Himalayan range is abode of many of world’s high altitude lakes, many of these high altitude glacial lakes fall in India. World’s 14th highest lake and India’s highest lake is Cholamu lake.A mighty  elevation of 18000 feet from the sea level takes Cholamu lake to the top of the “highest lakes” list . While coming down the slope around 300 feet from Donkiala pass ( 18300 feet ) , one gets the first glimpses of this rather moderately sized , almost frozen lake.

 Donkiala pass is the north most Sikkim route which leads to Tibet border, which is just 5 kms from Donkiala pass.  This special geographical location of Cholamu lake makes it special and also makes it a very sensitive army area with Chinese army always putting pressure on international borders.

Cholamu lake and Gurudongmar lake are connected by road (9 KM)

Cholamu lake being just 5 – 6 kms  away  from the Tibet border , is nearly off limits for commonplace tourists . One needs special permits, from Army and Sikkim police/administration to visit Cholamu lake. A normal tourist permit will only be issued to visit Cholamu Lake only when one has Army’s permit in place. Normally foreign nationals are not allowed to visit north most areas of Sikkim (this is unlike ladakh where both foreign nationals and Indians are allowed to visit tso Moriri Lake which shares its borders with China). Only Indians can get these special permits to visit two of the highest lakes in India that falls in this region, Cholamu Lake and Gurudongmar Lake.

 Getting permit for  Cholamu lake :

If you are on a family trip with your beloved wife and kids, forget visiting Cholamu Lake , better opt for Gurudongmar lake ,if weather permits, for which one can get permit rather easily . Almost no travel agency will risk their vehicle and driver in this treacherous terrain, that is why if you ask them to arrange a permit for Cholamu lake , they will simply deny going there or at worse they will suggest you it is impossible to get the permit .

Reaching Cholamu lake

Best time to visit Cholamu lake is October and November, one can expect clear sky during this season of the year. Visiting Cholamu lake just after the monsoons is not a good idea if you are planning to visit this lake on your bike. By that time most of the roads would be washed away with rains, and Border road organization (BRO) must be busy patching up the road as fast as they can during this time period.

The journey starts from Gangtok , state capital of Sikkim , one can reach Gangtok from NJP or Siligudi ,these are the nearest railway station . Nearest airport is Bagdogra (Siligudi). 

Gangtok (4,715 ft)  ------ 66 KM ---> Mangan  (3950 ft) -----34 KM ----> Chungthang  (5600 feet)

Till chungthang  the route is same for both,if you are planning to trek up to the lake or ride your thunderbird to Cholamu lake.

IF you are on your vehicle then head towards Lachen

Chungthang  (5600 feet)  ----- 22KM  ---> Lachen  (9,800 ft) ----- 30KM - ---->  Thangu   (13000ft) ----- 40 KM  --> Cholamu lake  (18000 feet)

 If you are trekking with your team then head towards Lachung

Chungthang ---- 25 KM-- > Lachung  (9,600 ft) ----25 KM -- -> Yumthang Valley (11,800 ft)  ---- 32 KM  -->Zero Point (zadong) / Yumesamdong  (16000 ft) (trek starts from this point) ------- ---> Donkaiala pass - --- -> Cholamu lake ( 18000 feet )

 Facts about Cholamu lake

  1. Cholamu lake is India’s highest lake and world’s 14th Highest lake.
  2. Cholamu lake is very near to Gurudongmar lake (45 Mins drive).
  3. Maximum depth of the lake is around 5.5 meters or  18.3 feet .
  4. Many people  believe that  Cholamu lake is the source of river Teesta , which is not entirely true,actually river Teesta originates from a smaller glacial lake Khangchung  (some 100 – 200 feet farther from Cholamu lake ) .
  5. British botanists and explorersof the 19th century Joseph Dalton Hooker mentions cholamu lake in his “Himalayan Journals” about his 7th November 1849 survey of Lachen Valley

"Beyond this I recognised a hill of which I had taken bearings from Donkia pass, and a few miles further, on rounding a great spur of Kinchinjunga, I arrived in sight of Cholamoo lakes, with the Donkia mountain rearing its stupendous precipices of rock and ice on the east. My pony was knocked up, and I felt very giddy from the exertion and elevation; I had broken his bridle, and so led him on by my plaid for the last few miles to the banks of the lake; and there, with the pleasant sound of the waters rippling at my feet, I yielded for a few moments to those emotions of gratified ambition which, being unalloyed by selfish considerations for the future; become springs of happiness during the remainder of one’s life. The landscape about Cholamoo lakes was simple in its elements, stern and solemn; and though my solitary situation rendered it doubly impressive to me, I doubt whether the world contains any scene with more sublime associations than this calm sheet of water, 17,000 feet above the sea, with the shadows of mountains 22,000 to 24,000 feet high, sleeping on its bosom. "

Frozen Cholamu lake

      6.  Cholamu Lake should not be confused with Oracle Lake ( Lhamo la-tso) (17,388 ft) , Lhamo latso is situated in Tibet near Lhasa.

Chances to see snow are high

Chances to see snow are high around Gurudongmar Lake and Yumthang valley in second week of May. I am not sure if its flowering season in Yumthang. Autumn and Spring are generally very coloful in the valley. Unfortunately North Sikkim is not entirely open for tourists. Most of the places are out of bound for tourists so you can not go beyond places you already visited.

Hi Vishnu,


Great article!


I am planning to visit Sikkim during 20-26 March. It'd be great if you could answer a few queries I have pertaining to his.


1. Can these 2 lakes be visited during this period?

2. What about Nathu La pass, Pelling and Zero point? Would these roads be open during this time?

3. Is the RAP needed if we decide to trek to Cholamu Lake from Zadong? Also, is this a day-trek?


TIA. Cheers.

Cholamu is out of bound but

Cholamu is out of bound but tourists but Gurudongmar can be visited in March this year as there is not much snow.

Yes, Nathula, Zero point and Pelling would also be accessible.

Hey Vishnu

Let me first thank you for replying to everyone's query very patiently. I really appreciate it.

I along with my family (including parents who are above 60) is planning to visit Sikkim in mid/end May and have decided to visit Namchi, pelling and Gangtok. I am really fascinated to visit Lachen and Gurudongmar lake. I have few queries in this regard.

1. How advisable will be it to travel to Gurudongmar lake along with elderly people and kids (1 year to 5 years)?

2. What is the average temperature during mid/end May?

3. Do we need any permit for Lachen or Gurudongmar lake?

4. Do we need to trek for Gurudongmar lake? If yes, how long and how harsh is the trek?

5. Any other information I need to know.

Thanks in advance.

I think kids below 4 would

I think kids below 4 would not be allowed to Gurudongmar but there is no problem visiting with elder people. Be mindful that Gurudongmar is really high altitude and people get hit by AMS. if your parents are having any health issue then there is no point.

May is hot month. can not comment on temperature.

Yes, you will need permit and can be procured very easily in Gangtok.

There is no trek for Gurudongmar lake. Vehicles go till the lake bed.

Enjoy the captivating landscape.

Hi Anurag, While looking at

Hi Anurag,

While looking at your itinerary i do not see any space where you can add pelling. Darjeeling has its own charm so i would not recommend to skip Darjeeling over Pelling. May is not the best time to see snow but you can find it near Gurudongmar lake, Yumthang and Nathula pass.  Yes, ILP would be needed and you can obtain it from Gangtok.

Hi Vishnu,   Thank you for

Hi Vishnu,


Thank you for providing invaluable info throughout.

I am reaching siliguri by Dec 18th evening around 7 PM. 

My plan is to reach lachen the same night (is it possible?) and visit thange, gurudongmar lake, zero point the next day (not sure if it is possible in one day).

And to take bus from gangtok the day after to phuentsholing at the earliest as im planning to visit Bhutan as well.

To summarize, after reaching siliguri on dec 18th (7 PM) i want to visit the places around lanchen, going to bhutan from gangtok and get back to Siliguri on 24th Dec to catch my train. (6 nights and 5 days)


Please let me know the below details.

1. Permissions to get and procedures. (around Lachen and entering sikkim).

2. Travelling charge in bus and hird-taxi (not shared) to reach lanchen and day-trip.

3. Bus and booking details from gangtk to bhutan (phuentsholing).

4. is it possible to stay in monastry in lachen?

Im sorry if too much is asked. As Im visiting with my girlfriend, I just want to have all possible info.

If you prefer any hotels and travels, please send the details as well.


Thank you so much. Hooping to get your reply soon


If you are reaching Siliguri

If you are reaching Siliguri in evening then it is not possible to reach Lachen on the same day. i do not think you will get a taxi guy ready to drive to Lachen in night. Even reaching Gangtok will be difficult.

6 nights/5 days are very less to visit Sikkim and Bhutan. Even 6 days are not sufficient for a comprehensive trip to Sikkim...

Permits are issued from Gangotk. you can get it on the same day.

I do not know the current quotation of package.

I have no clue about staying in Monastery in Lachen. nevertheless there are plenty of accommodation options.
