# Best Time to Visit Arunachal Pradesh
India's wildest frontier state. Inner Line Permits required for all visitors. Roads are an adventure in themselves. Timing is everything.
The Verdict
**October-November: 5/5** — Post-monsoon clarity. Tawang Pass open. Festival season (Torgya at Tawang monastery). Roads at their best. 10-20°C.
**March-April: 5/5** — Spring bloom. Sela Pass usually clear. Ziro Valley preparing for rice planting. Losar festival.
**December-February: 3/5** — Cold. Snow closes Sela Pass intermittently (Tawang access cut). But Ziro, Pasighat, Mechuka accessible. Clear mountain views.
**May-June: 2/5** — Pre-monsoon heat at lower altitudes. Increasing cloud cover. Last window before rains.
**July-September: 1/5** — Monsoon devastation. Landslides routine. Sela Pass closed weeks at a time. Do not plan travel.
