Nepal is safe to travel in September 2025

Nepal has been recognized as the happiest country in South Asia according to the UN's World Happiness Report, attributed to its response to the Covid-19 pandemic.

Despite the challenges posed by the crisis, this mountainous nation managed to maintain a sense of peace and contentment. Additionally, Nepal became a refuge for digital nomads and individuals seeking to escape the turmoil of recent conflicts. Following the pandemic, the tourism industry in Nepal experienced a rapid recovery and has since been operating smoothly. With fewer tourists, affordable prices, and favorable weather conditions, September 2025 is an ideal opportunity to explore Nepal.
