Are you planning to visit Sikkim but not sure how to reach the state? Sikkim is a paradise for travelers looking for serene mountainscapes, calming monasteries, and cultural experiences unique to the state. But if you’re planning a trip to Sikkim, it is essential that you know how to reach Sikkim, including major forms of transport and internal transfers. In this blog, we shall guide you on how to reach Sikkim, including flights, trains, and information on internal travel. Let’s get started!
How To Reach Sikkim By Air
The easiest way to reach Sikkim from most destinations in India is through flight. And the nearest major airport to fly to is the Bagdogra Airport (IXB) in West Bengal. Located near Siliguri, Bagdogra is the closest commercial airport to Sikkim, with connections to major Indian cities like Delhi, Kolkata, Mumbai, Guwahati, and Bengaluru.
Once you land at Bagdogra, you can hire a private cab, shared cab, or arrange a pre-booked transfer to Gangtok. The road journey can take anywhere between 4 to 5 hours, covering about 125 km. This travel time can also depend on traffic, weather, and road conditions.

How To Reach Sikkim By Train
Sikkim does not have a major railway station within the state either, so your best bet would be to use New Jalpaiguri Railway Station in West Bengal. The railway station is one of the most important railway junctions in eastern India and has regular connectivity to Kolkata, Delhi, Guwahati, and other major destinations.
From the railway station, direct cabs can be arranged to reach Gangtok in Sikkim, with the 120-km journey taking approximately 4 to 5 hours. Shared taxis are also popular among budget travelers.
How To Reach Sikkim By Road
Road travel is an integral part of any Sikkim trip. Whether you fly or take a train to West Bengal, you’ll eventually spend several hours on the road before reaching the state. The most common route is:
Bagdogra/Siliguri → Sevoke → Teesta → Rangpo → Gangtok
Rangpo is one of the main entry points into Sikkim.
For a road journey, you can choose between a private taxi, shared cab, or self-drive trip. Private taxis can be the most convenient option if you’re with a family or group, while shared taxis are suitable for solo and budget travelers.

Can You Drive Your Own Car To Sikkim?
Yes, you can travel to Sikkim by your own car, but only partially.
These are the places where self-drive is permitted:
- The main NH-10 corridor from Bagdogra / New Jalpaiguri to Gangtok
- Gangtok city area
- Tsomgo Lake + Baba Mandir + Nathula Pass (with additional paperwork)
- Gangtok to Pelling via Ravangla
- Pelling and West Sikkim, including Khecheopalri, Yuksom, Tashiding, and Hilley-Versey
- Pelling to Darjeeling via Singla
- Gangtok – Ravangla – Namchi – Pelling loop
- Gangtok to Mangan
These are the places where self-drive is not permitted:
- Old Silk Route (Rongli, Aritar, Zuluk, Nathang, Kupup): Inner Line Permit is strictly required and only Sikkim-registered vehicles are allowed
- Dzongu Lepcha Reserve: Requires Dzongu Special Permit
- Mangan → Chungthang and beyond (Lachung, Lachen, Yumthang, Zero Point, Gurudongmar, Cholamu, Thangu): Access closed to private vehicles from outside Sikkim
Knowing which areas allow private vehicles and which don’t can help you plan your Sikkim itinerary accordingly and avoid last-minute plan changes.
The drive from cities such as Kolkata can be done over multiple days, while travelers from nearby parts of North Bengal may reach Sikkim relatively quickly.
However, to drive on Sikkim’s road, one must have adequate experience of mountainous terrain, steep curves, and winding roads. One must be good at navigating through such terrain and also being quick in responding to sudden weather changes and occasional road closures.

How To Reach Sikkim From Kolkata?
Kolkata is often one of the most convenient points for travelers starting their journey from eastern India. You can either fly from Kolkata to Bagdogra and continue by road or take a train to New Jalpaiguri. Flying is the better choice if you want to save time whereas train travel can be more economical.
There are also long-distance bus services and private road-trip options, although travel time can vary significantly.
How To Reach Sikkim From Delhi & Mumbai?
Travelers from Delhi, Mumbai, and other parts of India will generally find it easiest to fly to Bagdogra.
From both Mumbai and Delhi, direct flights are available to Bagdogra, and from there one can arrange for a transfer to Gangtok. However, it is advised to keep track of flight ticket prices and book at least a couple of months in advance to secure good deals.
Getting Around Sikkim After You Arrive
Once you reach Gangtok, the most obvious question you’d have is how to get around Gangtok, and Sikkim by large.
For destinations like Nathula Pass, Tsomgo Lake, Lachung, Yumthang Valley, Pelling, and Ravangla, you might have to book a local taxi. Some areas require special permits, so you might have to arrange for the same. You can book local taxis and sort out permits from local, authorized travel agencies. Most travel agencies help you plan the entire Sikkim sightseeing journey and also customize the itinerary according to your needs. If you’re traveling independently, check permit requirements and road conditions before heading towards remote areas.
What Is The Best Way To Reach Sikkim?
Looking for speed and convenience? Fly to Bagdogra and make a transfer to Gangtok.
Wanting to travel on a budget? Take the train to New Jalpaiguri and continue your journey by a shared taxi to Gangtok. And if road trips excite you, drive from Siliguri or plan a longer road trip from Kolkata or another nearby city.
Ultimately, the best route depends on your starting city, budget and how much time you have. Regardless of how you arrive, the final mountain drive into Sikkim is what makes the entire journey worth it!
