When to go, how to get there, and what to pack.
Practical, season-by-season advice for Darjeeling, Gangtok, Nathula Pass and the rest of Sikkim, written by people who plan these routes every week.
Four seasons, four different trips.
There is no single best month. It depends on whether you want mountain views, snow, flowers or quiet roads.
Spring
Rhododendrons in Yumthang Valley and on the West Sikkim ridges, first-flush tea in Darjeeling, mild days and the best chance of reaching the high passes. Views can haze over by midday. Book early for May school holidays.
Monsoon
Lush valleys, full waterfalls and fewer visitors, but heavy rain brings landslides on the highways and frequent closures in North Sikkim and on the passes. Mountain views are rare. Plan generous buffers, or visit Darjeeling and Gangtok only.
Autumn
Rain-washed skies and the clearest views of Kanchenjunga, from Tiger Hill and Pelling. Many travellers consider this the best overall season. Durga Puja and Diwali weeks are very busy, so book well ahead.
Winter
Cold, crisp and often clear. Snow at Tsomgo, Nathula and Zero Point for those who want it, though heavy snowfall can close them for days. Darjeeling and Gangtok nights drop close to freezing. Pack properly.
Best time by destination
| Destination | Best months | Why |
|---|---|---|
| Darjeeling | Oct–Dec, Mar–May | Clear Kanchenjunga views in autumn; first-flush tea in spring. Toy-train services can be disrupted in heavy monsoon. |
| Gangtok | Oct–Dec, Mar–May | Comfortable most of the year. The best base for East and North Sikkim day trips. |
| Tsomgo Lake & Nathula | Apr–Jun, Oct–Nov | Frozen lake and snow in winter, but closures are more frequent. Nathula is generally open Wednesday to Sunday only. |
| North Sikkim (Lachung, Yumthang) | Apr–May, Oct–Nov | Rhododendron bloom in April–May. Access depends on road repairs after landslides; we confirm status before booking. |
| Pelling & West Sikkim | Oct–Dec, Mar–Apr | Some of the closest Kanchenjunga views, with monasteries at Pemayangtse and Sangachoeling. |

Ten things we tell every guest.
For altitude, safety and etiquette in detail, read our safety & responsible travel page.
Do not over-pack the itinerary
Hill roads are slow. Two hours on the map can take four. Aim for one major move per day.
Acclimatise before the passes
Spend a night in Gangtok before Tsomgo or Nathula, and in Lachung before Zero Point.
Bring the right ID
Original government photo ID with address, photocopies and passport photos for every traveller. See the permits guide.
Dress in layers, in every season
Mornings at Tiger Hill and the passes are cold even in May. Add a warm jacket, thermal layer, cap and gloves from October to March.
Waterproofs from June to September
A light rain jacket, quick-dry clothes and shoes with good grip for wet paths.
Sunglasses and sunscreen at altitude
Sun reflected off snow at 4,000 m burns quickly, even on cloudy days.
Carry a refillable bottle
Sikkim restricts small packaged-water bottles and single-use plastics.
Keep some cash
Card machines and ATMs are scarce beyond the main towns, and mobile signal can disappear for hours in North Sikkim.
Start early on sightseeing days
Mountain views are usually clearest in the morning, and clouds often build by midday.
Expect changes, and keep a plan B
A closed pass is normal here. We always have an alternative ready, so a closure does not mean a lost day.
