cross five named passes on the highway itself, and a sixth if you continue to Khardung La north of Leh.
One thing worth clearing up straight away: the altitudes painted on the signboards at the top of these passes are frequently wrong, sometimes by hundreds of metres. Khardung La's sign has claimed 5,602 m for decades, and shops in Leh sell t-shirts with that number on them, but GPS surveys and official Indian topographic mapping put it at 5,359 m. It is still an extraordinary place to ride a bicycle. It just is not quite what the sign says.
| Pass | Altitude | Where it falls |
|---|---|---|
| Rohtang La | ~3,978 m | Day 3, above Manali |
| Baralacha La | ~4,890 m | Day 6, above Zingzingbar |
| Nakee La | ~4,739 m | Day 7, top of the Gata Loops |
| Lachulung La | ~5,059 m | Day 7, same day as Nakee La |
| Tanglang La | ~5,328 m | Day 9, highest point on the highway |
| Khardung La | ~5,359 m | Day 10, optional, from Leh |
Since the Atal Tunnel opened, there is now a choice at the very start. The tunnel bypasses Rohtang La entirely and cuts a long, cold, exposed climb down to an 8.8 km ride through the mountain. Cyclists are permitted through it — we run a guided day tour through the tunnel to Sissu ourselves, so this is not a grey area. Ride it in daylight, stay well to the left, and be aware that mobile signal drops completely inside. Riding over Rohtang is the harder and more scenic option; the tunnel is faster and much kinder to legs that have not yet acclimatised.
Our rule of thumb: if the group has acclimatised and the weather is clear, we send first-timers over Rohtang. The climb is a rite of passage and the view off the top is something the tunnel simply cannot give you. We route through the tunnel instead when legs are not ready yet, when the group is mixed-ability, or early and late in the season when the weather up on Rohtang turns without warning. The regret we see is almost always the same: riders who insist on Rohtang on day two or three, before they have acclimatised, and burn matches they badly need later on. Whichever you choose, ride the tunnel in daylight, single file, well to the left with your lights on — it is 8.8 km, roughly half an hour, shared with trucks, cold inside, and there is no phone signal the whole way through.
Day-by-day stages
Distances look small on paper. They are not small at 4,500 m. A 45 km day here can take longer and cost more than a 100 km day at home.
| Day | Stage | Distance | Sleep altitude |
|---|---|---|---|
| 1 | Arrive Manali, fit bicycles, brief | — | ~2,050 m |
| 2 | Manali → Marhi | ~36 km | ~3,360 m |
| 3 | Marhi → Sissu (over Rohtang La) | ~52 km | ~3,120 m |
| 4 | Sissu → Jispa | ~48 km | ~3,260 m |
| 5 | Jispa → Zingzingbar | ~39 km | ~4,270 m |
| 6 | Zingzingbar → Sarchu (over Baralacha La) | ~47 km | ~4,290 m |
| 7 | Sarchu → Gata Loops → Nakee La → Lachulung La → Pang | ~78 km | ~4,500 m |
| 8 | Pang → Morey Plains → Debring | ~78 km | ~4,630 m |
| 9 | Debring → Tanglang La → Leh | ~96 km | ~3,500 m |
| 10 | Leh → Khardung La and back (optional) | ~39 km each way | ~3,500 m |
A note on Sarchu: Sarchu sits at around 4,300 m and has a reputation for wrecking people. Sleeping that high, that early in the trip, is a common trigger for altitude sickness. Some operators break the day differently and sleep lower at Jispa or Zingzingbar instead. If you are planning this yourself, look hard at your sleeping altitudes rather than just your daily distances.
We build our itinerary around sleeping altitude, not daily distance, and we deliberately sleep low early. Our default first night beyond the Lahaul valley is Jispa at around 3,300 m rather than Sarchu at around 4,300 m — Sarchu is where we see the most sickness by a wide margin, because it asks people to sleep that high, that early, before their bodies have caught up. When a schedule forces a Sarchu night we get there early, keep the afternoon gentle, and watch everyone closely overnight. We would far rather add a day and keep the jumps in sleeping altitude small than hit a distance target and lose a rider to AMS. If you are planning this yourself, do the same: look hard at where you sleep each night, not how many kilometres you cover.
When to go
The Border Roads Organisation clears the highway each spring once the snow allows. In 2026 they connected both ends on 12 May and two-way traffic was running from 1 June. The road usually closes again around mid to late November. Those dates shift by a couple of weeks each year depending on snowfall.
- Mid-June to end of June — open but still rough. Meltwater stream crossings, slush, and cold nights. Fewer vehicles, which is a real benefit on a bicycle.
- July and August — the most settled and popular window. The main risk is heavy rain in the Lahaul valley causing flash flooding and debris on the road; this happened near Jispa on 30 June 2026 and closed the highway for several hours before BRO cleared it.
- September to early October — arguably the best light and the clearest skies, but nights get seriously cold and an early snowfall can close a pass with little warning.
If you have flexibility, aim for the second half of August into early September. If you have none, July is the safest bet.
The sections that actually hurt
The climb to Marhi
This comes on day two, before anyone has acclimatised, and it catches people out precisely because it is early. It is a long, steady drag with no real respite. Riders who go too hard here often pay for it three days later.
The Gata Loops
Twenty-one hairpin bends stacked up the side of a valley, lifting you from about 4,190 m to roughly 4,630 m. On a bicycle, above 4,000 m, the loops are a psychological test as much as a physical one — you can see the entire climb above you the whole way up.
Nakee La and Lachulung La on the same day
This is the day most riders name as the hardest. You finish the Gata Loops, crest Nakee La, drop, and then immediately climb again to Lachulung La at over 5,000 m. Two major passes, one day, with nowhere comfortable to stop in between.
The Morey Plains
Roughly 40 km of almost dead-flat plateau at about 4,600 m. It reads like a rest day. It is not. There is no shelter, the wind funnels across it, and the sheer monotony grinds people down more than any climb does.
Ask our riders which day was hardest and most name the stage out of Sarchu — Nakee La and Lachulung La, two passes over 4,700 m back to back with nothing comfortable in between. But the section that quietly breaks more people is the Morey Plains. Forty flat kilometres at 4,600 m reads like a rest day on paper and turns into a headwind grind with no shelter and nothing to look at; it wears people down mentally more than any climb. The Gata Loops look terrifying — twenty-one hairpins stacked above you the whole way up — yet riders who pace them calmly almost always surprise themselves. The one that catches the strong riders is the day-two climb to Marhi: they go hard before they have acclimatised and pay for it three days later. If we had to sum it up: on this road the flat plateau ends more attempts than the passes do.
Altitude — the part that ends most attempts
More Manali–Leh attempts end because of altitude than because of fitness or mechanical failure. It is worth understanding properly.
Acute mountain sickness usually shows up between 2 and 12 hours after you gain height. The cardinal symptom is a headache, typically alongside loss of appetite, dizziness, fatigue, nausea and disturbed sleep. It feels remarkably like a bad hangover. Being fit does not protect you — if anything, fit riders are more at risk because they push harder and gain height faster.
The general guidance from wilderness medicine bodies is to avoid gaining more than about 500 m in sleeping altitude per night once you are above 3,000 m, and to build in a rest day every 1,000 m or so. Cycling makes this harder than travelling by vehicle, because sustained hard effort accelerates the effects of thin air.
Know the line between AMS and an emergency. Mild AMS — headache, poor appetite, bad sleep — is common and usually settles if you stop gaining height. But confusion, an inability to walk in a straight line, breathlessness at rest, or a persistent wet cough are signs of high-altitude cerebral or pulmonary oedema. Both are life-threatening and both are treated the same way: descend immediately, at night if necessary, and get medical help.
This guide is general information, not medical advice. Talk to a doctor before the trip, particularly about whether acetazolamide is appropriate for you, and tell your guide honestly how you are feeling rather than pushing through.
Practical things that genuinely help: drink far more water than feels necessary, eat carbohydrate even when you have no appetite, avoid alcohol entirely for the first few days, and ride at a pace where you could still hold a conversation. If in doubt, go slower.
Our rule is simple and not up for debate: if symptoms do not settle once you stop climbing, you go down. Mild AMS — a headache, no appetite, broken sleep — we manage on the spot: stop gaining height, hydrate hard, eat carbohydrate, rest. But confusion, breathlessness at rest, loss of coordination or a wet cough and the rider goes straight into the support vehicle and descends immediately, at night if that is when it happens. We carry oxygen and a first-aid kit on the expedition and the support jeep is never far behind the group. The single thing we ask of every rider is to tell the guide honestly how they feel instead of pushing through — the people who get into real trouble on this road are almost always the ones who hid symptoms until they got worse. Descent is the only real cure; everything else just buys time.
How fit you need to be
You do not need to be fast. You need to be durable. The single best predictor of whether someone enjoys this ride is whether they have done back-to-back long days before.
A reasonable benchmark, three months out:
- Comfortable riding 60–80 km in a day without it wrecking you
- Able to do that on two or three consecutive days
- Some experience of climbs lasting an hour or more
- At least a few rides on loose or broken surfaces, not just tarmac
Long, steady rides at conversational pace are far more useful preparation than short hard intervals. The ride rewards people who can sit at a modest effort for six hours, not people with a big sprint.
Bicycle and gear setup
A hardtail mountain bike with a wide gear range is the most common choice and the most forgiving. Gravel and touring bikes work well provided they take tyres of at least 35 mm. Full-suspension is unnecessary weight for this.
What matters more than frame type:
- Gearing. Fit lower gears than you think you need. Cadence is your friend at altitude — grinding a big gear at 4,500 m is how you empty the tank.
- Fit. A bike that fits badly becomes agony by day four. Get properly set up before you leave, not on day one.
- Tyres. 35 mm and up, with some tread. The surface alternates between good tarmac, gravel, and stretches that are essentially riverbed.
- Mudguards. At minimum a front guard — meltwater crossings will otherwise spray straight into your face.
- Spares. Carry at least four tubes, a spare tyre across the group, a chain link, spare brake pads and a multi-tool you have actually used before.
There are no bike shops between Manali and Leh. Whatever you cannot fix on the roadside, you carry or you do without.
Punctures, always, by a mile — the surface swings between tarmac, gravel and dried riverbed, and pinch flats on the rough descents are the usual culprit. After that it is gear cables stretching, brake pads wearing down fast on the long descents, and the occasional snapped spoke. Remember there is no bike shop for more than 400 km between Manali and Upshi; the roadside places at Koksar, Keylong and Zingzingbar can patch a tyre and little more. In our support vehicle we carry spare tubes, cables, brake pads, a chain tool, spare spokes and a spare bike for the group. The thing riders never pack that we always bring: a proper floor pump — hand pumps are misery at altitude — and far more tubes than anyone thinks they will need. Before you come, learn to fix a flat and change a gear cable with your own hands.
Permits and paperwork
The Manali–Leh highway itself needs no permit. You ride it freely.
Khardung La and the Nubra valley are a different matter — those sit in protected areas and require an Inner Line Permit, arranged in Leh. Indian citizens and foreign nationals apply through slightly different processes, and foreign nationals should allow extra time. On an organised trip your operator will normally handle this for you.
Carry photo ID at all times regardless. There are checkposts along the highway and you will be asked.
Supported or self-supported
Both are legitimate. They are just different trips.
| Supported | Self-supported | |
|---|---|---|
| Luggage | Carried in the vehicle | On the bike, every metre |
| If you have a bad day | Ride in the vehicle, continue tomorrow | You solve it yourself |
| Mechanical failure | Spares and tools on hand | Whatever you carried |
| Altitude problems | Immediate descent possible | Depends on passing traffic |
| Food and water | Arranged | Your responsibility, long gaps between supplies |
| Cost | From around ₹14,999 per person | Lower in cash, higher in risk |
Self-supported riders should be genuinely comfortable being self-reliant. There are long stretches with no phone signal, no shops, and very little traffic — particularly early and late in the season.
Riding it with us
Our 10-day Manali to Leh expedition includes the bicycle and fitting, helmet and gear, guide, support vehicle, camps and meals — finishing on Khardung La.
What to pack
On the bike
- Helmet, gloves, padded shorts, sunglasses with proper UV protection
- Windproof and waterproof jacket — non-negotiable, the descents are freezing
- Layers rather than one thick garment; temperatures swing enormously in a day
- Buff or neck gaiter for dust and cold
- High-factor sunscreen and lip balm. UV at 5,000 m is severe.
Off the bike
- Warm insulated jacket and hat for camp — nights at Sarchu and Pang are genuinely cold
- Sleeping bag rated well below what you think you need
- Headtorch
- Personal first aid, any regular medication, plus rehydration salts
- Water purification — tablets or a filter
- Power bank; charging opportunities are scarce and cold drains batteries fast
- Cash. ATMs effectively do not exist between Manali and Leh.
Common questions
How long does it take to cycle from Manali to Leh?
A typical itinerary runs 10 days: one to arrive and acclimatise, eight riding days covering roughly 474 km to Leh, and an optional summit day to Khardung La. Daily stages run from about 36 to 96 km, which sounds modest until you factor in the altitude.
How difficult is it really?
Hard, but the difficulty is altitude rather than gradient. The climbs are long rather than brutally steep. What makes it demanding is repeating that effort day after day above 4,000 m, where you have roughly half the oxygen of sea level, on surfaces that vary from smooth tarmac to loose gravel and stream crossings.
Can a beginner do it?
A complete beginner should not attempt it. You do not need to race, but you should be comfortable riding 60 to 80 km on consecutive days before you arrive, with some experience of long climbs. Riders who arrive undertrained tend to struggle from day three, when fatigue and altitude start compounding.
Do I need a permit?
Not for the Manali–Leh highway itself. You do need an Inner Line Permit for Khardung La and the Nubra valley, arranged in Leh and usually handled by your operator. Foreign nationals apply under a slightly different process, so allow extra time.
What bicycle do I need?
A hardtail mountain bike with a wide gear range is the most common and forgiving choice. Gravel and touring bikes work if they clear at least 35 mm tyres. Low gearing and correct fit matter far more than the category of bike.
What does it cost?
A fully supported expedition with bicycle, guide, support vehicle, camping and meals starts from around ₹14,999 per person. Self-supported is cheaper in cash but you carry everything, arrange your own accommodation and handle your own mechanical problems in places with no phone signal.
Can I rent a bicycle in Manali rather than bringing my own?
Yes. We rent geared mountain bikes and hybrids from our shop in Manali, serviced and fitted to your height before you leave. If you are joining an expedition the bicycle is normally included.
"How do I know if I'm fit enough?" If you can ride 60–80 km on two or three days in a row without it wrecking you, you are fit enough. Fitness rarely ends this trip — altitude does. Come, and let the mountain set your pace rather than your legs.
"Can I do it in fewer than 10 days?" You can, and the riders who compress the schedule are the ones who get sick. The days are built around how fast a body can safely gain sleeping altitude, not around our convenience. Cutting days cuts your acclimatisation, nothing else.
"What happens if I can't finish a day?" On a supported ride, nothing dramatic — you ride in the vehicle for a stretch and carry on the next morning. Nobody is left on the road, and needing the jeep for an hour is not failure. Self-supported, that same bad afternoon becomes a much bigger problem, which is the real difference between the two ways of doing this ride.
Before you go
If there is one thing to take from all of this: respect the altitude and be honest with yourself about your training. The road will still be there next season. Riders who go slowly, sleep low, eat properly and listen to their bodies almost always finish. Riders who treat it as a fitness challenge frequently do not.
If you are planning a ride and want a straight answer about whether you are ready, message us. We would rather tell you honestly that you need another season of training than take a booking and watch you turn back at Sarchu.
