Pakyong (PYG) opened in 2018 as Sikkim's first airport but operational reliability has been challenging. Most Sikkim-bound travellers in 2026 still use Bagdogra (IXB) as the practical entry. Here is the honest comparison and the road onward to Gangtok and Pelling.
Two airport choices for Sikkim — and why both have caveats
Sikkim is one of the smallest Indian states by area but among the most geographically dramatic. The state has historically had no commercial airport — visitors relied entirely on Bagdogra Airport (IXB) in West Bengal as the air entry point, with a 4 to 5 hour road journey onwards to Gangtok or Pelling. This changed in October 2018 with the opening of Pakyong Airport (PYG), perched at 1,372m elevation on a mountainside 30 km south of Gangtok.
The promise of PYG was a 30 minute road transfer to Gangtok and elimination of the long IXB-Gangtok drive. The reality has been more complex. PYG's location, runway specifications and weather profile have resulted in operational completion rates that are meaningfully below typical Indian commercial airports. Through 2024 and 2025, monthly completion rates at PYG varied between 50 and 75 percent, with monsoon months (June-September) sometimes dropping below 50 percent.
For Sikkim-bound travellers in 2026, the practical reality is that Bagdogra remains the primary air entry for the state despite the existence of PYG. Most travel agents and tour operators still recommend IXB as the first choice with PYG as a secondary option for travellers willing to absorb the operational risk for the time saving. This guide structures the comparison and walks through the onward road realities to Gangtok and Pelling.
Pakyong Airport (PYG) in 2026 — schedule, fleet and reliability
By mid-2026 PYG is served by SpiceJet, IndiGo (limited), and occasional Alliance Air flights. The standard schedule is 2 to 4 daily flights from Delhi (DEL-PYG) and 1 to 2 daily from Kolkata (CCU-PYG). Other routes have been launched and suspended over the years — Mumbai, Hyderabad, Bagdogra (yes, an inter-state hop) have all appeared and disappeared from the schedule based on demand and operational sustainability. The aircraft type is Q400 turboprop or ATR 72 — no jet aircraft serve PYG due to runway and approach constraints.
The fares on DEL-PYG typically clear 5,500 to 12,500 rupees one-way in shoulder season and 9,500 to 18,000 rupees in peak (April-June and October-November when Sikkim is at peak tourism demand). The fares are materially higher than DEL-IXB on equivalent dates, reflecting both the cost of the smaller turboprop operation and the route premium.
The operational reliability is the structural issue. PYG sits on a tabletop runway carved into a hillside, with monsoon cloud build-up creating frequent low-visibility events. Winter fog at Delhi origin combined with PYG weather creates double-jeopardy. The completion rates are honestly mediocre — booking PYG without a backup road plan from IXB is a calculated risk. Most experienced Sikkim tour operators book clients on IXB by default and treat PYG as a small bonus when it works.
Bagdogra Airport (IXB) — the reliable workhorse
Bagdogra Airport (IXB) in West Bengal is the practical air gateway for Sikkim, north Bengal hill stations (Darjeeling, Kalimpong) and Bhutan border crossings. By mid-2026 IXB has 60 to 90 daily commercial movements served by all major Indian carriers — IndiGo (the volume leader), Air India, Air India Express, SpiceJet, Akasa, and Alliance Air. The route network covers all metros (DEL, BOM, BLR, MAA, HYD, CCU) and key Tier-2 cities.
The DEL-IXB schedule offers 6 to 9 daily flights, block time around 2 hours 10 minutes, fares typically 4,500 to 8,500 rupees in shoulder season and 7,500 to 14,000 in peak. BOM-IXB has 3 to 5 daily, block time 2 hours 50 minutes, fares 5,500 to 10,500 rupees. CCU-IXB is a 1 hour 5 minute hop with frequent service. The schedule is deep enough to give meaningful choice on departure times — early morning, mid-morning, afternoon and evening options on most days.
The reliability is the structural advantage. IXB operates with much better completion rates than PYG — typically 90 to 95 percent in good weather months and 80 to 85 percent in monsoon. The road from IXB to Gangtok (132 km) takes 4 to 5 hours via NH-10 along the Teesta valley. Pre-paid taxi cost is 4,500 to 6,500 rupees for a Bolero or Innova one-way. Shared taxis to Gangtok are available at 350 to 550 rupees per seat with 4 to 6 daily departures. For onward routes from IXB, see our Delhi to Bagdogra route options.
The IXB to Gangtok road in 2026 — Teesta valley reality
The IXB-Gangtok road journey via NH-10 follows the Teesta river valley through Sevoke, Rambhi, Tista Bazar, Kalijhora, Rangpo (the West Bengal-Sikkim border) and onwards to Singtam and Gangtok. The 132 km route takes 4 to 5 hours under normal conditions, 5 to 7 hours during peak weekend traffic, and can extend to 8+ hours during monsoon landslide events.
The road condition through 2025-2026 is mostly good with the BRO and PWD upgrades, but the Teesta valley stretch is fundamentally vulnerable to monsoon damage. The catastrophic flood events of October 2023 caused major road damage that took months to repair fully. Even in non-flood years, the July-September monsoon period sees frequent landslide-driven delays. The road is operable year-round but with weather risk.
The Sikkim entry checkpoint at Rangpo is the formality point. Indian travellers need to register at the checkpoint with Aadhaar and tourist details (no formal permit but a registration). Foreign nationals need a Restricted Area Permit (RAP) for Sikkim, which is essentially a state-entry registration system; the RAP can be obtained at Rangpo with passport, Indian visa and 2 photos same-day. The process takes 30 to 60 minutes typically. For permit guidance, see our Inner Line Permits guide.
Gangtok — capital city as base for Sikkim exploration
Gangtok at 1,650m elevation is the capital and administrative centre of Sikkim, serving as the natural base for travellers exploring the state. The city is built across multiple ridgelines with the famous MG Marg (Mahatma Gandhi Marg) as the pedestrian-only commercial spine. The Tashi viewpoint offers Kanchenjunga views on clear mornings (typically pre-7 AM in summer, pre-9 AM in winter).
Accommodation ranges from budget hotels around Tibet Road and MG Marg area (1,500 to 3,500 rupees) to mid-tier properties along the Hill Cart Road and Deorali (3,500 to 7,500 rupees) to luxury options like Mayfair Spa Resort and Elgin Nor-Khill (12,000 to 35,000 rupees). The Mayfair Gangtok and the Elgin properties in particular are recommended for first-time visitors wanting full-service Sikkim luxury.
From Gangtok, the standard day trips include Tsomgo Lake (also called Changu Lake) at 3,780m with a yak ride and the high-altitude Hindu shrine — requires a permit obtainable through tour operators, and is altitude-sensitive. Nathu La Pass at 4,310m on the India-China border requires more elaborate permits and is accessible certain days of the week. Rumtek Monastery (24 km from Gangtok) is the seat of the Karmapa and a major Tibetan Buddhist site. The Ranka Monastery is closer and equally photogenic.
Pelling and West Sikkim — the Kanchenjunga viewing base
Pelling at 2,150m elevation in West Sikkim is the second major tourist base after Gangtok, specifically positioned for Kanchenjunga viewing. The Pelling town stretches across Upper Pelling and Lower Pelling, with most tourist accommodation in Upper Pelling for the better mountain views. The Sangachoeling and Pemayangtse monasteries are the cultural highlights; the Singshore Bridge (one of Asia's highest) and the Khecheopalri Lake (sacred wishing lake) are the natural attractions.
Pelling is 134 km from Gangtok by road, taking 5 to 6 hours via Ravangla. The alternative direct route from IXB is 158 km taking 6 to 7 hours via Jorethang and Geyzing. Most Sikkim itineraries cover Gangtok plus Pelling as a 5 to 7 day circuit — typically 2 to 3 nights Gangtok, 1 to 2 nights Pelling, with day trips from each base. The road quality has improved through 2024-2025 with NH-510 upgrades, but Pelling remains a longer road journey than first-time visitors expect.
Kanchenjunga (8,586m, the world's third-highest peak) is visible from Pelling on clear mornings. The Pelling Sky Walk (a glass-floored walkway at the Chenrezig statue) is a recent addition that has become a popular photo stop. The Khangchendzonga National Park, a UNESCO World Heritage site, is partially accessible from West Sikkim. Yuksom, the historic first capital of Sikkim 33 km from Pelling, is the trailhead for the Goecha La trek and a peaceful village stay alternative to Pelling.
North Sikkim — Lachung, Yumthang, Gurudongmar realities
North Sikkim is the most scenically dramatic part of the state but the most logistically demanding. The standard 3-day North Sikkim circuit covers Gangtok-Lachung (130 km, 6 to 7 hours), Lachung-Yumthang Valley (24 km, 90 minutes) and Lachung-Lachen-Gurudongmar Lake (172 km, full day with 5,210m altitude exposure). The entire North Sikkim circuit requires a Protected Area Permit obtained through registered tour operators in Gangtok — Indians need 2 days advance with Aadhaar, foreigners need RAP plus additional permits.
Lachung at 2,750m and Lachen at 2,750m are the village staging bases. Yumthang Valley at 3,575m is the Valley of Flowers, best visited April-June for the rhododendron and primula blooms. Zero Point (4,724m) beyond Yumthang is the road end during winter snow season. Gurudongmar Lake at 5,210m near the China border is the highest tourist-accessible lake in India, with severe altitude exposure for sea-level visitors.
The North Sikkim road network is fundamentally vulnerable to weather and landslides. Roads can close suddenly for 1 to 3 days. The 2023 monsoon damage required extensive rebuilding, with sections only fully restored through 2024-2025. Most North Sikkim tours sell as fixed-itinerary packages through Gangtok-based operators (typical pricing 8,500 to 14,500 rupees per person for 3 days including accommodation, vehicle, permits and meals). For altitude considerations on the Gurudongmar leg, see our altitude sickness guide.
Booking strategy — fares, timing, monsoon avoidance
For most Sikkim trips in 2026, the practical booking pattern is to fly into IXB as the default, treat PYG as an optional time-saver when fares and weather align favourably, and build a 2-day buffer at the start of the trip for any weather-related delay on the inbound. Avoid June to mid-September for trips dependent on North Sikkim or Pelling road quality — the monsoon road risk is real.
The peak Sikkim seasons are March-June (spring greenery and rhododendron blooms in North Sikkim) and October-November (post-monsoon clear weather and Kanchenjunga visibility). Winter (December-February) has clearer mountain views and lower demand at Gangtok and Pelling, but North Sikkim circuits are heavily snow-restricted. December 22 to January 5 sees premium rates for the Christmas-New Year window even though high-altitude circuits may not be operational.
Fare optimisation is mostly about advance booking. DEL-IXB and BOM-IXB at 6 to 8 weeks out usually clear at the bottom of the seasonal fare band. PYG fares benefit less from advance booking because the route operates at thinner load factors and prices are more demand-driven. Round-trip booking on IndiGo or SpiceJet for the IXB leg typically offers small discount versus separate one-ways.

Frequently asked questions
Is Pakyong Airport (PYG) reliable enough to book for a fixed Sikkim itinerary?
Honestly, no for fixed itineraries. PYG operational completion rates range from 50 to 75 percent monthly, dropping below 50 percent in monsoon. The reliability is structurally constrained by the airport's mountain location and weather profile. For trips with fixed commitments at Gangtok or Pelling (hotel bookings, North Sikkim tour starts), Bagdogra (IXB) is the safer entry. PYG is best treated as a bonus option for flexible itineraries that can absorb a cancellation with a same-day IXB pivot.
How long is the road journey from Bagdogra (IXB) to Gangtok?
The IXB-Gangtok road via NH-10 along the Teesta valley is 132 km and takes 4 to 5 hours under normal conditions. Monsoon season (June-September) can extend this to 5 to 7 hours with landslide delays, and major flood events have closed the road for days at a time. Pre-paid taxis at IXB charge 4,500 to 6,500 rupees for a Bolero or Innova one-way. Shared taxis are available at 350 to 550 rupees per seat with multiple daily departures from the airport area.
Do Indians need a permit to visit Sikkim?
Indian citizens do not need a formal permit for Sikkim but must register at the Rangpo entry checkpoint with Aadhaar and tourist details. This is a simple registration process taking 5 to 15 minutes. For North Sikkim circuits (Lachung, Lachen, Gurudongmar Lake area), a Protected Area Permit is required, applied through registered tour operators in Gangtok with 2 days advance notice. Tsomgo Lake and Nathu La day trips also require permits handled by tour operators. Foreign nationals need a Restricted Area Permit (RAP) obtainable at Rangpo with passport, Indian visa and 2 photos.
When is the best time to visit Pelling for Kanchenjunga views?
October to November is the best window for clear Kanchenjunga visibility — post-monsoon clear weather, stable atmosphere, low cloud cover. March to April is the second-best window with spring weather and reasonable visibility. May-June sees increasing cloud cover from approaching monsoon. June to September is monsoon season with consistently poor visibility. December-February has clear weather but is cold and some accommodation operates at reduced capacity. The early morning window (typically pre-7 AM) gives the best Kanchenjunga visibility regardless of season.
Can I visit Gurudongmar Lake without proper acclimatisation?
Strongly discouraged. Gurudongmar Lake at 5,210m is one of the highest tourist-accessible points in India. The lake is typically visited as a day trip from Lachen (2,750m), which means a same-day altitude jump of 2,460m. Acute Mountain Sickness incidence on Gurudongmar day trips is high. Travellers with prior altitude experience may handle it; first-time high-altitude visitors should consider skipping Gurudongmar or only proceeding after 24-48 hours at Lachen. Carry Diamox after physician consultation, drink plenty of water and descend immediately if symptoms worsen.
What is the typical Sikkim trip duration?
A standard Sikkim itinerary is 5 to 7 days. A 5-day trip covers Gangtok (3 nights) with day trips to Tsomgo Lake and Rumtek, then Pelling (1 night) for Kanchenjunga views. A 7-day trip adds Yuksom (1 night) and a North Sikkim 2-day circuit (Lachung-Yumthang). A 10-day Sikkim plus Darjeeling combination is also popular. Add 2 days for IXB road approach (1 day each way) on top of the in-state itinerary.
Is Sikkim road travel safe in monsoon season?
Partially. The main Gangtok and Pelling areas remain accessible in monsoon but with increased weather delays and landslide risk. North Sikkim circuits (especially the Gurudongmar Lake area) are at significantly elevated risk during monsoon and many tour operators do not operate these circuits between mid-June and mid-September. The Teesta valley road (NH-10) is operable but with 1 to 3 hour weather delays common. For non-essential monsoon Sikkim travel, the right approach is to focus on Gangtok plus Pelling without committing to North Sikkim, and to build 2 to 3 day buffers either side of fixed commitments.
Are there direct flights from Bangalore or Mumbai to Pakyong (PYG)?
Not as direct scheduled services in 2026. PYG is connected to Delhi (DEL) and Kolkata (CCU) as the standard routes, with other origins requiring a connection through these cities. The schedule has historically been volatile — Mumbai and other routes have been launched and suspended multiple times. From BLR, HYD, MAA, BOM the practical pattern is to fly to Bagdogra (IXB) directly, where the route network is much deeper, and take the 4-5 hour road to Gangtok rather than attempting a PYG connection.
