Chopta Valley, North Sikkim – A High-Altitude Wonderland Near Thangu

North Sikkim never runs out of surprises. Just when you think you’ve seen the best of the Himalayas, another valley appears around the bend with a completely different personality. Chopta Valley, perched at around 13,200–14,000 ft, is one of those rare places that feels untouched even today—raw, dramatic and endlessly photogenic. Located just 20 minutes from Thangu, this valley is often the first real taste of the high-altitude Tibetan plateau that lies beyond.

Chopta Valley stays cold throughout the year, usually below 10°C, and in winter it slips below freezing even during the day. The valley is blanketed in snow for several months, and its rivers turn into sheets of hard ice, giving travellers the surreal chance to walk over frozen waterways. But if you arrive during spring, you would never guess the harshness of winter—pink, red and yellow wildflowers paint the valley floor in unbelievable colours.

The Landscape – Where Alpine Forests Fade Into the Tibetan Plateau

Chopta Valley marks one of the last green stretches on the road to Gurudongmar. As you drive from Lachen to Thangu, the transformation of the landscape is almost dramatic. The first half of the journey winds through forests, small waterfalls and meadows. But within 30 km, you climb nearly 4,500 ft, and the dense greenery quickly gives way to dwarf rhododendrons, junipers and then sparse, stony terrain typical of the trans-Himalayan region.

Beyond Thangu, the valley opens up fully—broad grasslands, icy rivers, patches of snow even in early summer, and the great peaks of North Sikkim looming in every direction. The air becomes thinner, the silence deeper, and the scenery far more dramatic than anything seen at lower altitudes.

Chopta Valley in Winter – Frost, Silence and Frozen Rivers

From December to March, Chopta Valley transforms into a white desert. Snow covers almost everything, and the rivulets that flow freely in summer freeze into crystal-hard surfaces. Walking over these frozen streams is one of the most unique experiences travellers have in Sikkim, though it must be done carefully and only with your driver or guide’s supervision. The temperatures often dip well below 0°C, so winter visits need proper warm clothing and precautions.

Despite the cold, this is the season when the valley looks its most dramatic—quiet, still, and unbelievably beautiful.

Spring in Chopta Valley – Colours After Snow

By April and May, the snow melts and Chopta Valley bursts into life. Rhododendrons bloom beside the streams, the meadows turn green again, and the temperature becomes far more pleasant for sightseeing. This is also a great time for photographers and travellers seeking a softer, more colourful version of the high Himalayas.

Trek to Muguthang Valley – The Higher, Wilder Frontier

For the adventurous, Chopta Valley is only the beginning. A tough but rewarding trek leads to Muguthang Valley at around 15,500 ft, one of the least visited yet most stunning landscapes in North Sikkim. Muguthang is almost completely uninhabited except for a few nomadic settlements, and the scene here is pure high-altitude wilderness—stone cliffs, glacial streams, grazing yaks and huge open spaces that feel like Tibet. The trek is usually undertaken by prepared groups with proper acclimatisation.

How to Reach Chopta Valley – The Journey from Lachen

All travellers enter North Sikkim via Gangtok–Mangan–Chungthang, Lachen.
The standard routing is:

Stay overnight at Lachen → Early morning drive to Thangu → Visit Chopta Valley → Continue (Indians) to Gurudongmar Lake → Return to Lachen

Distances:

• Lachen to Thangu: ~30 km

• Thangu to Chopta Valley: 5–6 km (20 minutes)

The altitude gain is steep, so travellers are advised to:

• Stay hydrated

• Avoid heavy meals

• Avoid alcohol

• Move slowly and avoid exertion

The journey itself is stunning—rivers, cliffs, waterfalls and the first glimpses of the Tibetan plateau.

Where to Stay – Lachen and Thangu

Visitors usually stay in Lachen since this is where most hotels, lodges and homestays are located. Accommodation ranges from simple family-run homestays to comfortable mid-range hotels with heating arrangements.

Staying at Thangu is possible but requires special permits, and facilities are extremely basic. At this altitude, proper acclimatisation is essential, so most tourists prefer returning to Lachen after sightseeing.

NBTT Travel Solution Pvt. Ltd. can arrange suitable accommodation based on your comfort level and budget.
