Goecha La - Kasturi La Circuit Trek

The Goecha La - Kasturi La Circuit is a 12-day private loop in West Sikkim. It climbs the Goecha La trail from Yuksom and comes home by a different way, so you never walk the same ground twice.

From Yuksom you climb through forest to Tshoka and Dzongri, and wake early for sunrise on the Kanchenjunga massif from Dzongri Top. The Prek Chu valley leads on to the open camp at Thansing, under Pandim, Tenchenkhang and the Kabru group, with a dawn walk to the Goecha La viewpoint and Samity Lake. Then the circuit leaves the usual path for Chamrey and Lampokhari Lake, crosses Kasturi La, and drops through rhododendron and silver fir forest to the Gurung village of Labdang, near Tashiding.

It is a trek for fit walkers who want the Goecha La trail and a loop in one trip. You start with a day in Yuksom, Sikkim's first capital, and walk into Khangchendzonga National Park on day 3. The days after are long, with steep ascents and descents, rocky moraine and stone steps. The camps are remote. In return you get a quieter loop than the out-and-back Goecha La trek, and you never retrace your steps.

• Duration: 12 days, 11 nights, Bagdogra to Bagdogra, including one flexible reserve day at Chamrey
• Highest point: 4,300 m, Dzongri Top
• Grade: Strenuous; most days 5 - 8 hours, a few longer
• Best months: March to May and September to December

Your group is private, and acclimatisation is built into the days: a full day at Dzongri, and a reserve day by Lampokhari Lake.

• Yuksom, Sikkim's first capital: A full day before the trek visits Dubdi Monastery, the Norbugang coronation throne (where the first Chogyal was crowned in 1642) and Kathok Lake.
• Dzongri Top at sunrise: A pre-dawn climb to 4,300 m puts the Kanchenjunga massif in the first light, with more than ten snow peaks to pick out.
• Dzongri La: The pass is crossed on the same rest-and-acclimatise day, with views over the Oklathang valley and Rathong glacier before you return to camp.
• Thansing camp: A wide, open camp in the Prek Chu valley, ringed by Pandim, Tenchenkhang, the Kabru group and Kanchenjunga.
• Goecha La viewpoint and Samity Lake: An early start for sunrise at the viewpoint, then quiet time by Samity Lake, and back at Thansing by noon.
• Lampokhari Lake: Camp at Chamrey and spend a reserve day among the high lakes around Lampokhari, at your own pace.
• Kasturi La: The pass that makes this a circuit, with a southern view of Pandim and Kabru that the out-and-back route does not give.
• Forest descent: Moss-covered rhododendron and silver fir, then oak, chestnut and bamboo, a good stretch for pheasants including the Satyr Tragopan.
• Labdang homestay: The last night is in a Gurung village, with the trail ending near Tashiding.

The standard Goecha La trek is a 10-day out-and-back from Yuksom. The Kasturi La circuit is a 12-day loop that shares the first week and then goes a different way home. Here is how they differ, so you can choose.

Where the two routes match

Both start in Yuksom, climb through Sachen, Bakhim and Tshoka to Dzongri, cross Dzongri La from there, and follow the Prek Chu valley to Thansing for the Goecha La viewpoint and Samity Lake. On both you spend a rest day at Dzongri and have the same Kanchenjunga views.

Where they part

On the standard trek, the last two trekking days walk back down through Kokchurong, Phedang, Tshoka, Bakhim and Sachen to Yuksom. On the circuit, the day after the Goecha La viewpoint takes you from Thansing to Chamrey (6 - 8 hours, 17 km), well away from that path. A reserve day at Chamrey and Lampokhari Lake follows. Then comes Kasturi La, the camp at Kasturi, and a long forest descent to Labdang, with a drive back to Bagdogra.

What you gain and what it costs

• New ground on the way down: Lampokhari Lake, Kasturi La and the southern views of Pandim and Kabru are not on the out-and-back route.
• A quieter second half: the circuit leaves the main trail at Thansing, so the return is the part where you are least likely to share the path.
• Two more days: 12 days against 10, and a harder return, with a steep descent from Kasturi La and one of the longest days, Thansing to Chamrey.
• A built-in reserve day: the circuit has one flexible day at Chamrey for weather, which the shorter trek does not need.

If it is your first trek above 4,000 m, or you only have ten days, the standard Goecha La trek is the sensible choice. If you want the Goecha La trail and a loop, tell us your dates and experience and we will say which fits.

Everything on this circuit builds towards one long day from Thansing. It is the Goecha La viewpoint day, and it is the hardest 15 km of the trek.

Getting to Thansing

The day before, you leave Dzongri (3,960 m) for Thansing (3,890 m) through Kokchurong (3,660 m), 5 - 7 hours and about 11 km. You enter the Prek Chu valley over a small pass, with a gradual climb, a sharp drop and another gradual climb to the wide camp at Thansing. Pandim, Tenchenkhang, the Kabru group and Kanchenjunga stand around it. Thansing is where you sleep before and after the Goecha La day.

The viewpoint day

You start very early in the morning and climb past Lamuney (4,150 m) towards the Goecha La viewpoint for sunrise on the south-east side of Kanchenjunga. Then you slow down and spend the rest of the morning by Samity Lake. The plan is to be back at Thansing by noon. The day is 7 - 9 hours and about 15 km in all, and it is one of the longest of the trek.

Why it works as day 7

You arrive here after a full day at Dzongri and a gentler walk to Thansing, with nights at 3,960 m and 3,890 m behind you. That is the reason for the order of the days. We do not push to the viewpoint on arrival.

• Early start: the sunrise at the viewpoint is the reason for leaving in the dark, so it matters more than speed.
• Pace: you walk with your guide at your group's pace, and we turn back when that is the right call.
• Camp afterwards: you return to the same Thansing camp, so you can rest before the next day's long walk to Chamrey.

The day is the same on the standard Goecha La trek. What this circuit adds comes after it.

After Thansing, the trek leaves the Goecha La trail and becomes a different journey. It spends four days on ground few trekkers see.

Thansing to Chamrey

The day is 6 - 8 hours and about 17 km. You start in the soft meadows of Thansing, and the path soon becomes rockier. The trail weaves in and out of rhododendron and juniper forest and alpine scrub, with steep ups and downs. Chamrey sits at 4,150 m, a quiet, remote camp.

The reserve day at Lampokhari

The next day is a flexible reserve day. If the earlier high days lost time to weather, it takes up the slack. If not, we use it to walk to the lakes around Lampokhari (about 4,300 m, 5 hours and 10 km as a round trip) at an easy pace. The ground around the lake is mostly green and alpine, with some rocky stretches and boulders on the trail. We keep this day flexible because the weather decides it, not the schedule.

Kasturi La and the descent

The next day you cross Kasturi La and drop to the camp at Kasturi (3,650 m), 5 - 7 hours and about 14 km. The pass is the high point of the return route. From the ridge you see Pandim and Kabru from the south. On the way down the alpine scrub gives way to moss-covered rhododendron and silver fir, and this forest is known for pheasants, including the Satyr Tragopan. The descent from the pass is steep.

Kasturi to Labdang

The last walking day is a long, steady descent, 4 - 6 hours and about 12 km, through oak, chestnut and bamboo to Labdang at 1,900 m. On the way you have a last look at the Jupono glacier and walls before the tree line closes in. You spend the night in a homestay in a Gurung village, and the next morning we drive you to Bagdogra.

This is a strenuous trek. Most days are 5 - 8 hours, and a few reach 8 - 9, with steep climbs and descents. The trail goes up to 4,300 m. The itinerary is built so that your body has time to adjust before the long days.

How the altitude builds

• Days 1 - 2: Yuksom at 1,706 m, with a full day of gentle walking in the village before you start.
• Day 3: Yuksom to Tshoka (2,956 m), 7 hours and about 16 km, a long climb through forest.
• Day 4: Tshoka to Dzongri (3,960 m), 5 - 7 hours, over Phedang and Deurali Top.
• Day 5: a full day at Dzongri, for Dzongri Top (4,300 m) at sunrise and Dzongri La. You sleep at the same height, which is the point of the day.
• Days 6 - 7: Thansing (3,890 m), then the Goecha La viewpoint day, returning to Thansing.
• Days 8 - 9: Chamrey (4,150 m), the highest camp, with a reserve day.
• Days 10 - 11: Kasturi (3,650 m), then the long descent to Labdang (1,900 m).

The longest days are day 7 (7 - 9 hours, 15 km) and day 8 (6 - 8 hours, 17 km). They are back to back, so you meet them after the rest day at Dzongri, not before.

What we ask of you

You should be fit before you come. Regular cardio training in the weeks before matters more here than on a gentler trek, and previous multi-day trekking at altitude helps. The camps are remote, and evacuation may not be possible from all of them, so we plan the days conservatively and the reserve day is real.

What sleeping high means in practice

You sleep at about 4,000 m on several nights. We walk slowly, drink plenty and keep an eye on how everyone feels. If someone is not acclimatising, we say so, and we turn back when that is the right decision.

If you are not sure the trek is right for you, the Dzongri La trek is a shorter way to see Dzongri and the same forests.

This is how the 12 days work in practice, from the airport to the airport.

Arrival and departure

We pick you up at Bagdogra Airport (or New Jalpaiguri railway station) and drive you to Yuksom, a long day of about 7 hours via Jorethang and Legship, with a lunch stop at Jorethang. The road can be slow, so plan to land in the morning. After the trek, the drive from Labdang back to Bagdogra takes 6 - 7 hours, and we drop you at the airport or the station. The last day is a full driving day, so plan onward flights for the evening.

Permits

The trek is inside Khangchendzonga National Park, and we arrange the permits and forest entry. Foreign nationals also need a Sikkim Restricted Area Permit, which is applied for online and must be approved before the Melli check post; we handle this once we have your passport details. Indian nationals do not need a permit for Sikkim.

Season

The best months are March to May and September to December. Spring can bring snow cover on the high ground; autumn brings open ground, stable weather and clearer skies. Both work. Temperatures on the trek range from about -8 to 20 degrees Celsius, so we advise a good warm layer for the nights at Dzongri, Thansing and Chamrey.

The team and the camps

The nights are in hotels at Yuksom, camps at Tshoka, Dzongri, Thansing, Chamrey and Kasturi, and a homestay at Labdang. Your group is private and a local team cooks, carries and walks with you. We carry our waste out and leave the camps as we found them.

Next step

Tell us your dates, your trekking experience and your pace, and we will shape the days. If you would like to see the Goecha La viewpoint without the loop, our Goecha La trek is the shorter option.
