Sikkim travel questions, answered by a local desk

March to May for rhododendron blooms and mild weather (10°C–22°C), and October to November for the clearest views of Mt Kanchenjunga. December to February is for snow.

December to March, sometimes into April and May at high altitude: Tsomgo Lake, Nathula, Baba Mandir, Zuluk, Lachen, Lachung, Yumthang, Zero Point and Gurudongmar Lake.

Gangtok, Pelling and South Sikkim are fine and 30–50% cheaper. North Sikkim and Nathula suffer landslides and road closures, so avoid them in monsoon.

Gangtok stays between 4°C and 22°C through the year, while Zero Point and Gurudongmar drop to -15°C to -20°C in winter.

Not for Gangtok, Pelling, Namchi, Ravangla or Yuksom. A Protected Area Permit (PAP) is mandatory for Tsomgo Lake, Nathula, Baba Mandir, Zuluk, Lachen, Lachung, Yumthang, Zero Point and Gurudongmar Lake.

No. Aadhaar and PAN cards are not accepted for permits. Carry an original Voter ID, Driving Licence or Passport, plus a birth certificate for children and passport-size photos.

No. Foreign nationals and OCI holders need an RAP/ILP to enter Sikkim and are not allowed at Nathula, Gurudongmar or Zuluk. Tsomgo, Lachung and Yumthang are allowed for groups of 2+ via a registered agency.

Mondays and Tuesdays, plus heavy-snow days. Plan it for Wednesday to Sunday and cross 3rd Mile checkpost before 10 AM.

Two per person per permit route: for example Tsomgo/Nathula plus North Sikkim means four photos and four ID photocopies each.

Bagdogra (IXB) is 124 km and 4.5–5.5 hours away but has reliable all-weather flights. Pakyong (PYG) is only 30 km from Gangtok but has had no scheduled flights since June 2024, so plan on Bagdogra.

NJP is about 120 km and 4.5–5 hours from Gangtok via NH10 by shared jeep (₹500–₹800 a seat) or a reserved taxi (₹3,500–₹7,500 depending on car and season).

No. Only Sikkim-registered commercial tourist vehicles with valid permits are allowed on the restricted border circuits. Park in Gangtok and hire a permit-ready SUV.

3–4 days for Gangtok with Tsomgo/Nathula; 5–7 days to add North Sikkim or Pelling; 8–10 days for East, North, South and West together.

North Sikkim is for snow, high lakes and alpine valleys. Pelling is lower, gentler and has the closest Kanchenjunga views, a skywalk, waterfalls and monasteries, so it suits families and seniors.

No. You must sleep in Lachen (9,000 ft) and leave at 4–5 AM to reach the lake at 17,800 ft before the midday winds.

A 2–3 night East Sikkim circuit: Aritar Lake, Zuluk's 32 hairpin bends, Thambi Viewpoint, Nathang Valley, Kupup Elephant Lake and Baba Mandir, ending at Tsomgo and Gangtok.

MG Marg, Enchey Monastery, Rumtek Monastery, Ganesh Tok, Hanuman Tok, Tashi Viewpoint, Do Drul Chorten, the Namgyal Institute of Tibetology, Banjhakri Falls and the ropeway.

The Glass Skywalk and Chenrezig statue, Pemayangtse Monastery, Rabdentse ruins, Khecheopalri Lake, Kanchenjunga Falls and the Singshore Bridge.

Yumesamdong, the end of the civilian road at 15,300 ft beyond Yumthang Valley, famous for snow and views near the Tibet border. It costs an extra ₹3,500–₹4,000 per vehicle in cash.

Roughly ₹18,000–₹25,000 per person for a 6–7 day mid-range trip in a group of four, and ₹7,500–₹11,500 for a 3–4 day Gangtok trip. Transport is 40–50% of the cost because cabs are priced per vehicle.

Budget hotels and hostels start at ₹748–₹1,429 a night, 3–4 star hotels average ₹1,800–₹3,700, and luxury resorts run ₹7,200–₹11,199.

Only community homestays, typically ₹1,500–₹1,800 per person with all meals. Book luxury stays in Gangtok before or after the Silk Route.

Spend a night in Gangtok first, drink 3+ litres of water, avoid alcohol and smoking the day before, carry a portable oxygen can, and never take infants or anyone with heart or lung conditions above 15,000 ft.

Jio and Airtel are fine in Gangtok, Pelling and Namchi. In Lachen and Lachung only BSNL works reliably; the high passes have no signal at all.

No reliable ATMs. Withdraw ₹6,000–₹10,000 in small notes in Gangtok, Mangan or Namchi because UPI and cards fail in North Sikkim and on the Silk Route.

Yes. Single-use plastic bottles are banned and fines reach ₹5,000 in Lachen and Lachung. Carry a reusable flask; hotels provide boiled or filtered water.
