Ultimate Guide to North Sikkim: Lachung, Lachen, Gurudongmar Lake, and More
Nestled in the lap of the Eastern Himalayas, North Sikkim is a world where nature still reigns supreme. Known for its high-altitude lakes, snow-capped peaks, gurgling waterfalls, and serene villages, this region offers one of the most breathtaking experiences in all of India. If you are a traveler looking for untouched beauty and raw Himalayan adventure, North Sikkim should be at the top of your bucket list.
At Sikkim Diaries Tours & Treks, we take you beyond the ordinary to explore the most beautiful corners of this Himalayan paradise — from the peaceful villages of Lachung and Lachen to the awe-inspiring Gurudongmar Lake and beyond.
An Overview of North Sikkim
Located about 120 km from Gangtok, North Sikkim is a restricted zone that requires an Inner Line Permit to visit. The area remains open to Indian tourists throughout the year (weather permitting), while foreign nationals can access select areas with special permits.
This region is home to some of Sikkim’s most iconic destinations such as:
- Lachen – The gateway to Gurudongmar Lake
- Lachung – The base for Yumthang Valley and Zero Point
- Chopta Valley – Known for its pristine alpine beauty
- Yumthang Valley – The “Valley of Flowers” of Sikkim
- Gurudongmar Lake – One of the world’s highest lakes
Each of these destinations offers something unique — be it adventure, spirituality, or breathtaking natural scenery.
Lachung – The Gateway to Yumthang Valley
A picturesque mountain village situated at an altitude of around 8,600 feet, Lachung is blessed with apple orchards, wooden houses, and cascading streams. It is the ideal stopover before exploring the Yumthang Valley and Zero Point (Yumesamdong).
Top Attractions in Lachung:
- Yumthang Valley – Famous for its rhododendron sanctuary that blooms from March to May.
- Zero Point – The last accessible point before the Indo-China border, covered in snow most of the year.
- Lachung Monastery – A peaceful 19th-century monastery with traditional Tibetan architecture.
- Best Time to Visit: March to June for flowers, November to February for snow.
Lachen – The Tranquil Himalayan Hamlet
About 47 km north of Lachung lies Lachen, a charming village perched at 8,800 feet, surrounded by dense forests and alpine meadows. This serene destination is the base for visiting Gurudongmar Lake and Chopta Valley.
Top Attractions in Lachen:
- Gurudongmar Lake – Situated at 17,800 ft, it is one of the highest lakes in the world and holds sacred significance for both Buddhists and Sikhs.
- Chopta Valley – Known for its untouched beauty and ideal for nature photography.
- Lachen Monastery – A spiritual retreat offering a panoramic view of the valley.
Best Time to Visit: April to June and October to December.
- Gurudongmar Lake – The Jewel of North Sikkim
A trip to North Sikkim remains incomplete without witnessing the pristine blue waters of Gurudongmar Lake. Located near the Tibetan border at an altitude of 17,800 ft, this sacred lake is named after Guru Padmasambhava (Guru Rinpoche).
Despite the freezing temperatures, a part of the lake never freezes — a phenomenon believed to be miraculous by locals. The thin air, biting cold, and panoramic Himalayan backdrop make this destination a once-in-a-lifetime experience.
Travel Tip: Start early from Lachen (around 4:00 AM) to reach Gurudongmar Lake by morning, as oxygen levels decrease at higher altitudes post-noon.
- Yumthang Valley & Zero Point – Nature’s Wonderland
Often called the “Valley of Flowers”, Yumthang Valley sits at around 11,800 ft and is covered in colorful rhododendrons and alpine flowers during spring. The valley transforms into a snowy wonderland during winter, making it one of the most photogenic spots in Sikkim.
A further drive of 25 km leads to Zero Point (Yumesamdong), where you’ll find snow-covered landscapes even in April.
Note: Zero Point is located near the Indo-China border and requires additional permits, which Sikkim Diaries Tours & Treks can easily arrange.
