How to plan North Sikkim: Lachung, Yumthang and Gurudongmar

North Sikkim is the part of the state people remember, and it is also the part that punishes a badly made plan. The roads are long, the altitude is real, and the permit cannot be arranged on the morning you want to travel. This is how we run it, and what we tell guests before they book.

The permit is the first thing, not the last

North Sikkim sits inside a protected area. Beyond Chungthang — that is Lachen, Lachung, Yumthang, Zero Point and Gurudongmar — you cannot travel on your own. The permit is issued to a registered Sikkim operator, against a named vehicle and a named driver, for specific dates. It is not something you collect at a counter on the way up.

What that means in practice is simple. Send us your ID copies and photographs before you leave home, not when you land. We file the paperwork in Gangtok while you are still on the road from Bagdogra, and the permit is in the driver's folder before you sleep the first night.

• Indian nationals — a voter ID, passport or Aadhaar copy plus two passport photographs each.
• Foreign nationals — different rules apply, and Gurudongmar in particular is not open to foreign passport holders. Tell us the nationality of every guest at enquiry stage so we do not sell you a day you cannot take.
• Children — carry a birth certificate or school ID; the checkpost does ask.

Why two nights is the minimum

People ask us for North Sikkim as a day trip out of Gangtok every season, and every season the answer is the same. It cannot be done. Gangtok to Lachung is a full driving day on a road that is repaired continuously and closes without notice. Doing Yumthang the next morning and driving all the way back the same day means fourteen hours in a car at altitude, which is how holidays turn into headaches.

The shape that works is the one in our Gangtok and North Sikkim package: two nights in Gangtok to settle in, one night at Lachung for the Yumthang morning, then back down. If Gurudongmar is on your list, add a night at Lachen. Anything shorter, we will tell you honestly that we would rather not run it.

Altitude, and how to be sensible about it

Lachung and Lachen sit near 2,700 metres. Yumthang is higher again, Zero Point higher still, and Gurudongmar is above 5,000 metres. Most guests feel nothing worse than a mild headache and shortness of breath on the stairs. A few feel considerably worse, and that is not a fitness question — it affects fit young travellers as often as anyone else.

• Spend the first two nights in Gangtok rather than racing straight up. That acclimatisation is the whole point of the itinerary.
• Drink far more water than feels necessary, and skip alcohol on the night before a high day.
• Gurudongmar and Zero Point are morning trips. Get up, go, come down. Do not linger at the top for photographs.
• If you have a heart or lung condition, or you are pregnant, talk to your doctor before booking. Our drivers carry an oxygen can, but a can is a stopgap, not treatment.

The roads, honestly

The road to Lachung and Lachen is a working mountain road, not a highway. Expect stretches of loose surface, single-lane sections at repair points and river crossings where the tarmac simply is not there. This is why we send a Scorpio or a Bolero north rather than a sedan — ground clearance matters more than comfort on this route.

In monsoon, roughly mid-June to mid-September, landslides close sections of this road regularly. We do run North Sikkim in those months, but we build slack into the plan and we tell you upfront that a day may need to move. If your calendar has no give in it at all, pick a different season rather than a different operator.

When to go

• March to May — the reason most people come. Rhododendrons through the Yumthang valley, clear mornings, and snow still on the ground at Zero Point early in the window.
• October and November — the clearest skies of the year and the best mountain views. Cold, but dry.
• December to February — hard cold, and Gurudongmar and Zero Point are often shut by snow. Beautiful if you know what you are choosing.
• June to September — monsoon. Green, empty, cheaper, and genuinely unpredictable on the road.

What to carry

Layers rather than one heavy coat, because you will move through a fifteen-degree swing in a single morning. Gloves and a cap for the high days even in May. Cash, because card machines and mobile signal are both unreliable past Chungthang. Any regular medication in your hand luggage rather than the boot. And your ID originals — the permit copy in the driver's folder is not a substitute at a checkpost.

What we handle and what you handle

We file the permits, we send the vehicle and a driver who has run the route before, and we book the Lachung or Lachen night. You bring the documents on time and a plan with a day of slack in it. That division has worked for fourteen years.

If you want the trip costed properly, send us the dates and the number of guests. You will get a fixed, all-inclusive number back — fuel, tolls, permits, driver allowance and the night halt, with nothing added at a checkpost.
