The short answer
When to go to Mon
November to March is the most reliable window for Mon, with dry weather, clearer hill views and more dependable roads. Early April brings Aoleang Monyu, the Konyak new-year festival, which is worth planning around but needs early booking and some tolerance for showers. Avoid June to September: monsoon rain brings landslides and long delays on hill roads. For older travellers, the cool, dry months give the best chance of a comfortable journey, and extra buffer days remain sensible even then.
