How to Reach Sikkim in 2025: Best Travel Routes & Tips

Sikkim, one of India’s most scenic and peaceful states, is nestled in the eastern Himalayas and draws travelers with its snow-capped mountains, vibrant culture, and calm monasteries. Whether you're a nature lover, a spiritual seeker, or simply looking for a cool escape from city life, Sikkim has something for everyone. But if you’ve never been before, your first question will probably be: how to reach Sikkim?

Reaching this beautiful state may seem tricky due to its hilly terrain and lack of a direct airport or major train station in its capital, Gangtok. However, with some basic planning, getting there is quite easy and absolutely worth the journey. This guide will give you all the information you need about the best ways to reach Sikkim by air, rail, and road—no matter where you're starting your journey from.

By Air: The Easiest and Fastest Option

The most convenient way to reach Sikkim is by flying into Bagdogra Airport, located in West Bengal. It is the nearest major airport to Gangtok, about 125 kilometers away. Bagdogra is well-connected with direct flights from major Indian cities such as Delhi, Kolkata, Mumbai, Bangalore, and Guwahati. From the airport, you can easily hire a private taxi or take a shared jeep to Gangtok. The scenic drive takes around 4 to 5 hours and offers beautiful views of rivers, forests, and hill towns.

For those who prefer an even closer arrival, Pakyong Airport in Sikkim became operational a few years ago. It is just 35 kilometers from Gangtok. While fewer flights land here compared to Bagdogra, it is still a great option if you’re lucky enough to find availability that fits your schedule. Flying into Pakyong reduces the drive time significantly and brings you directly into the heart of Sikkim.

By Train: A Scenic and Affordable Journey

If you’re traveling on a budget or enjoy train journeys, another option to explore when wondering how to reach Sikkim is the rail route. The nearest railway station is New Jalpaiguri (NJP), located near Siliguri in West Bengal. NJP is a major railhead and is well-connected to cities like Delhi, Kolkata, Chennai, and Guwahati. From NJP, you can continue your journey to Gangtok by taxi or shared jeep. The drive from NJP to Gangtok takes roughly 4 to 5 hours, similar to the journey from Bagdogra.

Train travel to NJP is especially popular among backpackers, families, and students, as it’s cost-effective and allows you to enjoy the changing landscapes from the plains to the hills. Booking your train tickets early through the IRCTC website is highly recommended, especially during holiday seasons or long weekends.

By Road: An Adventurous Option Full of Views

For travelers who enjoy road trips, driving to Sikkim or taking a long-distance bus can be an adventurous and rewarding experience. Gangtok is well-connected by road to Siliguri, Darjeeling, and Kalimpong. National Highway 10 is the main route, and it offers picturesque views of mountain rivers, forests, and small villages along the way.

You can take a private taxi or board a shared jeep from Siliguri or NJP. There are also regular bus services run by the Sikkim Nationalized Transport (SNT) from Siliguri to Gangtok. The roads are generally in good condition, though travel can be slow due to winding mountain paths. During the monsoon months (July to September), landslides can cause delays, so always check the weather forecast and road status before setting off.

If you're self-driving, make sure your vehicle is well-maintained and you're comfortable navigating hill roads. Also, carry all essential documents, including ID proof, and be prepared for possible police checks en route.

How to Reach Sikkim from Major Indian Cities

Understanding how to reach Sikkim also depends on your starting point. From Kolkata, one of the closest metro cities, you can either fly to Bagdogra (about 1 hour) or take an overnight train to NJP. From Delhi or Mumbai, flying to Bagdogra is the quickest and most convenient option, while trains take considerably longer. Once you arrive at either Bagdogra or NJP, continue by road to Gangtok.

From Guwahati in Assam, you can take a direct train to NJP or a flight to Bagdogra. If you're traveling from Bhutan, Nepal, or Bangladesh, special cross-border routes are also available, but these may require advance planning and additional permits.

Permits and Travel Requirements

Indian citizens do not need a permit to enter Gangtok or most other areas in Sikkim. However, if you plan to visit restricted or border areas such as Tsomgo Lake, Nathula Pass, Zuluk, Lachung, or Lachen, you will need to obtain an Inner Line Permit (ILP). These can usually be arranged through your hotel or travel agency in Gangtok. Foreign nationals are allowed to enter Gangtok with valid Indian visas but need additional permits for restricted areas, and they must travel in groups through registered tour operators.

It’s also a good idea to carry multiple copies of your ID, passport-sized photos, and your travel bookings, especially if you’re planning to explore the more remote parts of the state.

Final Thoughts: Getting There is Part of the Adventure

Sikkim may not have a major international airport or railway station in its capital, but that’s exactly what makes the journey feel like an adventure. Once you decide how to reach Sikkim—by air, train, or road—you’ll realize that the experience of getting there is just as memorable as the destination itself. Every route is filled with natural beauty, charming pitstops, and glimpses into the lives of the locals.

So whether you’re coming from a nearby town or traveling from across the country, there’s a route that fits your needs and travel style. The key is to plan ahead, pack wisely, and keep your camera ready—because from the moment you start your journey to Sikkim, the views are nothing short of magical.
