Nyenchen Tanglha Mountains stretch about 1,500 kilometers long, with an average altitude of 5,000 to 6,000 meters. Covering an area of about 1,961 square kilometers, Namtso Lake is the second largest saltwater lake in China. In Tibetan legends, Nyenchen Tanglha Mountains are regarded as a mountain god, and Namtso Lake is his wife. The trekking starting point is near Damxung County, about 160 kilometers from Lhasa, with streams and tents of northern Tibetan herdsmen along the way. Zhaxi Peninsula, the end point, is the largest peninsula extending into the lake and a common site for visiting Namtso Lake.
The altitude rises gradually from 4,300 meters to the 5,330-meter pass, then drops to 4,718 meters. The whole route is at high altitude, which requires high cardiorespiratory function. First-time visitors to the plateau are advised to acclimatize in Lhasa or Damxung for two to three days before departure.

Land Route to Tibet
It takes one day to travel from Kathmandu to Gyirong Port by car, and one to two days from Gyirong to Lhasa. Road conditions are complex with some mountainous sections; it is recommended to arrange vehicles and drivers through a travel agency. This method is suitable for those who are not in a hurry and want to acclimatize to rising altitude gradually.
Qinghai-Tibet Railway
The train from Xining takes about 20 hours, with sleeper tickets cheaper than flight tickets, and allows gradual acclimatization to altitude. Train tickets are in short supply in peak seasons and need to be booked in advance through official channels or travel agencies. The altitude exceeds 5,000 meters when passing Tanggula Pass, and some passengers may suffer from altitude sickness; medicine preparation in advance is advised.
Lhasa to Damxung
Shuttle buses to Damxung depart from Lhasa East Passenger Station. After arriving in Damxung, you need to continue to the trekking start. Damxung County is about 60 kilometers from Namtso Lake area. The advantage of chartered vehicles is that you can stop and take photos at the Nyenchen Tanglha Mountains viewing platform; it is recommended to confirm with the driver in advance whether the price includes fuel costs and waiting time.

Supplies and Water Sources for Trekking from Nyenchen Tanglha Mountains to Namtso Lake
- There are no shops or supply points along the entire route; all food and fuel must be carried by yourself.
- Streams are available for water replenishment along the way, but water must be treated before drinking.
- There is no stable water source near the pass; fill up water at the valley camp before crossing the pass.
- Recommended staple foods include instant noodles, ready-to-eat rice, compressed biscuits, plus high-energy snacks.
- Daily calorie intake is recommended to be more than 3,000 kcal, otherwise physical strength will drop significantly.
Streams look clear, but it is recommended to treat water with water purification tablets or portable water purifiers before drinking. Water purification tablets usually take 30 minutes to take effect. Drinking untreated water may cause diarrhea, which leads to dehydration and increases the risk of altitude sickness at high altitudes. Staple foods can include instant noodles, ready-to-eat rice, compressed biscuits, oatmeal, etc. High-energy snacks include nuts, chocolate, energy bars, dried meat. Physical strength will decline noticeably after a few days of walking with daily calorie intake below 3,000 kcal. Those with special dietary needs must prepare enough food before departure, as there are no alternatives on this remote trekking route. Check stoves and gas canisters in advance to ensure normal operation, as some stoves have lower combustion efficiency in plateau environments.
Safety Precautions for Trekking from Nyenchen Tanglha Mountains to Namtso Lake
- For mild altitude sickness, slow down walking, drink plenty of warm water and take painkillers; in case of severe headache, persistent vomiting or confusion, descend to lower altitudes immediately.
- Plateau weather changes rapidly; camp in a sheltered spot if weather worsens, and do not risk crossing the pass.
- Some sections lack obvious markers; visibility is very low in fog or heavy snow, so it is better to wait for better weather on site or return along the original route with GPS.
- It is recommended to travel with at least two people; do not act alone.
- Be sure to purchase travel insurance covering plateau rescue, and confirm whether the insurance clause explicitly covers high-altitude trekking.
Headache, nausea, insomnia and loss of appetite are common symptoms of altitude sickness. In case of severe headache, persistent vomiting, unsteady walking or confusion, descend to lower altitudes immediately. Do not push through or continue climbing with severe altitude sickness. Seek medical attention promptly if symptoms do not relieve after descending. Plateau weather changes fast, with sunny mornings and sudden hail or snow in the afternoon. Once weather deteriorates, judge in advance whether to camp in a sheltered spot.
Although this route is relatively mature, some scree and lake basin sections lack clear markers. Visibility may drop below 10 meters in fog or heavy snow; it is best to wait on site or return along the original route with GPS. High-altitude trekking carries high risks, and medical facilities in Tibet, China are limited, especially in remote areas. Emergency rescue and evacuation are costly in case of severe altitude sickness. When purchasing travel insurance, confirm whether it explicitly covers trekking above 5,000 meters and includes helicopter rescue costs. China Dragon Travel advises guests to purchase suitable insurance when arranging itineraries to ensure safety during the trip.

Frequently Asked Questions about Trekking from Nyenchen Tanglha Mountains to Namtso Lake
Q: Do I need a guide for this route for the first time?
A: A guide is recommended. Local Tibetan guides are familiar with road conditions and weather changes, and can provide help in emergencies. Without a guide, you must have reliable GPS tracks and travel with at least one companion. Guide fees are generally 300 to 600 CNY per day, depending on peak/off-peak seasons and route length.
Q: What physical preparation is needed before trekking?
A: Start training two to three months in advance, doing aerobic exercise two to three times a week, such as running, stair climbing and swimming. Practice leg strength; squats and lunges are effective. It is best to train with a trekking bag in low-altitude mountainous areas several times to adapt to weight-bearing walking. Start with a 5-kilogram load and gradually increase to about 15 kilograms.
Q: Where can I stay near Namtso Lake?
A: There are simple prefabricated houses and tent hotels on Zhaxi Peninsula with basic conditions but beds and quilts. Beds are in short supply and prices rise in peak seasons. If camping by yourself, do not camp too close to the lake due to strong night winds; choose a sheltered spot. There are several relatively flat camps near Zhaxi Peninsula, but confirm camping permission in advance.
Q: How much cash should I bring?
A: Mobile payment is supported in Lhasa and Damxung County, but there are no payment facilities after reaching the trekking start. Prepare a small amount of cash, especially as remote herdsmen’s tents or temporary stalls only accept cash. It is recommended to bring 500 to 1,000 CNY in small denominations for convenience.
Q: Can I trek alone?
A: It is not recommended. High-altitude trekking is risky, and it is difficult to handle altitude sickness or injury alone. It is recommended to travel with at least two people, preferably with a guide. If you must trek alone, inform your family or travel agency of your itinerary in advance and carry a satellite phone or satellite positioning device.
