Mangan & Lachung, 3 Days

Things to carry

• Warm layers — the high lakes and the north Sikkim valleys sit above 3,500 m even in summer
• Valid photo ID — the Tsomgo, Nathang and north Sikkim roads are checked at army checkposts
• Shoes with grip for the monastery steps and the trek paths
• Sunblock and sunglasses — the high-altitude sun is strong even when it is cold

Important notes

A 3-day private itinerary. Longer versions add stops rather than padding existing days.,The east, north, west and south of Sikkim are four separate roads from the Teesta valley; routes that cross between them include the drive rather than implying they adjoin.,The Tsomgo, Nathang and north Sikkim roads cross army checkposts and need photo ID; permits are arranged for the high roads.,The high north Sikkim roads are only run in the warmer months — the valley of flowers and the high lake are closed by snow in the depths of winter.,Routes that cross into West Bengal include those places in the same itinerary; the drive down the Teesta is stated rather than implied.
