Are you planning a trip to Gurudongmar Lake and Chopta Valley in North Sikkim? If you have ever visited high altitude lakes like Pangong Tso, Chandratal, or Tso Moriri, you already know how magical these landscapes can be. For those who have not, let me tell you, no amount of photos or descriptions can truly capture what your eyes witness at 17,800 ft. It is simply magical.
Gurudongmar Lake is one of the highest lakes in the world, sitting in North Sikkim near the Indo-China border. The first time I laid my eyes on Gurudongmar, I was mesmerized at the various shades of water, snow-capped cliffs forming a natural barrier around the lake, creating a surreal beauty. A monk takes care of a small monastery next to the lake. I envy him because he is privy to this paradise on earth. However, I do not envy the cold he has to bear, which is worsened by the constant winds. In this guide, I will cover everything you need to know to plan your trip to Gurudongmar Lake and Chopta Valley in 2026, including permits, costs, how to reach, best time to visit, and where to stay.

How to Reach Gurudongmar Lake from Gangtok?
There is no public transport to Gurudongmar Lake and hiring a taxi through a registered travel agent is the only option. The route goes from Gangtok to Mangan to Lachen, where you stay overnight, and then from Lachen to Thangu to Gurudongmar Lake the next day. Keep in mind, individual self-drive vehicles are generally not allowed on this route due to the sensitive border area. You must travel with a registered tour operator who arranges your permits, vehicle, and driver.
By Road
- Day 1: Gangtok to Lachen (about 130 km, 6-7 hours). Overnight at Lachen.
- Day 2: Lachen to Thangu (35 km, about 1.5 hours) to Gurudongmar Lake (32 km, about 2.5 hours). Return to Lachen or proceed to Lachung.
On the day you visit the lake, try leaving early, around 3:30 AM to 4 AM. Have only tea or light snacks and proceed to Thangu. You can have breakfast at Thangu around 6 AM to 7 AM and then proceed towards Gurudongmar. The idea is to reach the lake by 9:30 AM to 10 AM and start your return by noon. The weather near Gurudongmar usually turns unpredictable after midday, so an early start is not optional, it is essential.
What Is the Road Like from Lachen to Gurudongmar?
The roads leading to Gurudongmar Lake were virtually non-existent until a few years ago. However, now there are smooth roads once you cross the Giagong Army checkpost at an altitude of about 15,000 ft. After that, the road becomes rough, stony, and runs over moraines. In winter and early spring, sections can be snow-covered and slippery. The journey itself is worth the effort. A vastness which seemingly spreads across the horizon, alpine pasture lands where yaks and blue sheep lazily graze around, local folks churning yak milk into cheese in their homes, the absence of human influence will make you want to live there permanently, leading a simple life like that of nomads.
By Air
The nearest airport is Bagdogra Airport (IXB) near Siliguri in West Bengal, about 280 km from Gangtok. From Bagdogra, you can take a shared taxi or hire a private cab to Gangtok (about 4-5 hours). Alternatively, Pakyong Airport near Gangtok operates limited flights, but flight availability is inconsistent, so Bagdogra remains the more reliable option. You can check this article on how to reach Gangtok and other important info for detailed directions.
What Permits Do You Need for Gurudongmar Lake?
Since Gurudongmar Lake is close to an international border, foreign nationals cannot visit the lake. Only Indian citizens are allowed, and you need a Protected Area Permit (PAP) to visit. Here is what you should know about the permits.
- Who can apply: Only Indian nationals. Foreigners can go up to Chopta Valley but not Gurudongmar Lake.
- How to get it: Through a Sikkim Tourism registered travel agent in Gangtok. The permit is processed through the Tourism Department and the Police checkpost.
- Documents needed: Aadhaar Card, Voter ID, Driving License, or Passport. Two passport-size photos. Duly filled permit application form.
- Cost: The permit itself is free of cost. However, the registered travel agent charges a service fee since they are liable for your safety during the trip.
- Processing time: Usually processed within a day. I suggest getting your permit arranged at least one day before heading to North Sikkim.
- Children restriction: Children below 5 years are officially not permitted to visit high-altitude areas like Gurudongmar Lake. Permit authorities may check the age of the child.
Your Inner Line Permit will be checked at the Giagong Army checkpost. You need to cross the checkpoint between 7:30 AM and 10:30 AM in the morning. You also need to exit by 12:30 PM as the weather turns unpredictable here. The small Army shelter provides everyone with free piping hot tea and coffee, which is much needed in that cold. There is a small souvenir section run by the Army selling coffee mugs, holy water from the lake, and more. Please support our army by buying from there! You have restrooms too in the premises for public use.
What Is the Best Time to Visit Gurudongmar Lake?
The best time to visit Gurudongmar Lake depends on what kind of experience you are looking for. Here is a month-wise breakdown to help you decide.
- April to June (Spring/Summer): This is the most popular window. The ice starts melting, the lake shows its beautiful shades of blue and turquoise, and the roads are generally accessible. Temperatures are relatively milder (though still cold), ranging from -5 to 10 degrees Celsius. If this is your first visit, I suggest planning in May or June.
- July to September (Monsoon): Not recommended. Heavy rainfall can cause landslides on the Gangtok to Lachen road. The road to Gurudongmar may be blocked for days. Permits may also be restricted during this period.
- October to November (Autumn): Clear skies, excellent visibility, and the lake starts freezing partially. This is a great window for photography. However, temperatures drop to -10 to -15 degrees Celsius, so be prepared with proper winter gear.
- December to March (Winter): The lake is completely frozen and often covered in snow. The road may be closed due to heavy snowfall. Only experienced travelers should attempt this, and even then, access is not guaranteed.
According to local legend, Guru Rinpoche blessed a portion of the lake, which supposedly never freezes completely, even in the harshest winters. This ensures water supply to the nearby villagers year-round. Whether you believe the legend or not, the partially unfrozen section amidst a fully frozen landscape is a sight to behold.
What About AMS (Acute Mountain Sickness) at Gurudongmar?
At 17,800 ft, Gurudongmar Lake is at a very high altitude and AMS is a real concern. The oxygen level drops significantly at this height, and your body may not respond well if you rush to the lake without proper acclimatization. I have covered the principles of AMS and acclimatization in detail in a separate article. I strongly recommend you read about Acute Mountain Sickness and the importance of acclimatization before planning this trip.
Safety Warning: Gurudongmar Lake is at a very high altitude. You could be hit by AMS if you over-exert yourself. It is advised to reach the lake early before noon and not stay for longer durations. Do not run or jump around at the lake. Keep your movements slow and deliberate. If you experience severe headache, nausea, vomiting, or disorientation, descend immediately to a lower altitude.
Here are some practical tips to minimize AMS risk:
- Spend at least one night in Lachen (about 8,800 ft) before proceeding to Gurudongmar. This gives your body time to acclimatize.
- Stay hydrated. Drink plenty of water and avoid alcohol completely.
- Eat light meals before the journey. Heavy food can worsen AMS symptoms.
- Carry Diamox (acetazolamide) after consulting your doctor before the trip.
- Carry a portable oxygen cylinder, just in case. Some tour operators provide one in the vehicle.
- Do not stay at the lake for more than 30-45 minutes.
What Is Chopta Valley and Why Should You Visit?
On your return journey from Gurudongmar, take a detour to reach Chopta Valley. Now, there are numerous Chopta valleys in the Himalayas (Uttarakhand has a famous one too), but this Chopta Valley in Sikkim is above Thangu village at an altitude of about 13,000 ft. A mud-track road runs parallel to the valley and you can travel for a few kilometres to see it stretching far.
The vegetation is noticeably different due to the high altitude, and the contrast is striking. Meandering streams criss-cross all over the valley floor. Rhododendrons are scattered everywhere, birds are calling, and the valley is a hotspot during the birding season (April to May). If you are into birdwatching, this is a place you should not miss. Park your vehicle and walk down the mud track to spend a couple of hours here on your way back from Gurudongmar. Take a stroll along the river or simply sit on the rocky beds and soak in the view.
Important: Foreigners can visit Chopta Valley even though they cannot go to Gurudongmar Lake. So if you are traveling with foreign friends, they can enjoy Chopta Valley while you proceed to the lake.
How Much Does a Trip to Gurudongmar Lake Cost in 2026?
Here is a rough budget breakdown for a Gurudongmar Lake and North Sikkim trip as of 2026. These numbers are for one person and can vary depending on the season and your travel style.
| Expense | Budget (INR) | Mid-Range (INR) |

| Bagdogra to Gangtok (shared taxi) | Rs 300 – 500 | Rs 3,000 – 4,000 (private) |
If you opt for a complete package (3 days, 2 nights, shared basis), expect to pay around Rs 4,000 to 5,000 per person in the off-season and up to Rs 6,000 to 8,000 per person during peak season (October/November). A 5-day package covering Lachen, Gurudongmar, Lachung, and Yumthang Valley ranges from about Rs 10,000 to 13,000 per person on a sharing basis, as per rates listed on the Sikkim Tourism official portal.
Overall, a 7-day North Sikkim trip covering Gangtok, Lachen, Gurudongmar Lake, Lachung, and Zero Point can range from Rs 25,000 to 40,000 per person, including transport, accommodation, food, and permits. If you are on a tight budget, traveling in a group of 4 helps bring costs down significantly since taxi fares are split.
Where to Stay Near Gurudongmar Lake?
You need to keep Lachen or Thangu as your base while visiting Gurudongmar and Chopta. Lachen is the preferred option due to better facilities. Here are your options.
Accommodation in Lachen
- Delight Royal, Lachen: Has a wonderful view of snow-clad mountains right from its doorsteps. Rooms are spacious enough but basic considering the remoteness of the village. Expect to pay around Rs 1,500 to 3,000 per night depending on the season.
- Hotel Blue Pine, Lachen: A budget range hotel with basic rooms and good views. They can be reached at +91 8348903404 or +91 7585919875. Rates start around Rs 800 to 1,500 per night.
- Several other homestays and guesthouses have come up in Lachen in recent years. Most tour operators include accommodation in their package, so you may not need to book separately.
Accommodation in Thangu
There are limited options available in Thangu. Most of them are very basic, not very comfortable, and may not be suitable for kids or elderly. Thangu village at an altitude of 14,000 ft has an average temperature of 5 to 10 degrees even during summer months. Please take necessary precaution if you plan to stay at Thangu, especially during winters as it experiences heavy snowfall.
- Tshetenla Lodge, Thangu: They can be reached at +91 9434867312. Very basic but functional.
- Kunga Restaurant, Dragon Lodge & Restaurant: These are sort of rustic homestays in Thangu. Do not expect hotel-like amenities here.
What Should You Pack for Gurudongmar Lake?
Packing right is critical for a trip to Gurudongmar. The temperature at 17,800 ft can drop to -15 degrees Celsius or lower, even in May. Here is a checklist.
- Heavy down jacket and multiple warm layers (thermals are a must)
- Woolen cap, gloves, muffler, and earmuffs
- Good quality trekking shoes with grip (the terrain near the lake is rocky and may be icy)
- Sunglasses with UV protection (snow glare can damage your eyes)
- Sunscreen with high SPF (the UV radiation at this altitude is intense)
- Personal medicines, Diamox (consult your doctor), and basic first-aid
- Portable oxygen cylinder (optional but recommended for first-timers)
- Water bottles and dry snacks (there are no shops between Thangu and Gurudongmar)
- Power bank (your phone battery drains faster in cold temperatures)
- Original ID proof (Aadhaar/Voter ID/Passport for permit verification at checkpost)
Is There Mobile Network at Gurudongmar Lake?
In short, no. Mobile network connectivity is non-existent beyond Lachen. You may get intermittent signal in Lachen itself (BSNL has the best chance), but once you leave for Thangu and Gurudongmar, expect zero connectivity. Hence, inform your family in advance about your plans and the expected time you will be unreachable. Most hotels in Lachen have landline phones that you can use in case of emergencies.
What Else Can You Explore in North Sikkim?
A trip to Gurudongmar Lake is usually part of a larger North Sikkim itinerary. Here are some places you can club together.
- Lachung and Yumthang Valley: Often combined in a 4-5 day North Sikkim package. Yumthang is known as the “Valley of Flowers” and is stunning in April-May.
- Zero Point (Yumesamdong): At about 15,300 ft, this is the last civilian point in North Sikkim towards the China border. Accessible from Lachung.
- Gangtok and Nathu La: Most North Sikkim trips begin and end in Gangtok. If you have a day to spare, a visit to Nathu La Pass and Gangtok sightseeing is well worth it.
- Zuluk (Silk Route): If you have extra days, the Zuluk Silk Route in East Sikkim offers incredible views and is an offbeat addition to your Sikkim trip.
- Pelling: In West Sikkim, Pelling offers views of Kanchenjunga and ancient monasteries.
- East Sikkim Silk Route: For those wanting to explore further, check out the Old Silk Route in East Sikkim.
Important Tips for Your Gurudongmar Lake Trip
- Travel only through registered agents: Self-drive is generally not allowed on the North Sikkim route. You need a registered operator for permits and logistics.
- Start early, very early: Leave Lachen by 3:30 AM to 4 AM. The weather window at Gurudongmar is narrow.
- Do not overexert at the lake: Walk slowly, breathe deeply, and do not stay for more than 30-45 minutes.
- Carry cash: There are no ATMs after Mangan. Withdraw enough cash in Gangtok or Mangan for your entire North Sikkim leg.
- Carry your own water and snacks: There are no shops between Thangu and Gurudongmar (about 32 km of nothingness).
- Support the Army: At Giagong checkpost, the Army runs a small souvenir shop and provides free hot tea. Consider buying something from them as a gesture of support.
- Plan for weather changes: Weather at this altitude can change within minutes. Keep rain gear and warm layers accessible, not buried in your bag.
- Respect the environment: Gurudongmar is a sacred lake for both Buddhists and Sikhs. Do not litter, do not play loud music, and carry your waste back with you.

Is Gurudongmar Lake safe for kids and elderly?

A minimum of 3 days and 2 nights is needed. Day 1: Gangtok to Lachen, Day 2: Lachen to Gurudongmar and back, Day 3: Lachen to Gangtok. If you want to include Lachung and Yumthang Valley, plan for 5-6 days from Gangtok.
Does Gurudongmar Lake freeze completely in winter?
The lake freezes almost completely from November to mid-May. However, according to local legend, a portion blessed by Guru Rinpoche never freezes, even in the harshest winters. This unfrozen section provides water to nearby communities year-round.
What is the best month to see the blue water of Gurudongmar?
May and June are the best months to see the lake in its full blue and turquoise glory. The ice melts, the water shows stunning color gradients, and the weather is relatively manageable compared to other months.

Hi Lakshmi, Did you travel alone? Do you think its safe for a single female traveler to use a personal taxi to get from Gangtok to Lachen to Gurudongmar? I will be traveling next week, and I am not sure if getting a personal taxi is safe since the distances are long and maybe not all that populated.
Hi Surabhi,
I did not travel alone. Did you try posting your travel plan in DoW Travel Partners Calendar? (https://discoverwithdheeraj.com/dow-travel-partners-calendar/) Try to see if you get like-minded people travelling around the same time.
Yes the routes are long and less populated, but from my personal experience I have not seen drivers or hotel owners behave badly to tourists. It usually is the other way around. Not to discourage you, but have you traveled solo before?
