Why visit Nepal in September
The arrival of September means the beginning of the autumn tourist season in Nepal, which lasts until the end of November. Here are a few of the many reasons why you should visit Nepal in September despite the relatively wet weather.
- Peaceful trails: Since the trekking season does not reach its peak until October, the number of trekkers in September is comparatively low. Therefore, it is one of the most suitable times to enjoy trekking and hiking in Nepal. Going on a trek to Mardi Himal, Poon Hill, or going on a Langtang Valley trek during this time allows for a more peaceful and relaxing experience compared to going during October and November.
- Crystal-clear vistas: The highlight of every trip to Nepal is the beauty of the country. Hills are verdant after monsoon during September and mountains—sans smoke and pollution—glisten in the warm afternoon sun. September is one of the best times to take in the country’s natural beauty, especially from its hill-top towns like Nagarkot and Bandipur.
- Festive season: September is also the month when the festive season kicks off in Nepal. The whole country prepares to celebrate Dashain, the most revered and anticipated festival in the country’s calendar. This makes September a great time to experience Nepalese culture. Make sure to take part in celebrations and fly kites with locals while you are there.
- Rafting opportunities: Nepal’s major rivers flow downhill from the Himalayas. Their current reaches its peak during monsoon and subsides with the end of the rainy season. Make sure that you grab this chance and go on a rafting or kayaking trip in one of the country’s numerous rivers
Where to go and what to do
In addition to some of the most popular trekking routes in the world, Nepal in September offers an expansive range of choices for travelers of all kinds. If you are looking to delve into the more cultural side of the country, a trip to Lumbini along with an exploration of the Kathmandu Valley should definitely be on your list. Marvel at the ornate architecture of stupas, temples, and monasteries that the country is known for. Then go on a safari trip in Chitwan National Park, home to some of the most endangered animal species on the planet, including the magnificent Royal Bengal tiger. Ride a canoe through its river and spot crocodiles and alligators along the way. For more ideas, make sure to go through our travel guide on the things to do while in Nepal.
As with the other months of the year, traveling to Nepal in September has its own set of benefits, like fewer crowds and a cleaner atmosphere. However, Nepal is a country that is rich in history, culture, cuisine, and landscape — all of which make it an ideal, year-round destination.
