The Upper Mustang region is a great destination throughout the year, but the best time to visit depends on your preference. Upper Mustang experiences four distinct seasons, each providing a unique experience and opportunity to explore the region. Autumn and Spring are the perfect times to visit as the weather is mild, the sky is clear, and the rhododendrons are in full bloom. Summer is also ideal due to the sunny days and the Tiji festival, which takes place during summer. Additionally, the winter season is favorable for those seeking fewer crowds and a crisp mountain air experience.
