Dzongri and Goecha La are the two goals of Sikkim's best-known trek, which starts at Yuksom and climbs through Khangchendzonga National Park. Dzongri, a meadow at about 4,020 m, takes 5–6 days return. The Goecha La viewpoint, at about 4,570 m facing Kangchenjunga, takes 9 walking days. A registered agency, licensed guide and park permit are required.

The trail leaves the top of Yuksom (1,780 m) and follows the Prek Chu valley north into Khangchendzonga National Park. It climbs through warm broadleaf forest to Sachen, then through oak, magnolia and rhododendron past Bakhim to Tshoka at about 3,000 m, and on through Phedang to the open meadows of Dzongri at about 4,020 m. The Sikkim Forest Department describes the full route to Goecha La as about 45 km.
Dzongri is where the short trek ends. A pre-dawn climb to Dzongri Top, at about 4,200 m, gives sunrise on Kabru, Rathong, Kangchenjunga and Pandim. The long trek continues to Thansing and Lamuney, passes Samiti Lake in the dark and climbs to the first viewpoint below Goecha La, at about 4,570 m by the Forest Department's figure, directly facing the south-east face of Kangchenjunga (8,586 m). That is a full day of 10–12 hours on foot.
The pass itself, given as 4,940 m on Wikipedia, and the higher viewpoints are closed to protect the alpine zone. No one treks here alone: rules require a registered Sikkim trekking agency, a licensed guide and park permits, and foreigners need a Protected Area Permit in a group of two or more. The seasons are April to mid-May for rhododendrons and late September to November for clear views. We do not run treks in the June–August monsoon.
Highlights
What to see and do
Sunrise from Dzongri Top
From the Dzongri camp, a pre-dawn climb of about an hour reaches Dzongri Top at around 4,200 m. As the sun rises, Kabru, Rathong, Kangchenjunga and Pandim light up in a line across the north. Cloud often lifts briefly after sunrise, so be patient.
The rhododendron belt
Between Bakhim and Phedang the trail climbs through forest dense with rhododendron trees. From April to mid-May they flower red, pink and white, with magnolias lower down. It is the reason many trekkers choose the spring season over autumn's clearer skies.
Samiti Lake at dawn
On the summit-day start from Lamuney, the trail passes Samiti Lake, sacred to Bhutia and Lepcha communities. On the way back in daylight, Pandim often reflects in the still water. No camping is allowed at the lake.
Face to face with Kangchenjunga
The first viewpoint below Goecha La, at about 4,570 m, looks straight at the south-east face of Kangchenjunga. Groups reach it around sunrise after a 3 am start, spend a short time and walk back to Thansing.
Forest, meadow and moraine in one trek
In under a week you walk from subtropical forest above the Prek Chu through oak and fir, rhododendron and juniper, to open alpine meadows and glacial moraine. It is the clearest way to see how Sikkim's altitude shapes its landscape.
A trail run by local teams
Guides, cooks, porters and pack animal handlers on this trail mostly come from Yuksom and nearby villages. Choosing a registered local team keeps the money in the valley and gives you people who know every bend and campsite.
The story of Dzongri and Goecha La
The summit that climbers leave untouched
The mountain at the end of this trail has a climbing history shaped by respect. Wikipedia's article on Kangchenjunga records that when Joe Brown and George Band made the first ascent on 25 May 1955, from the Nepal side, they stopped just short of the true summit. They were keeping a promise given to Tashi Namgyal, the Chogyal of Sikkim, that the top of the mountain would remain inviolate, because Kangchenjunga is worshipped in Sikkim as Dzö-nga, the guardian deity of the land. The same article notes that the Indian side of the mountain is off limits to climbers. The peaks you see from Dzongri Top have their own stories. Wikipedia notes that in 1883 the British climber William Woodman Graham and two Swiss mountaineers reported reaching within 30–40 ft of the summit of Kabru, and that in 1907 two Norwegians came within 50–60 ft before strong winds turned them back. Standing at Dzongri at sunrise, with Kabru and Kangchenjunga turning gold, you can see why the Chogyal asked for that promise.

To reach the trailhead, take a shared jeep from Siliguri or Gangtok to Gyalshing or Jorethang, then a local jeep to Yuksom, indicatively ₹500–900 in total and a long day. Many agencies offer shared transport from NJP to Yuksom for about ₹2,000–3,500 return per person.
Private car
From Pelling to Yuksom, about 40 km and 2 hours, indicatively ₹2,500–3,500 one way. From Gangtok, about 150 km and 6.5–7.5 hours. Beyond Yuksom there is no road: the trek is on foot, with pack animals or porters carrying the loads.
From Bagdogra / NJP
About 170 km and 6.5–7.5 hours to Yuksom via Melli, Jorethang, Legship and Tashiding, indicatively ₹6,500–8,500 by private car. Arrive the day before the trek starts. NH10 closes after heavy rain; the alternative is via Darjeeling. Check current status before you travel.
Permits in West Sikkim
Indian travellers need no permit for Pelling, Yuksom, Khecheopalri, Tashiding or Uttarey. The Dzongri and Goecha La trek needs a Khangchendzonga National Park permit and fees, arranged at Yuksom through a registered trekking agency with a licensed guide. Foreign nationals need the Restricted Area Permit to enter Sikkim, applied for online via the e-FRRO portal after arriving in India, and a Protected Area Permit in a group of two or more for the Dzongri–Goecha La trek. Sikkim charges a ₹50 per tourist fee at check-in. Check current status before you travel.
On the trail, groups sleep in tents at designated campsites at Sachen, Tshoka, Dzongri, Thansing and Lamuney; the Forest Department also runs basic trekkers' huts at Tshoka, Dzongri and Thansing, though in season most groups camp. Your first and last nights are in Yuksom, where Yuksum Residency and Hotel Tashigang are practical value hotels and village homestays cost about ₹1,200–2,200 per person with meals. Book Yuksom early for October and April–May, when trekking groups fill rooms.
Keep the rest day at Dzongri; it is the most important acclimatisation day of the trek.
Book only with a team registered with Sikkim Tourism; only registered agents can process park permits.
Break in your boots and train for six to eight weeks; aim to walk 10 km with a light pack comfortably.
Carry out all your rubbish; the park checks bags for plastic at Yuksom.
Descend at once if a headache worsens or you feel breathless at rest, and tell your guide.

BestGoodAvoid or closed
Dzongri and Goecha La is at 4,020 m. Spend a night lower down first, climb slowly and drink water. Headache, nausea or breathlessness at rest mean go down. The altitude ladder.
The classic route takes 9 walking days from Yuksom and back, so most trips are 10–11 nights from NJP including the drives. That includes a rest and acclimatisation day at Dzongri. The shorter Dzongri trek takes 5–6 days from Yuksom, about six nights from NJP.
How much does the Goecha La trek cost?
Group departures from Yuksom cost roughly ₹22,000–30,000 per person plus GST, including tents, food, guide, cook and park fees. Add ₹2,000–3,500 for shared transport from NJP and offloading at ₹400–600 a day if you want a porter. A private trek for two costs about ₹45,000–70,000 per person. Figures are indicative for 2026.
Do I need a permit for Dzongri and Goecha La?
Yes. Every trekker needs a Khangchendzonga National Park permit and must register at Yuksom through a registered trekking agency with a licensed guide. Foreign nationals also need Sikkim's Restricted Area Permit via the e-FRRO portal and a Protected Area Permit, issued to groups of two or more. Check current status before you travel.
Can I do the Goecha La trek without a guide?
No. Solo and unguided trekking is not allowed in Khangchendzonga National Park. Every group registers at Yuksom with a registered local guide, and permits are checked on the trail. A guide also matters for safety, since weather above Dzongri changes fast and summit day starts in the dark.
What is the best month for Goecha La?
October and early November give the clearest views of Kangchenjunga and the most stable weather, with very cold nights. April to mid-May is rhododendron season, with milder nights and more afternoon cloud. Avoid June to August, when monsoon rain, leeches and cloud make the trail slippery and views rare.
How difficult is the Goecha La trek?
Moderate to difficult. You climb from 1,780 m to about 4,570 m, walk 5–8 hours on most days and face a 10–12 hour summit day starting around 3 am. Previous trekking helps but is not essential if you train for six to eight weeks and can walk 10 km with a light pack comfortably.
How do I avoid altitude sickness on the Dzongri trek?
Walk slowly, drink 3–4 litres of water a day, eat well, avoid alcohol and keep the rest day at Dzongri. The trail gains about 2,200 m in three days from Yuksom. Tell your guide at once about headache, nausea or breathlessness at rest; descending is the cure for anything worse than mild symptoms.
Where do you sleep on the Goecha La trek?
Mostly in tents at designated campsites at Sachen, Tshoka, Dzongri, Thansing and Lamuney. Tshoka, Dzongri and Thansing also have basic Forest Department trekkers' huts, but in season most groups camp. Your first and last nights are in a Yuksom hotel or homestay.
Can children do the Dzongri trek?
Fit teenagers who walk regularly usually manage the Dzongri trek well with a slow pace. For younger children we do not recommend it, because the trek climbs above 4,000 m in four days and altitude sickness is harder to spot in children. A day walk from Yuksom into the forest is a better family option.
