HOW TO REACH SIKKIM

A Complete Guide by Air, Rail and Road (2026)

Overview: The easiest way to reach Sikkim is to fly into Bagdogra Airport (IXB) near Siliguri, then drive about 4 hours (roughly 124 km) to Gangtok along NH10. The nearest railway station is New Jalpaiguri (NJP), a similar distance away. Sikkim’s own Pakyong Airport sits closer to Gangtok, but its commercial flights have been on and off, so most travellers still route through Bagdogra.

TL;DR: How to Reach Sikkim in 40 Seconds

Sikkim has no fully reliable airport of its own yet, so nearly everyone reaches it through the plains of North Bengal. Fly to Bagdogra (IXB) or take a train to New Jalpaiguri (NJP), both near Siliguri, then travel by shared jeep, reserved taxi or SNT bus into the hills. The drive to Gangtok takes about 4 hours on NH10 beside the Teesta river. Indians need no permit to enter Sikkim; you only need permits for protected areas such as Nathu La, Tsomgo Lake and North Sikkim. Foreign nationals need a free entry permit, issued on arrival.

Getting to Sikkim is part of the trip, not just the dull bit before it. There is no way to fly straight into Gangtok and step off onto Mahatma Gandhi Marg, and once you understand why, the whole journey makes more sense. Sikkim is a small Himalayan state wedged between Nepal, Tibet and Bhutan, with steep terrain and unpredictable mountain weather. That geography is exactly what makes it beautiful, and it is also why you reach Sikkim through the North Bengal plains rather than by landing in the middle of it.

This blog lays out how to reach Sikkim by air, by rail and by road, with honest distances, drive times, rough fares and permit rules as of July 2026. Whether you are coming from Kolkata, Delhi or somewhere in between, you will find the fastest route, the cheapest route and the one most people actually take.

How to Reach Sikkim: Air vs Rail vs Road at a Glance

Air is fastest, rail is cheapest for long distances, and road is how you cover the final stretch no matter which you choose. Every route ends with a scenic 4-hour mountain drive into Sikkim.

Prices are indicative for July 2026 and move with season, fuel and demand. Treat them as planning figures, not quotes.

How to Reach Sikkim by Air

The nearest reliable airport to Sikkim is Bagdogra (IXB) in West Bengal, about 124 km and a 4-hour drive from Gangtok. Sikkim’s own Pakyong Airport is closer at around 30 km, but its commercial flights have run intermittently, so plan around Bagdogra.

Bagdogra Airport (IXB): the practical gateway

Bagdogra, near Siliguri, is the airport almost every Sikkim traveller uses. It has multiple daily flights from Delhi, Kolkata, Guwahati, Mumbai, Bengaluru and other major cities, with IndiGo, Air India, Akasa and others operating the routes. A flight from Kolkata takes just over an hour; from Delhi it is roughly two and a quarter hours. Once you land, you pick up a taxi or a shared jeep outside the terminal and drive to Gangtok, a journey of about 4 hours along NH10 following the Teesta river.

Pakyong Airport (PYG): closer, but check before you count on it

Pakyong is Sikkim’s only airport, built dramatically on a ridge about 30 km south of Gangtok. On paper it is the closest airport to the capital. In practice, its position at over 4,500 feet leaves it exposed to mist, low cloud and monsoon build-ups, and commercial service has started and stopped several times since 2019. 

As of July 2026, do not build your trip around a Pakyong flight. Check current schedules when you book, and keep Bagdogra as your fallback. It may become operational soon, although there hasn’t been any official confirmations as of yet. 

Helicopter to Gangtok

A helicopter service has at times connected Bagdogra with Gangtok in roughly 30 minutes, run in association with Sikkim Tourism. It carries only a handful of passengers, runs subject to weather, and can be suspended for long stretches, so treat it as a bonus rather than a plan. 

How to Reach Sikkim by Rail

The nearest major railway station to Sikkim is New Jalpaiguri (NJP) in Siliguri, about 120 to 125 km and a 4 to 4.5-hour drive from Gangtok. There is no railway station inside Sikkim yet, though a new line to Rangpo is being built.

New Jalpaiguri is one of the best connected stations in the region, with direct trains from Kolkata (the Darjeeling Mail and others, roughly 10 to 12 hours overnight), Delhi (around 22 to 26 hours), Guwahati and other cities. Train fares are gentle on the wallet, from a few hundred rupees in sleeper class to a couple of thousand in higher AC classes, which is why rail is the budget traveller’s favourite way to reach Sikkim.

Siliguri Junction is a smaller station a little closer to the hills, but it has fewer long-distance trains, so most travellers still book to NJP. From either station you step straight into the shared-jeep and taxi network for the drive up to Gangtok.

Worth knowing: the Sivok to Rangpo railway line, which will bring trains into Sikkim itself for the first time, is under construction. It is not open yet, so for now NJP remains your railhead. It is estimated to get completed by December 2027 (tentative date)

How to Reach Sikkim by Road

Sikkim connects to the rest of India mainly through NH10, the highway that runs from Siliguri along the Teesta river up to Gangtok. From Siliguri, NJP or Bagdogra you can take an SNT bus, a shared jeep or a reserved taxi, with the drive to Gangtok taking about 4 hours.

NH10, the road into Sikkim

NH10, (formerly called NH31A) , is the main road into Sikkim, running along the Teesta gorge and climbing past the border checkpost at Rangpo.During heavy monsoon the road can suffer landslides and short closures, so in July and August it is wise to start early and keep your plans flexible.

Buses, shared jeeps and taxis

Sikkim Nationalised Transport (SNT) runs budget buses from its Siliguri terminal to Gangtok for roughly ₹200 to ₹300, the cheapest option going. Shared jeeps, the workhorses of the hills, leave throughout the day and cost about ₹400 to ₹600 a seat from NJP or Siliguri. If you want the car to yourself, a reserved taxi from NJP or Bagdogra to Gangtok runs from about ₹3,000 for a small hatchback to ₹4,500 or ₹5,500 for an SUV, depending on season and vehicle.

One quirk to plan for: West Bengal-registered taxis usually drop passengers at Deorali taxi stand, about 2 km below central Gangtok, rather than in the middle of town. From there a short local Sikkim taxi to your hotel costs another ₹200 to ₹400. It catches first-timers off guard, so keep small cash handy.

Distance and Travel Time to Gangtok from Each Entry Point

From the main entry points, Gangtok is about 4 hours away by road: 124 km from Bagdogra Airport, 120 to 125 km from New Jalpaiguri, and 114 km from Siliguri.

Key Places and Terms You Will See on the Way

A quick glossary of the names that come up when you plan how to reach Sikkim, so nothing on your ticket or permit confuses you.

• Bagdogra Airport (IXB): The main airport for Sikkim, located near Siliguri in West Bengal, about 124 km from Gangtok, with daily flights from major Indian cities.
• Pakyong Airport (PYG): Sikkim’s own airport, roughly 30 km from Gangtok on a mountain ridge, where commercial flights have run intermittently because of weather.
• New Jalpaiguri (NJP): The nearest major railway station to Sikkim, in Siliguri, well connected to Kolkata, Delhi and Guwahati.
• Siliguri: The North Bengal transport hub that ties together Bagdogra airport, NJP station and the bus terminal, effectively the doorstep to Sikkim.
• NH10 (formerly NH31A): The national highway that runs from Siliguri along the Teesta river to Gangtok, the main road route into Sikkim.
• Inner Line Permit (ILP): An entry permit that, in Sikkim’s case, applies to foreign nationals entering the state. Indian citizens do not need it to enter Sikkim and only require permits for specific protected areas.
• Rangpo: The checkpost town on the West Bengal and Sikkim border on NH10, where you cross into Sikkim and where foreign nationals can get their entry permit.

Do You Need a Permit to Reach Sikkim?

Indian citizens do not need any permit to enter Sikkim or visit Gangtok, Pelling, Namchi or Ravangla. You only need permits for protected areas such as Nathu La, Tsomgo (Changu) Lake, Zuluk and North Sikkim. Foreign nationals need a free entry permit, available on arrival.

For Indian travellers

Most of Sikkim is open to Indian visitors with no paperwork at all. Permits come into play only for restricted, border-sensitive zones: Tsomgo Lake, Baba Mandir and Nathu La on the China border; the North Sikkim circuit of Lachung, Lachen, Yumthang Valley, Zero Point and Gurudongmar Lake; and the Silk Route around Zuluk. These are arranged through a registered Sikkim tour operator, usually the day before, using a couple of passport photos and a photocopy of a government photo ID such as a Voter ID, Passport or Driving Licence. Carry the originals too, and note that Aadhaar alone is often not accepted for these permits.

For foreign travellers

Foreign nationals need an entry permit to set foot in Sikkim, historically referred to as an Inner Line Permit and now issued as a Sikkim entry permit or Restricted Area Permit. It is free and can be obtained on arrival at the Rangpo checkpost, at Bagdogra Airport, or in advance at Sikkim House in Delhi or Kolkata, typically valid for 30 days. For protected areas such as North Sikkim, foreigners need an additional Protected Area Permit, must travel in a group of at least two, and must book through a registered operator. Nathu La is not open to foreign visitors.

Permit rules and fees change, so confirm the current position before you travel. This is one area where a local operator earns its keep. 

Best Way to Reach Sikkim from Delhi, Kolkata and Other Cities

From Delhi, fly to Bagdogra (about 2 hours 15 minutes) then drive to Gangtok. From Kolkata, either fly to Bagdogra in just over an hour or take an overnight train to New Jalpaiguri. From the Northeast, reach Siliguri or NJP by road or rail and continue by shared jeep.

From Delhi, flying is the sensible choice given the distance. Book a morning flight to Bagdogra so you have daylight for the mountain drive, since arriving at Gangtok after dark means missing the scenery and, in monsoon, driving a landslide-prone road at the worst time. From Kolkata you have a real choice: fly for speed, or take an overnight train to NJP and save money while sleeping through the journey. From Guwahati and the rest of the Northeast, most people reach Siliguri or NJP by road or rail and then join the shared-jeep network up the hill.

Insider Notes: Reaching Sikkim Smoothly

A few practical things that generic guides skip, drawn from how the route actually behaves through the year.

• Time your drive for daylight. Aim to leave Bagdogra or NJP by early afternoon at the latest. The NH10 stretch along the Teesta is at its most beautiful, and safest, in daylight, and hill drivers prefer not to run it late.
• Monsoon needs a buffer day. In July and August, landslides can close NH10 for a few hours or occasionally longer. If you are flying home on a tight connection, keep a spare day between Gangtok and your onward flight.
• Shared jeeps are cheapest but leave when full. If you are on a budget and flexible, a shared jeep from Siliguri or NJP is a fraction of a reserved taxi. If you are on a schedule or travelling with family, reserve the whole vehicle.
• Carry ID originals and photos. Even though Indians need no permit to enter Sikkim, you will need an ID for hotel check-in and for any protected-area permit you arrange later. Keep two passport photos and a photo ID copy in your bag.
• The Deorali drop is normal, not a scam. West Bengal taxis stopping at Deorali rather than central Gangtok is a real rule, not a driver trying to shortchange you. Budget a small local taxi fare to finish the last couple of kilometres.

Planning Your Sikkim Trip with eSikkim Tourism

Reaching Sikkim is straightforward once someone has mapped the flights, trains, permits and mountain drives into a single plan, and that is the part worth getting right. In our view, the smoothest way to arrive is to lock your Bagdogra or NJP arrival to a daytime onward drive, arrange any protected-area permits in advance, and keep a little slack in the schedule for mountain weather.

At eSikkim Tourism, our travel experts can build a customized Sikkim itinerary around exactly this kind of thinking: your arrival city, your travel dates, the permits you will need, and the right balance of comfort and cost for getting up the hill.
