The month of September begins the autumn season by leaving behind the summer monsoon. Autumn is the main trekking fall in Nepal, so it is a perfect time to trek to the Manaslu circuit. It can be some rainy days during the first two weeks of September in the lower region, but it does not regularly rain.

Fewer Trekkers

Manaslu region is a restricted area, so trekkers need to have three different trekking permits and must hire a guide, so there are fewer trekkers compared to the other commercial trekking routes. September is the beginning of autumn, so there are obviously few visitors than in October and November on the Manaslu circuit trek.

Two Different Weather Conditions

You can feel two different weather conditions during the September Manaslu circuit trek. The first two weeks of this month feel like monsoon weather with a few rainfalls and the last two weeks offer nice and clear autumn weather.

Unreal Views

Usually, the days will be bright in September, so you can see mesmerizing views of the high mountains, green hills and more this month. You can see beautiful mountains all the time after the Lho Gaun for a few days in the September Manaslu circuit trek.

Greenery Everywhere

Monsoon rains during the summer season from June to August provide lots of water for the vegetation. The trees and herbs changed to dark green from summer and still look beautiful in September. Cider, needlewood, and other trees in the lower region and pine, oak, juniper and other trees with dense shrubs look beautiful in the Manaslu region in September.

Easy to Cross Larke La

September also welcomes lots of festivals in Nepal. You can see Teej (women's festival), Indra Jatra, and other festivals during the Manaslu circuit trek in September. The festival in September provides an extra memorable experience for you.

Manaslu Circuit Trek Preparation in September

September is the beginning of autumn, which is the busiest trekking season in Nepal and also for the Manaslu circuit. You are going to the high Himalayan region, so you need to prepare well to succeed in this adventure trip.

You need to be physically and mentally prepared to trek in such a highly elevated region. Mental preparation means reading well about difficulties and what to do for a successful trip. And Physical preparation is all about stamina and exercise.

Mental Preparation

Manaslu circuit trek is an adventure trek with a high pass Larke La (5,106m). It might not be an easy trip in the Nepalese Himalayas, so you need to be mentally prepared before planning to trek on this route. You better need to find out the difficulties, that you will face on the trek and be ready to tackle them.

Strong mind make-up provides you more confidence to short out every challenge on the trek. Self encourages and a concerned mind support the successful trip by leaving all the doubt far behind, so think that yes, I can do it.

Physical Preparation

Besides the mental preparation, an important part of the trek to the Manaslu circuit in September is the physical preparation. The Manaslu trek is an adventure trek, so being physically fit plays a vital role in this trip. You can do some physical exercise in the club and do some hikes to be physically prepared for this Larke pass trek. Some short treks above 3,000m anywhere in the Himalayas keeps you physically fit for this adventure trek.

Face Late Monsoon Weather

You might feel late monsoon weather until mid-September. You might have some rainy days during the trek until the half of September, but it won’t rain continuously like in a monsoon. The rivers, waterfalls and streams stay bigger and look attractive. The second half of September brings autumn, so the weather will be nice and clear.

Long Trekking Camps

The trekking camps are long for a few days in lower areas. There are lots of up and down hills trails, so it can make a tiring walk. You need to cross several streams on temporary wooden bridges at other times. They might not available because of floods and then need to take a longer route through permanent bridges sometimes.


You might suffer from dehydration during the Manaslu circuit trek in September. The lower region will be warm and sweat a lot because of lots of uphill trails. Because of losing sweat, you might be dehydrated.

Altitude Sickness

It will be fewer chances of altitude sickness because you start the trek from a low elevation, and then ascends gradually to a higher elevation. Although, you might feel the altitude effect after 3,000m of elevation. You will mainly feel altitude when you go for the Larke La pass rather than the other days during the Manaslu circuit trek in September.


You might be tired due to the long camps and altitude effects during the trek. You need to walk 7-8 hours per day in the lower regions, so long camps with lots of up and down hills make you tired. Besides the long trekking days, altitude also can be a cause of tiredness on the trek.

Difficulty of Accommodation

You will get accommodation easily in most of the places, but places like in Deng, Namrung, Lo Gaun, Samdo and Darmasala might be difficult to get enough space. Do not expect luxury accommodations and a room with an attached bath during the trek. But, you can get private accommodation everywhere.

Slippery trails

Due to some rain drops, the trekking trails can be slippery sometimes during the Manaslu trek in September. Although, it should not be slippery on the whole trip except for some spots. Actually, there will be less rain in the higher areas compared to the lower areas.
