Gangtok to Lachung
Leave Gangtok at 10–11 am once permits are ready. The road runs north past Kabi Lungchok, Phodong and Mangan, with lunch around Mangan or Singhik. At Chungthang, where the Lachen and Lachung rivers meet to form the Teesta, you turn right up the Lachung valley. Arrive in Lachung in the evening at about 2,700 m. Dinner at your homestay, an early night, and a reminder to your driver that you are staying three nights, so the Yumthang trip can be tomorrow or the day after depending on weather.
Spend today: ₹200 lunch + ₹50 tea
