September month in Nepal usually has nice and clean weather. However, during the last few years, Nepalese have experienced challenging yet non-stop rain during the whole month. However, rain in Nepal usually takes place during nighttime and thereby, leaves the sky clean and nice during the morning time as well as partially cloudy during days.
Hence, during September, you may opt to perform trekking in Nepal in some specific areas, such as Annapurna Base Camp, Ghorepani Poonhill and Jomsom Muktinath to achieve a dramatic trekking experience for the whole month. Particularly, individuals may perform trekking activities in the following trek regions in the month of September.
Upper Mustang Trek, known popularly as the hidden world of the ancient kingdom of Buddhist is at the top from the list of areas experiencing relatively less rainfall in Nepal, while Pokhara valley is the highest in the list. Because of this, Upper Mustang remains in the top position based on rain shadow trek in the country.
Even during the monsoon rains starting from June to August, you may easily trek here via entire mountain trails with comfort and ease. Our Nepal Tours Travel recommend to perform trekking for the whole month of September in the upper Mustang region starting from Kagbeni to up to Lomangthang and come back to Kagbeni.
Annapurna Circuit Trek is in the second number among the best treks available for individuals in September. Here, you will trek across Manang valley i.e. at other side of the Upper Mustang region and is a rain shadow area of the country.
Narphu Valley trek also involves trekking in the restricted area because of its close proximity and remoteness towards Tibet. Nar and Phu are the two different villages belonging to further northern areas of Ghyaru and Ngawal leaving the Annapurna Circuit trail. While at the end of this trek, you may continue moving towards Annapurna Circuit or opt to descend back towards the starting point of your trek and retrace towards Kathmandu. In the past, it requires an organized trek, but recently, you will find a home stay or a teahouse type of trek as sufficient to come up with the basic accommodation.
