How the day works
Almost every Lachung tour includes Yumthang Valley on the morning after you arrive. The vehicle that brought you from Gangtok waits at your lodge, and you leave around 6 am, when the sky is clearest and the valley is quiet. The road climbs 24 km along the Lachung Chu through fir and rhododendron forest, about an hour, to the grazing ground of Yumthang at 3,564 m.
If your group has paid for Zero Point, you carry on another 23 km to Yumesamdong, at roughly 4,700 m, which takes 1–1.5 hours more on a rougher road. You spend 30–45 minutes in the snow, come back down through Yumthang, and are at your lodge for a late lunch by 1–2 pm. On a 2-night tour you drive back to Gangtok that afternoon; on a 3-night trip you have the afternoon in Lachung village. The timings below are typical.
| Time | Where | What happens |
|---|---|---|
| 5:30–6:00 am | Lachung lodge | Tea, rent boots and coat if needed, leave |
| 7:00 am | Yumthang | Valley, river, rhododendrons, yaks in season |
| 8:30–9:00 am | Zero Point | Snow, tea stalls, 30–45 minutes |
| 10:30 am | Yumthang | Hot spring, tea and Maggi at stalls |
| 12:00–1:00 pm | Lachung | Lunch, then drive to Gangtok or rest |
Yumthang Valley and the Shingba sanctuary
Yumthang is a broad, flat valley where the Lachung Chu runs between gravel banks and the slopes rise steeply into forest and snow. It lies within the Shingba Rhododendron Sanctuary, and these are the slopes where the botanist Joseph Dalton Hooker collected rhododendron seed in 1849. In winter Yumthang is often under snow. From late April to May it is the reason many people come: the slopes flower red, pink, cream and yellow, from the lower trees upward, and primulas follow on the meadows.
From June the valley is green and Lachung families bring yaks and cattle up to graze; in October and November it turns gold and rust. A natural hot spring by the river has a small bathing shed; people soak their feet or bathe on the way back from Zero Point. There is a short boardwalk and a line of tea stalls by the parking area. Stay on the paths, do not pick flowers, and do not feed the yaks.
Zero Point at Yumesamdong
Yumesamdong is where the civilian road ends, about 23 km above Yumthang at roughly 4,700 m. It is called Zero Point because the road beyond it is for the army. There is no village, only bare slopes, snowfields and, in season, a row of huts selling tea, Maggi and soup. Snow lies here from about November into May and sometimes later, which is why families who have never touched snow pay the extra to come.
Zero Point costs ₹3,000–4,500 extra per vehicle, which works out cheaply per head in a full shared jeep. It is open to Indian nationals only; foreigners with a Protected Area Permit usually go no further than Yumthang. The road is often closed after fresh snow in winter and spring, and since the October 2023 flood the authorities have restricted access at times. Pay on the spot if the road is open, not in advance, and check current status before you travel.
A local planner turns it into a route for your dates.
Altitude and cold
Lachung is at about 2,700 m, Yumthang at 3,564 m and Zero Point at about 4,700 m. That is a climb of 2,000 m in three hours, and some people feel it: headache, breathlessness, nausea or dizziness. Move slowly in the snow, do not run or throw snowballs hard, drink warm water, and keep children close. If anyone feels unwell at Zero Point, go down at once; symptoms usually ease by Yumthang.
Even in May, Zero Point can be well below freezing with a cold wind. Rent knee-high snow boots and a long padded coat in Lachung for ₹100–300 each; they are worth it. Add gloves, a woollen cap and sunglasses, because snow glare at this height burns eyes and skin quickly. Carry sunscreen and lip balm.
If you are coming to Lachung from Lachen after Gurudongmar the day before, your body has already had one hard day at altitude. Many people feel tired and short of sleep by the Yumthang morning. That is a good reason to make Zero Point a choice on the day rather than a fixed plan, and to let anyone who is struggling rest in Yumthang while the others go higher.

Plans for every kind of group
Not everyone in a vehicle wants the same day, and in a shared jeep you have to agree. These are the versions we suggest to different groups, all starting from a Lachung lodge.
For families with small children or older parents, Yumthang alone is enough. Leave at 6:30 am, spend an hour in the valley and at the hot spring, and be back in Lachung for breakfast and a slow morning. Zero Point adds a big altitude jump and two more hours in the car for a short time in the snow. If others in the jeep want to go higher, they can drop you at the Yumthang stalls and collect you on the way down; agree this with the driver beforehand.
For snow-seekers, go straight to Zero Point first while the road is firm and the sky clear, then stop in Yumthang on the way down. This order also means you spend less time at the highest point after a big breakfast. For photographers, two nights in Lachung let you do Yumthang at first light on one day and Zero Point on the next, with Lachung's orchards and monastery in the evening light between.
For foreign nationals, Yumthang is usually the end of the road. Make the most of it: walk the river flats toward the forest, look for yaks and Himalayan birds, and spend time at the hot spring. Agents may also offer a short side trip to a waterfall or the village monastery in place of Zero Point.
Making the most of it
A few choices make the day better. Book two nights in Lachung rather than one, so you do Yumthang and Zero Point unhurried and still see Lachung Monastery, founded in 1880, and the apple orchards. For flowers, aim for the first three weeks of May; for snow on the valley floor, late March and early April; for clear skies and autumn colour, October and early November.
Some agents also sell Katao, a separate snow area on another branch above Lachung. Access to Katao has opened and closed over the years, so ask whether it is permitted that week. The road from Gangtok to Lachung runs through the Teesta valley and Chungthang, which have had repeated closures since 2023. Keep a buffer day, carry cash, and check current status before you travel.
Questions people ask
Good to know
How far is Yumthang from Lachung?
About 24 km, roughly an hour by road along the Lachung Chu. Zero Point at Yumesamdong is about 23 km further, another 1–1.5 hours. Most tours leave Lachung at 6 am, visit both and are back for lunch by 1–2 pm. Road conditions after snow or landslides can change this; check current status before you travel.
When is the best time to see rhododendrons at Yumthang?
Late April to the end of May, with the fullest bloom usually in the first three weeks of May. The Shingba Rhododendron Sanctuary flowers from lower slopes upward, so early in the season you see flowers below and snow above. Primulas follow on the meadows. A cold spring can push the bloom later.
How much does Zero Point cost?
About ₹3,000–4,500 extra per vehicle on top of a Lachung tour, so ₹400–600 per person in a full shared jeep of eight. Prices rise in peak weeks. Agree to pay on the spot if the road is open, because snow or restrictions close it at short notice. Indian nationals only.
Can foreigners go to Zero Point?
Usually not. Foreign nationals with a Protected Area Permit have generally been allowed to Lachung and Yumthang Valley but not to Zero Point at Yumesamdong, which lies close to the border. The rules change, so ask your registered agent and check current status before you travel.
Is there snow at Zero Point in May?
Usually yes. Snow lies at Yumesamdong, about 4,700 m, from roughly November into May and sometimes into June. Yumthang itself is mostly free of snow by May, when the rhododendrons flower. If snow is your main goal, March and April give snow at both places.
Is Zero Point safe for children and older people?
It is a large altitude jump, from 2,700 m to about 4,700 m in three hours. Many healthy children and older people manage a short visit, but headaches and breathlessness are common. Avoid running, keep the stop to 30–45 minutes, and go down at once if anyone feels unwell. People with heart or lung conditions should ask a doctor first.
Is there a hot spring at Yumthang?
Yes, a natural hot spring beside the Lachung Chu in Yumthang Valley, with a simple bathing shed. People soak their feet or bathe on the way back from Zero Point. It is free. Bring a small towel, and keep your stay short if you have been feeling the altitude.
Do I need to rent boots and a coat for Yumthang?
For Zero Point, yes, in almost every season; for Yumthang, from October to April. Shops in Lachung rent knee-high snow boots and long padded coats for ₹100–300 each a day, cheaper than buying in Gangtok. Your driver will stop at a rental shop before leaving.
Is Yumthang open after the 2023 flood?
Yumthang and Lachung have generally reopened more often than Lachen and Gurudongmar since the October 2023 Teesta flood, but the road through Chungthang has closed repeatedly after landslides, especially in the monsoon. Ask two Gangtok agents what is open that week and check current status before you travel.
