Pre-monsoon (April–May) for rhododendron blooms and clear views; post-monsoon / autumn (September–November) for stable weather and excellent visibility. Monsoon (June–August) brings heavy rain and leeches in lower zones; winter (Dec–Feb) is very cold with many high passes closed.

Strong altitudinal variation: subtropical to temperate in lower valleys, cold alpine and glacial conditions at higher elevations. Expect large diurnal temperature swings, cold nights at altitude, and rapid weather changes (snow possible at higher camps outside summer).

Access requires permits. Domestic and foreign visitors must register and obtain permits from Sikkim Forest Department / Tourism offices; foreigners need Restricted Area Permits/Protected Area Permits for certain zones. Trekking into core areas requires park permits, guide and sometimes porterliaison through registered operators. Fees vary by nationality, zone and season—check current fees with the Sikkim Forest Department or authorised tour operators. Visitor centres and forest offices have working hours during daytime; trekking is season-dependent.

Nearest airport: Bagdogra (IXB) ~170–200 km by road to Gangtok/Yuksom (road travel 5–7+ hours depending on sector). Nearest major railhead: New Jalpaiguri (NJP). Road access to trailheads: Yuksom (west) for Goecha La/Dzongri, Lachen/Lachung for northern approaches. Many trekking trails start at remote trailheads reached by jeep or shared taxis; road conditions can be rough and weather-dependent.

For a meaningful experience: 7–12 days for Goecha La/Dzongri circuits; shorter visits to buffer-zone attractions and cultural sites: 2–4 days. Northern sectors (Lachung/Lachen) may need additional days for acclimatisation and travel.

Layered clothing system: thermal base layers, insulating mid-layers (fleece/down), waterproof windproof outer shell, warm hat and gloves, sturdy high-ankle trekking boots, gaiters, sunhat and sunglasses, sunscreen, sleeping bag rated for cold nights, trekking poles, and a basic first-aid/altitude-sickness kit. Bring cash, permit copies and a charged power bank.

Try local dishes such as momos, thukpa, gundruk, and yak-based products in high valleys (yak cheese/chhurpi). Souvenirs: handwoven woolens, prayer flags, traditional Sikkimese handicrafts, thangka paintings and locally produced honey or herbal teas. Respect religious items and request permission before photographing people or sacred objects.
