The best months are March to May and October to early December, when skies are clearest and Kanchenjunga shows itself most reliably. Spring brings rhododendron and orchid blooms; autumn brings crisp, post-monsoon clarity and big mountain views. The monsoon (roughly mid-June to September) is lush but landslide-prone, and roads to high passes can close, while winter (December to February) is cold, quiet, and sometimes snowy up high. Time a visit around Losar (Tibetan New Year, usually February) or the Pang Lhabsol festival honoring Kanchenjunga (around August-September) for masked dances and ceremony.

The nearest airport is Pakyong (PYG), about 30-40 km and roughly 1.5 hours from Gangtok, though flights are limited; many travelers instead fly into Bagdogra (IXB) near Siliguri and take a shared or private taxi for the scenic 4-5 hour drive up. The closest major railhead is New Jalpaiguri (NJP). In town, MG Marg and the central area are best explored on foot (it is largely pedestrianized), while shared taxis and private cabs handle the steep outer hills; app-based ride-hail is essentially nonexistent, so use registered local taxis and agree on fares. For day trips to lakes and passes, you must hire a permitted vehicle through a registered Sikkim tour operator.
