Best Time to Visit Sikkim from Kolkata
Sikkim is a year-round destination, but the experience varies by season. From Kolkata, plan with weather, visibility, and road conditions in mind.
- Spring (March–May): Pleasant temperatures (10–20°C). Rhododendrons bloom across Yumthang Valley and Varsey; clear Himalayan views emerge through April–May.
- Early Summer (late May–mid June): Warmer days in Gangtok and Pelling; higher altitudes still cool. Good time for families before monsoon sets in.
- Monsoon (mid June–September): Lush, misty landscapes and fewer crowds, but landslides and intermittent road closures are possible. Travel with buffer days if you love the monsoon mood.
- Autumn (October–November): Crisp skies, excellent mountain visibility, festive vibe post Durga Puja from Kolkata. Ideal for photography and high passes (subject to weather).
- Winter (December–February): Snow chances at Tsomgo, Nathula surroundings, Lachung/Yumthang, and higher reaches. Cold (sub-zero at altitude). Great for snow seekers; keep buffer for weather delays.
Festival highlights: Losar (Feb/Mar), Saga Dawa (May/June), Pang Lhabsol (Aug/Sep). Festivals add color but increase demand—book permits and stays well in advance.
How to Reach Sikkim from Kolkata
The gateway to Sikkim is via Siliguri corridor—by air to Bagdogra or by rail to New Jalpaiguri (NJP), then a scenic road transfer to Gangtok or other bases.
By Air (Fastest)
- Fly from Kolkata (CCU) to Bagdogra (IXB). Typical flight duration ~1 hour 15 minutes.

By Train (Comfort + Value)

By Bus (Budget overland)
- Overnight government or private buses from Kolkata to Siliguri (12–14 hours), then onward road transfer to Sikkim.
Self-Drive/Ride
- Route: Kolkata – NH12 – NH27 – Siliguri – NH10 – Gangtok (~670–700 km). Scenic but long; plan a Siliguri halt.
