Lachen & Lachung

Twin highland villages of North Sikkim — gateway to Gurudongmar Lake and Yumthang Valley

Two villages, two high valleys

Lachen and Lachung are small settlements in North Sikkim, reached from Gangtok after a long mountain drive. Both require inner-line permits. Lachen (about 2,750 m) is the overnight base for Gurudongmar Lake, one of the highest lakes in India, visited at dawn. Lachung (about 2,700 m) is the base for Yumthang Valley — often called the Valley of Flowers — and, when the road is open, Zero Point closer to the Tibetan plateau.

Nights here are simple: guesthouses, early starts and cold air. Gurudongmar sits above 5,000 metres, so the morning can feel thin. Yumthang is lower and greener, with rhododendron and primula in late spring. The north is usually visited between May and June or October and November, when roads and weather are more reliable.

Lachen & Lachung

Famous for

  • Gurudongmar Lake, reached at sunrise from Lachen
  • Yumthang Valley’s open meadows and spring flowers
  • Zero Point (Yumesamdong) beyond Yumthang, when accessible
  • Highland village life and prayer-flag landscapes
  • Snow-covered roads and peaks in the colder months

Best time to visit

  • May to June: Yumthang in flower and the most popular window
  • October to November: clearer mountain views and colder nights
  • December to March: heavy snow; many high roads close
  • July to September: monsoon landslides make the north unreliable
