Gangtok by road: up the Teesta into Sikkim with your own driver

How do you get to Gangtok by road from Siliguri?

Gangtok is a mountain capital with manners. The city climbs up a ridge at around 1,600 metres, its central boulevard, MG Marg, is closed to traffic and kept spotless, and the monasteries on the surrounding hills ring with horns and cymbals at dawn. On clear winter mornings Kangchenjunga fills the northern sky. For most visitors it is also a base: from here you go up to Tsomgo Lake and Nathu La, north to Lachung and Yumthang, or west to Pelling and the Kangchenjunga viewpoints.

The road there is part of the adventure and part of the challenge. NH 10 follows the Teesta through a steep gorge where landslides and river damage are a fact of life, the state border brings a checkpost, and Sikkim has its own rules for tourist vehicles and protected areas. A chauffeur who drives this road every week knows which of those rules matter to you, and when to leave to avoid the jams. This guide explains the route, what to see, permits, seasons, and exactly what RutzIndia.com charges.

What to see in and around Gangtok

• MG Marg: the pedestrian heart of town, lined with cafes, momo shops and handicraft stores, busiest in the evening.
• Enchey Monastery: a small, atmospheric monastery on a ridge above town, famous for its masked dances in winter.
• Rumtek Monastery: about 24 km from Gangtok across the valley, the large seat associated with the Karma Kagyu lineage, with a monastic college and fine prayer halls; carry ID for the security check at the entrance.
• Namgyal Institute of Tibetology and Do Drul Chorten: a museum of thangkas, manuscripts and ritual objects, and a great white stupa ringed with prayer wheels, both close to each other.
• Ganesh Tok, Hanuman Tok and Tashi Viewpoint: hilltop viewpoints over the city and, weather permitting, the Kangchenjunga range.
• Banjhakri Falls and Energy Park: a landscaped waterfall park with shaman-themed sculptures, good with children.
• Gangtok Ropeway: a short cable car ride over the city, weather and maintenance permitting.
• The Flower Exhibition Centre: orchids and seasonal blooms near the Ridge Park.

For food, momos and thukpa are everywhere; try sha phaley, local churpi (hard cheese) and, if you are brave, a meal with dalle chillies. Official destination information and notices are on Sikkim Tourism.

The road: NH 10 through the Teesta gorge, and the alternate corridor

NH 10 via Sevoke, Melli, Rangpo and Singtam (about 115 km from Siliguri). From Siliguri or Bagdogra your chauffeur heads through the Sevoke forests, crosses the Coronation Bridge and follows the Teesta upstream past Kalijhora, Teesta Bazaar and Melli, where the West Bengal and Sikkim sides meet. At Rangpo you cross into Sikkim at the border checkpost; foreign nationals complete their permit formalities here. The road continues along the Rangpo and Teesta valleys through Singtam and Ranipool before the final climb into Gangtok.

This highway has been badly affected by landslides and river erosion, most dramatically after the Teesta flash flood of October 2023, and in the monsoon sections can close without notice. On a normal day expect four to five hours; on a bad day, much longer.

The alternate corridor via Lava, Rhenock and Pakyong. When NH 10 is shut, drivers switch to the hill route through the Dooars and Kalimpong district, climbing via Gorubathan and Lava, then entering Sikkim near Rhenock and approaching Gangtok via Pakyong. It is slower and longer, but it is often the only way through in the rains. The newer highway along this corridor has been under development to give Sikkim a second lifeline.

Road notes from our drivers:

• Start early from Bagdogra or Siliguri, ideally by 9 am, to reach Gangtok in daylight.
• Rangpo: queues at the check can be long in peak season; keep ID handy for every passenger.
• In the city: Gangtok has strict one-way systems, parking rules and restrictions on vehicles in the centre. Drop-off points are designated, and some local sightseeing is organised around Sikkim-registered taxis; we plan accordingly.
• Fuel in Siliguri or Rangpo.

Permits and vehicle rules you should know

Sikkim is welcoming, but it is a border state with Protected Areas. The key points, which you should confirm on the official site before travelling:

• Indian citizens do not need a permit to visit Gangtok, but do need a Protected Area Permit for places such as Tsomgo Lake, Nathu La and North Sikkim (Lachung, Yumthang, Lachen). These are normally arranged through registered local tour operators with photos and ID.
• Foreign nationals need a Restricted Area Permit to enter Sikkim at all, issued at entry points such as Rangpo and via official channels, and further permits for some protected areas; certain places, notably Nathu La, are closed to foreigners. The official summary is on the Sikkim Tourism Restricted Area Permit page.
• Vehicles into protected areas are generally Sikkim-registered tourist vehicles operating under the permit. Our car brings you to Gangtok; for Tsomgo, Nathu La and the north, our desk books the permit and a local permit-holding vehicle, which is why those trips are quoted separately.

Best time to visit Gangtok

• March to May: spring, with rhododendrons and magnolias in the hills and pleasant days; also the busiest season with families from across India.
• October to mid-December: clear skies after the monsoon and the best mountain views; Durga Puja and Diwali are packed.
• Late December to February: cold, often very clear; snow blocks higher roads such as Nathu La at times, and Losar, the Tibetan New Year, brings celebrations.
• June to September: heavy monsoon, frequent landslides on NH 10 and cloud-covered peaks. Travel with a buffer day.

Sikkim's festivals, Losar (February or March), Saga Dawa (May or June), Pang Lhabsol (August or September) and Losoong (December), are worth timing a visit around.

• Airport pickup at Bagdogra with flight tracking and a name board: an hour of waiting is included after international flights and half an hour after domestic ones. Airport information for Sikkim's own Pakyong airport is on the AAI site, though commercial flights there have been limited and intermittent, so most guests still fly to Bagdogra.
• One-way drop from Siliguri, NJP or Bagdogra to your Gangtok hotel, and a separate drop back.
• Round-trip Sikkim and Darjeeling tours with one car for the non-protected sectors.
• Gangtok to Pelling and other West Sikkim transfers; see Pelling by road.
• Tempo Traveller for groups; see Tempo Traveller on rent.
• Permit trips to Tsomgo Lake and Lachung and Yumthang, arranged through the desk with local vehicles.

Apart from the sedan, the 115 km per-km total for each vehicle sits under its class floor, so the one-way column shows the minimum fare for the Ertiga, Innova, Fortuner and Tempo Traveller. On top of these base figures come 5% GST, the tolls, parking and permit fees you actually incur (billed as paid), and for multi-day tours a night allowance of Rs 1,500 for the chauffeur. A tour day is never billed below 250 km. Protected-area excursions in local vehicles are quoted separately. Our cars are within four model years. Free cancellation runs until 72 hours before pickup; after that we keep 10%, then 50% once you are inside 48 hours, and the whole amount inside 24 hours or on a no-show, as written in our cancellation policy. When NH 10 is closed, we reroute first and talk charges later.

Book a Bagdogra to Gangtok car

A four-day Gangtok plan

Day one, Bagdogra to Gangtok (about 125 km). Land by late morning, lunch at Melli or Rangpo, reach Gangtok by late afternoon and walk MG Marg in the evening.

Day two, Tsomgo Lake and Baba Mandir (about 80 to 110 km in a permit vehicle). Early departure for the high road to the glacial lake at about 3,700 metres, with Nathu La for Indian citizens when open. Back in Gangtok by afternoon.

Day three, Gangtok sights (about 50 km). Rumtek in the morning, then the Institute of Tibetology, Do Drul Chorten, Enchey and a viewpoint for sunset.

Day four, onward or home (about 115 to 130 km). Drive back to Bagdogra, or west to Pelling for Kangchenjunga views, or plan a two-night permit trip north to Lachung. Darjeeling and Kalimpong pair well too: see Darjeeling by road and Kalimpong by road.

Practical tips

• ID and photos: carry originals and copies of photo ID for everyone, plus passport photos for permits.
• Altitude: Gangtok is comfortable, but Tsomgo and Nathu La are high; go slowly and avoid alcohol the night before.
• Plastic: Sikkim is strict about waste and single-use plastic; carry a refillable bottle.
• Monastery etiquette: walk clockwise, ask before photographing, dress modestly.
• Motion sickness: the gorge road is winding; sit up front, eat light and ask for a stop at Melli, where the Teesta and Rangit rivers meet below the road.
• Booking: pay by card or UPI when you book online. For a long road trip from Kolkata all the way up, see outstation cabs or our one-way taxi fares.
