What Actually Changes a Sikkim Trip
Permits, road distances and altitude shape every Sikkim itinerary more than hotel choice does. Protected-area permits for Tsomgo Lake, Baba Mandir, Nathula and North Sikkim are not optional, and Gangtok sits roughly 4.5 to 6 hours by road from Bagdogra, so travel days must be planned around transfers.

Before You Go to Sikkim
Book permits before you reach Gangtok, confirm your Bagdogra transfer in writing, and carry printed copies of every document.

From our travel specialists
What our team sees when planning these trips, beyond what the guidebooks say.
Confirmed 11 Oct 2026
- Practical
Local transport and road delays catch travellers out most often: journeys such as Gangtok–Pelling and Gangtok–Lachung can take much longer than map estimates because of mountain roads and checkpoints. Shared vehicles, permits and operator-arranged transfers also make independent point-to-point travel less straightforward than expected.[6][8]
Travellers commonly wish they had understood how long mountain-road journeys take, especially Gangtok–Lachung and Gangtok–Pelling, and that weather can change plans. They also advise checking permits for Nathu La and North Sikkim in advance and carrying ID copies and passport photos for every traveller, including children.[6][8]

Straight answers to help you plan — then personalise the trip with a specialist.
8 answered belowAsk a specialist anything about this trip — there’s no obligation.
Ask a specialistWhat is the best time to visit Sikkim?
October to mid-December and March to May are generally best for clear views, comfortable temperatures and sightseeing. October and November are especially reliable for clear skies, while April and May are strong choices for flowers and spring landscapes. Monsoon runs roughly June to September with higher landslide risk.
How many days are enough for a Sikkim trip?
Five to seven days covers Gangtok plus one western or northern circuit. Ten days allows a slower multi-region itinerary including Pelling, Yuksom, Lachung and Yumthang. Add a buffer day if your plan includes Nathula or North Sikkim, because road and weather conditions can change.
What is the average cost of a Sikkim tour package?
Indicative land-only twin-sharing packages range from about INR 18,000 per person for budget trips to INR 50,000 or more for premium programs. A typical 5- to 7-night land package costs approximately INR 18,000-50,000 per person on twin sharing, excluding flights. These are planning ranges, not confirmed Tripstor offers.
Is a permit required to visit Sikkim?
Indian citizens need no visa, but permits are required for protected and border areas such as Tsomgo Lake, Baba Mandir, Nathula, North Sikkim and selected Silk Route areas. Domestic-tourist permits are generally arranged through registered operators or issued through designated police and tourism offices. Carry photocopies and passport-size photographs.
How do I reach Sikkim by flight?
Fly to Pakyong when suitable services operate; Bagdogra is the main practical gateway, followed by a road transfer to Gangtok that generally takes 4.5 to 6 hours. Direct Delhi-Bagdogra services are commonly available. Kolkata-Bagdogra is about 1.25 hours by air. Mumbai, Chennai, Bengaluru, Hyderabad, Pune and Ahmedabad usually connect through Delhi or Kolkata.
Which places are best to visit in Sikkim?
Gangtok, Tsomgo Lake, Nathula, Pelling, Yuksom, Lachung-Yumthang and Ravangla are the main package destinations. Gangtok is the usual base for East Sikkim excursions. Pelling, Yuksom and Ravangla anchor the west and south. Lachung and Yumthang sit in North Sikkim and need a separate permit and an overnight stay.
Is Sikkim safe for family travel?
Yes for standard circuits with sensible acclimatisation and road planning, though high-altitude routes and monsoon travel require flexibility. Sikkim is generally safe for Indian tourists on standard circuits. Check current conditions before you travel, carry permit documents at checkpoints, and keep buffer days for weather delays.
Is Sikkim better than Darjeeling?
Sikkim is better for high-altitude scenery, monasteries and protected-area excursions; Darjeeling is easier for shorter, simpler hill holidays. Sikkim requires permits for border areas and involves longer road transfers. Choose Sikkim if you want Nathula, Tsomgo Lake and North Sikkim; choose Darjeeling for a quicker hill break.
