Sarchu sits at 14,070 feet on the Manali-Leh Highway, right at the border of Himachal Pradesh and Ladakh. It is one of the most common overnight stops for travelers heading to Leh by road. It is also one of the most common places where Acute Mountain Sickness (AMS) strikes hard. We learned this the painful way on our very first trip to Ladakh back in 2018, and the lessons from that night at Sarchu have stayed with me ever since.
Practical Info: Sarchu (14,070 ft / 4,290 m) is the midpoint of the Manali-Leh Highway, approximately 222 km from Manali and 250 km from Leh. Accommodation is limited to tent camps and the Army Transit Camp. There is no permanent settlement here, no mobile network, no petrol pump, and no medical facility. The nearest hospital is at Keylong (about 105 km back towards Manali).
In this post, I will share what actually happened to us at Sarchu, the symptoms we experienced, the mistakes we made, and what you should do instead. If you are planning a trip to Ladakh via the Manali-Leh route, this is one experience I genuinely hope you can learn from without having to repeat it yourself.
This post continues from my previous story on Baralacha La Pass, which describes the journey leading up to Sarchu.
Let's quickly dive into the details:
Why Is AMS So Common at Sarchu on the Manali-Leh Highway?
The reason AMS hits so many travelers at Sarchu is the rapid altitude gain on the Manali-Leh Highway. You start your day at Manali (6,725 ft), cross the Atal Tunnel, and by evening you are sleeping at 14,070 ft. That is a gain of over 7,000 feet in a single day. Your body simply does not get enough time to acclimatize.
To put this in perspective, the recommended rate of ascent above 10,000 ft is about 1,000 ft per day. When you drive from Manali to Sarchu, you are effectively gaining seven days’ worth of altitude in one day. No wonder your body protests.
The Manali-Leh Highway also takes you over multiple high passes before Sarchu. After the Atal Tunnel, you still cross Baralacha La (16,040 ft) before descending to Sarchu. So your body is being pushed to extreme heights even before you settle in for the night. Compare this to the Srinagar-Leh Highway, where the ascent is far more gradual and AMS cases are significantly fewer.
Altitude is categorized as follows:
- High Altitude: 8,000 to 12,000 ft. Mild symptoms possible for first-timers.
- Very High Altitude: 12,000 to 18,000 ft. AMS is common here. Sarchu (14,070 ft), Pang (15,280 ft), and Tanglang La (17,480 ft) fall in this range.
- Extremely High Altitude: 18,000 ft and above. Severe AMS risk. Khardung La (17,582 ft) and Chang La (17,585 ft) approach this zone.
It is a good practice to gain only about 1,000 ft of sleeping altitude every 24 hours above 10,000 ft. Hence, it is far better to stay overnight at Jispa or Keylong instead of pushing all the way to Sarchu on your first day.
What Happened to Us at Sarchu? Our AMS Experience
Our land is so barren and the passes are so high that only the best of friends or fiercest of enemies would want to visit us
Local Ladakhi Saying
Around 9 PM, we were nearing Sarchu after a long and exhausting day of driving from Manali. The daylight had completely gone, and without any light, the spectacular views of the highway were invisible to us. We literally saw no one on the road after Zingzing Bar, and the isolation was very real.
Pro Tip: Please avoid traveling at night on this route, and in Ladakh in general. The roads are narrow, unpaved in sections, and there is no lighting whatsoever.
The moment we reached Sarchu, we were overjoyed. The moment we got out of the car, we were freezing. Still living in the moment, we were not thinking about what was coming. My friend already had a terrible headache and just wanted to sleep. Since we were staying at the Army Transit Camp, a camp medic came to check on us. Most of us had oxygen saturation levels in permissible limits but elevated blood pressure. We were advised to drink plenty of lukewarm water.
What Does AMS Actually Feel Like? The Night at Sarchu
After eating food, I made the brilliant mistake of taking a shower. Each step felt like an effort, each breath required concentration, and here I was, ignoring it all and exerting myself further. The cherry on top was when my hair dryer refused to work. I was genuinely scared. Thankfully, a friend came to my rescue. She helped me warm up, and I honestly believe she saved me from a much worse night.
With much effort, doubling up on quilts, we got into our bunk beds. Everyone was freezing and shivering. You could hear the struggle as people tried to warm up. None of us slept well. Every so often, someone would wake up gasping, some were already awake staring at the ceiling, and some were snoring intermittently between bouts of restlessness.
It was not a happy night. As we had planned an early start, the alarm was set for 5 AM. But even before it went off, everyone was awake. Nobody was moving though, each of us fearing we might disturb the sleep of any lucky soul who had managed to catch a wink or two.
When the alarm finally rang, everyone jumped out. Well, “jumped” is a generous word. It was more like a slow-motion scene from a movie, given how much energy even standing up required. Brushing teeth was an ordeal. Just applying toothpaste on the brush took all the life I had in me.
However, that first look at Sarchu the moment we stepped outside, the beauty of barrenness stretching in every direction, the first mountain sunshine on our faces, bundled up in every warm layer we owned. It was magnificent. And just like that, the night felt worth it.
How Did Each Person in Our Group Experience AMS?
Once we started driving again, the mood lightened up, and we began sharing our “Sarchu War Stories” (we almost trademarked the term). Here is what each person in our group went through:
- #1: Slept in shorts and a t-shirt (the only way he knew how to sleep). Got up in the middle of the night to pee, and shivered so hard that actual tremors passed through the floor, waking everyone up.
- #2: Got paranoid about dying. Drank water as advised. Threw up in the morning and continued vomiting multiple times throughout the day.
- #3: Got scared of getting up to pee because #1 had shivered so violently.
- #4: Constant headache and blood in nostrils. This was something most of us experienced throughout the trip.
- #5: As the doctor in our group, she was more concerned about everyone else’s breathing than her own symptoms. Kept cursing herself for not packing enough warm clothes.
- #6: Had a full existential crisis. “What the hell did I do? Is this too much adventure? Maybe we should go back!”
Himalayan Lesson: The most important things are the ones we never think about. Oxygen, warmth, and a good night’s sleep become luxury items at 14,000 feet.
How Did the Sarchu Experience Bring Our Group Closer?
What came out of that terrible night at Sarchu, however, was something unexpected. An incredible sense of bonding. We had lived through this together, huddled up in one room, in bunk beds, listening to each other breathe (and struggle to breathe). There is something about shared suffering in the Himalayas that creates friendships you cannot build anywhere else.
Himalayan Lesson: Your tribe defines your vibe. Travel with people you trust.
Every time someone in the group got irritated (irritability is one of the many symptoms of AMS, by the way), we would crack a Sarchu joke and the tension would dissolve. Every comparison for the rest of the trip was to Sarchu. The dread of having to return through the same place on our way back was epic. Sarchu became our trip’s villain and inside joke, all rolled into one.

What Should You Do to Avoid AMS at Sarchu?
Now that I have shared what went wrong with us, here is the practical advice that I wish someone had hammered into our heads before we left. Keep in mind, AMS can affect anyone regardless of age, fitness level, or prior experience at altitude. There is no guaranteed way to prevent it, but these steps significantly reduce your risk.
- Stay at Jispa or Keylong instead of Sarchu: This is the single most effective thing you can do. Jispa sits at about 10,600 ft, and Keylong at about 10,100 ft. Both are comfortable altitudes for your first night stop. Start early the next morning and push to Leh in one long day, crossing Sarchu and Pang during daylight without sleeping there.
- Drink water constantly: Track the color of your urine. It should be clear. If it turns dark, you are not drinking enough. Carry your own bottles and refill at every opportunity.
- Do not over-exert yourself: At 14,000 ft, even mundane tasks like walking and breathing require effort. Do not take showers (yes, I learned this the hard way). Do not run. Do not do anything that raises your heart rate unnecessarily.
- Consult your doctor about Diamox: Acetazolamide (Diamox) is commonly prescribed as a preventive measure. Important: it should be started at low elevation, at least one day before you gain altitude, not after you reach high altitude. Standard dosage is 125-250 mg twice daily. Always consult your doctor before taking it.
- Carry Camphor (Kapur): This became our group’s best friend on the trip. Wrap a piece of camphor in a handkerchief and inhale from time to time. It provides a brief sensation of easier breathing. It was the thing we passed around in a circle. It was our bonding object at altitude.
- Avoid alcohol and cigarettes: Both cause dehydration, which worsens AMS symptoms significantly.
- Know the Army Transit Camps: There are Army Transit Camps at multiple points on the Manali-Leh Highway. If you feel something serious is happening, stop at one of these camps immediately. The army personnel are experienced with altitude sickness and will help you. We met a convoy of jawans heading to Jammu who specifically encouraged us to use these camps if needed.
- If symptoms worsen, descend immediately: This is the most critical rule. If headache becomes severe, if you experience confusion, loss of balance, or persistent vomiting, you must descend to a lower altitude right away. AMS can progress to HACE (High Altitude Cerebral Edema) or HAPE (High Altitude Pulmonary Edema), both of which are life-threatening.
Water is your best friend at altitude. Carry your own bottles and keep sipping throughout the day. Do not wait until you feel thirsty.
Where Should You Stay Instead of Sarchu on the Manali-Leh Route?
If I had to do this trip again, I would plan my night stops very differently. Here is what I recommend based on my experience and what I have learned since 2018.
Option 1 (Recommended for first-timers): Stay at Jispa (10,600 ft) or Keylong (10,100 ft) on Day 1. These towns have proper hotels, restaurants, and mobile connectivity. Start by 4-5 AM the next day and drive to Leh (about 350 km, 12-14 hours). You will cross Baralacha La, Sarchu, Pang, and Tanglang La during the day, giving your body time to adjust as you move.

Option 2 (For those who must stop at Sarchu): If your vehicle is slow or you started late from Manali, you may have no choice but to stay at Sarchu. In that case, arrive as early as possible, drink lots of water, eat light carb-heavy food, avoid exertion, and sleep with your head slightly elevated. Most importantly, do not panic. Mild AMS symptoms (headache, nausea, difficulty sleeping) at Sarchu are extremely common and will usually resolve once you continue to Leh the next day.
Option 3 (Two-day drive): Break the Manali-Leh drive into three days instead of two. Stay at Jispa on Day 1, Pang or Sarchu on Day 2 (by now your body has had an extra day to adjust), and reach Leh on Day 3. This is the safest approach but requires more time.

What Are the Common Symptoms of AMS You Should Watch For?
Based on our group’s experience at Sarchu and subsequent trips to Ladakh, here are the symptoms you should be aware of. AMS can range from mild discomfort to a medical emergency, so knowing what to look for is critical.
Mild AMS (common at Sarchu, Pang, and above 12,000 ft):
- Headache (the most universal symptom)
- Difficulty sleeping or restless sleep
- Loss of appetite or mild nausea
- Fatigue and general weakness
- Dizziness or lightheadedness
- Shortness of breath during exertion
- Irritability (yes, getting inexplicably annoyed at your travel companions is a real symptom)
Severe AMS (requires immediate action):
- Persistent vomiting
- Severe headache that does not respond to painkillers
- Bleeding from nostrils (we experienced this)
- Confusion or disorientation
- Loss of coordination or inability to walk straight
- Blue or gray lips/fingernails (sign of oxygen deprivation)
- Gurgling sound while breathing (potential HAPE)
If you or anyone in your group shows severe symptoms, do not wait until morning. Descend immediately, even if it means driving at night. Severe AMS can progress to HACE or HAPE within hours, and both require emergency medical attention. The nearest medical facilities on the Manali-Leh route are at Keylong (back towards Manali) or Leh (forward). You can also read more about renting oxygen cylinders in Leh and the detailed AMS prevention guide on this blog.
Should AMS at Sarchu Stop You from Visiting Ladakh?
Absolutely not. And I say this as someone who had a genuinely terrible first night at Sarchu. AMS is common, but it is also manageable if you prepare well. The key is respect. Respect the altitude, respect the pace of acclimatization, and respect your body’s signals.
You do not need to be physically unfit to experience AMS. Ladakh is a high-altitude desert, and even seasoned trekkers and athletes can be affected. The good news is that with proper planning, choosing the right night stops, staying hydrated, and knowing when to descend, you can significantly reduce your risk. If you are a first-time self-driver heading to Ladakh, please take the acclimatization advice seriously. It can make the difference between a trip you remember fondly and one you remember for all the wrong reasons.
The path ahead from Sarchu was not easy either. But with Sarchu behind us, we felt more prepared, more bonded, and oddly more alive. The next morning brought the magic of More Plains, the thrill of back-to-back passes, and the pure joy of Himalayan sunshine. Sarchu tested us, and we passed. Barely, but we passed 🙂

If you are planning your first trip and worried about altitude sickness, feel free to ask in the comments or reach out through the DwD Community. We have all been through it, and we are happy to help, my friend.
Frequently Asked Questions
Is it safe to sleep at Sarchu on the Manali-Leh Highway?
Sleeping at Sarchu is physically safe, but there is a high risk of experiencing AMS symptoms because of the altitude (14,070 ft). Most travelers experience headache, nausea, and difficulty sleeping. If you are a first-timer, it is much better to stay at Jispa (10,600 ft) or Keylong (10,100 ft) instead, and cross Sarchu during the day the next morning.
What is the altitude of Sarchu and why does AMS happen there?
Sarchu sits at 14,070 ft (4,290 m) on the Manali-Leh Highway. AMS happens here because travelers gain over 7,000 ft of altitude in a single day when driving from Manali. The recommended rate of ascent is only 1,000 ft per day above 10,000 ft, so the rapid gain overwhelms the body’s ability to acclimatize.
Can Diamox prevent AMS at Sarchu?
Diamox (Acetazolamide) can help reduce the severity of AMS symptoms but does not guarantee prevention. It should be started at low altitude, ideally one day before you begin gaining altitude, at a dosage of 125-250 mg twice daily. Always consult your doctor before taking Diamox, especially if you have kidney issues or sulfa allergies.
What should I do if I get severe AMS at Sarchu?
If you experience severe symptoms like persistent vomiting, confusion, loss of coordination, or difficulty breathing, you must descend to a lower altitude immediately. Drive back towards Keylong (105 km, about 10,100 ft). Do not wait for morning. Severe AMS can progress to life-threatening HACE or HAPE within hours. The Army Transit Camp at Sarchu has basic medical facilities and can provide oxygen.
Is Jispa better than Sarchu for an overnight stop on the Manali-Leh route?
Yes, Jispa is significantly better for your first night stop. At 10,600 ft, Jispa is nearly 3,500 ft lower than Sarchu, which gives your body much more time to adjust to the altitude. Jispa also has proper hotels, restaurants, mobile connectivity, and the Tandi petrol pump is only 32 km away. Start early the next morning and you can reach Leh the same day.
What accommodation is available at Sarchu?
Sarchu has tent camps (typically Rs 1,500-3,000 per person including meals, as of 2024, verify locally for current rates) that operate from June to September. The Army Transit Camp is another option if space is available. There are no permanent hotels, no Wi-Fi, no mobile network, and no petrol pump at Sarchu. Accommodation is basic, and you should carry your own sleeping bag for extra warmth.
Does AMS only affect unfit people?
No. AMS can affect anyone regardless of age, fitness level, or prior altitude experience. In our group, the fittest member was actually the one who suffered the most. Physical fitness does not protect you from altitude sickness. The only reliable preventive measure is gradual acclimatization, which means gaining altitude slowly and giving your body time to adjust to lower oxygen levels.
