# Best Time to Visit Sikkim
Sikkim is open year-round but the experience varies dramatically. Monsoon closes roads. Winter closes high passes. Spring brings rhododendrons. Here is every month scored.
The Verdict
**March-May (Spring): 5/5** — Rhododendrons bloom at 3,000m+. Kanchenjunga visible. Roads open. Yumthang Valley flowers. The best season.
**June: 3/5** — Pre-monsoon. Warm but increasingly cloudy. Last window before rains.
**July-September (Monsoon): 1/5** — Landslides close NH10 regularly. Nathu La closed. Tsomgo Lake inaccessible. Avoid.
**October-November: 5/5** — Post-monsoon clarity. Festival season (Dashain, Tihar). Kanchenjunga crystal clear. Best trekking.
**December-February (Winter): 3/5** — Cold but stunning. Snow above 3,000m. Nathu La closed. Gangtok accessible. Pelling views excellent on clear days.
Key Routes
Gangtok: Year-round. Pelling: March-May, Oct-Nov. North Sikkim (Lachung, Yumthang): March-June, Oct-Nov only. Tsomgo/Nathu La: March-June, Sept-Nov.
