Somewhere between the prayer flags fluttering over Tsomgo Lake and the whistle of a hundred-year-old steam engine puffing through Darjeeling bazaar, the Eastern Himalaya casts a spell that no other Indian hill circuit quite matches. Sikkim and Darjeeling sit side by side yet feel like two different worlds — one a spotless Buddhist mountain state where army convoys wind towards the Tibet border at Nathula, the other a colonial-era tea town where Kanchenjunga, the world's third-highest peak at 8,586 metres, fills the horizon on a clear morning. For travellers from Surat, Ahmedabad and Vadodara, the whole circuit runs off a single airport — Bagdogra — and fits beautifully into 6–8 days. If you loved the snow of a Kashmir winter in Gulmarg or the deodar valleys of a Shimla–Manali circuit, consider this the next step east — higher passes, stronger chai and far fewer crowds.
How to reach from Gujarat: fly into Bagdogra, then climb
Bagdogra Airport (IXB), near Siliguri in West Bengal, is the gateway for both Sikkim and Darjeeling. There are no direct flights from Gujarat, so you connect through Delhi, Kolkata or Guwahati — total journey time from Surat or Ahmedabad is typically 6–9 hours depending on the layover, with return fares usually in the ₹9,000–₹16,000 range if booked 4–6 weeks ahead. From Bagdogra, shared and private taxis run everywhere: Gangtok is roughly 120 km and 4–5 hours up the Teesta river valley on NH10, while Darjeeling is about 70 km and 3 hours of switchbacks. A private cab costs around ₹3,500–₹5,500 per transfer depending on season and vehicle. Train lovers can also reach New Jalpaiguri (NJP) on long-distance trains from Mumbai or Ahmedabad, though the 40-plus-hour journey makes flying the sensible choice for a one-week trip. Families planning around school holidays should book Bagdogra flights early — the airport gets genuinely busy in peak season, a pattern familiar to anyone who has priced Andaman flights from Gujarat in May.
Gangtok, Tsomgo Lake and Nathula: permits explained
Gangtok is the most orderly hill capital in India — the pedestrian-only MG Marg has no traffic, no litter and cafes serving thukpa and momos with mountain views. The classic day trip climbs to Tsomgo (Changu) Lake at about 12,400 ft, the sacred Baba Harbhajan Singh Mandir, and finally Nathula Pass on the old India–Tibet trade route at roughly 14,140 ft. Here is the part first-timers miss: this entire route sits in a protected border zone, so you cannot drive up on your own. Tsomgo Lake needs a Protected Area Permit arranged through a Sikkim-registered travel agency or your hotel, usually issued overnight against passport photos and a photo ID (carry your Aadhaar or passport, not just a soft copy). Nathula requires a separate, stricter permit that is issued to Indian nationals only, again solely via registered agencies, and the pass is closed to visitors on certain weekdays — traditionally the start of the week — plus any day the army shuts it for weather or security. Nathula day-trip packages from Gangtok generally run ₹4,000–₹7,000 per vehicle over and above the permit paperwork, and in winter the road can close at short notice after snowfall, so keep a buffer day.

Darjeeling: toy train, Tiger Hill sunrise and tea gardens
Darjeeling earns its 'Queen of the Hills' title the moment the Darjeeling Himalayan Railway — a UNESCO World Heritage line since 1999 — comes chuffing along the main road, close enough to touch. Most visitors ride the two-hour joyride loop from Darjeeling to Ghum, India's highest railway station at about 7,400 ft, pausing at the Batasia Loop where the track spirals around a war memorial garden; steam-hauled seats cost noticeably more than diesel ones and sell out days ahead in season, so book on the IRCTC site before you travel. The other non-negotiable is Tiger Hill: a 4 am taxi ride rewards you with sunrise setting the entire Kanchenjunga massif ablaze, and on exceptional days a faint pyramid of Everest far to the west. Fill the rest of your time with the Himalayan Mountaineering Institute and zoo, the Peace Pagoda, and a walking tour of a working tea estate such as Happy Valley, where a first-flush tasting teaches you why Darjeeling leaf auctions at prices Assam growers only dream about. It is an easy, low-altitude town that older travellers handle comfortably — worth noting if you are planning with the family checklist from our senior citizen parents travel guide.
The 6–8 day circuit, and when Kanchenjunga actually appears
The route that has stood the test of hundreds of Explera departures runs like this: Day 1, fly into Bagdogra and drive to Gangtok; Day 2, Tsomgo Lake and Baba Mandir, adding Nathula if your permit day aligns; Day 3, Gangtok sightseeing across Rumtek Monastery, the ropeway and MG Marg; Day 4, drive four hours to Darjeeling; Day 5, Tiger Hill sunrise, toy train and tea gardens; Day 6, return to Bagdogra and fly home — while 7–8 days lets you add Pelling's Kanchenjunga skywalk or a two-day permit-controlled North Sikkim package to Lachung and the Yumthang Valley, roughly ₹9,000–₹14,000 per person with jeep, stay and meals, on top of a mid-range circuit budget of about ₹28,000–₹45,000 per person before flights. Time it right, because the mountain hides for months: October to December brings glass-clear post-monsoon skies and the best Tiger Hill strike rate, March to May brings rhododendron blooms with growing afternoon haze, and deep winter is snowbound magic at Tsomgo but risks Nathula closures. Avoid June to September outright — this belt records some of India's heaviest rainfall and NH10 is notoriously landslide-prone, so pick from our monsoon travel destinations from Gujarat in those months instead, the way many of our Gujarati family groups do before saving the Himalaya for Diwali. Ambitious travellers also bolt on a land extension, since the region borders two easy international add-ons — see our Nepal travel guide and Bhutan travel guide for how those crossings work for Indian passport holders.
Frequently asked questions
Do I need any permit just to enter Sikkim as an Indian citizen? No — Indian nationals can enter Sikkim freely; permits apply only to protected areas like Tsomgo Lake, Nathula Pass and North Sikkim, and your hotel or tour operator arranges them overnight against photo ID and passport photos. Foreign nationals, however, need an Inner Line Permit-style Restricted Area Permit even for Gangtok.
Can foreigners or OCI card holders visit Nathula Pass? No — Nathula is open to Indian citizens only. NRI friends and family travelling on foreign passports can still do Gangtok, Tsomgo Lake (with the right permit) and all of Darjeeling; check the paperwork basics in our India entry documents guide for NRIs and OCI holders before they fly.
Is the toy train worth it, and how do I book? Yes, at least once — the steam joyride from Darjeeling to Ghum via Batasia Loop is a bucket-list ride on a UNESCO heritage railway. Book on IRCTC like any train ticket, choose steam over diesel if the fare difference doesn't pinch, and reserve early for October–December and April–May departures.
