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.

Unduly rainfall during monsoon clears air pollution. So the days in September stay bright, and the vegetation looks dark green up in the Manaslu region. You can see attractive waterfalls, rivers, valleys, bright mountains, beautiful lakes, wildlife, and more during the Manaslu Circuit Trek in September.

It will be a smooth temperature in the Manaslu Region in September, although it will be a warm sub-temperate climate in the lower areas at the beginning of the trek. There won’t be snow and ice on the Larke Pass trail in September, so it will be easy to cross this high pass.

Great views of the Manaslu Himalayas, such as Mount. Manaslu, Nadi Chuli, Himal Chuli, and more can be seen during the Manaslu Circuit Trek in September. Wil animals like the blue ship, marmot, deer, and many others during the trekking offer a different experience from the Manaslu trek in September. In this post, let’s check why September is one of the best times to trek to the Manaslu circuit.

The temperature might decrease by 7-8 degrees Celsius in the higher region of the Manaslu Region in September.

September is the first month of the autumn season. Autumn is one of the busiest trekking seasons for the Manaslu Circuit Trek. But, it can be some rainy days until mid-September.

Rewards of Manaslu Trek in September

Fewer Trekkers

Manaslu Region is restricted, so trekkers must have three different trekking permits and hire a guide. There are fewer trekkers compared to the other commercial trekking routes. September is the beginning of autumn, so there are 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 that you can see mesmerizing views of the high mountains, green hills, and more this month. You can always see beautiful mountains 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 in 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.

Accessible to Cross Larke La

There won’t be snowfall and ice on the Larke Pass in September so the trail will be clear. Crossing this high pass without any difficulties this month will be easy. Also, it won’t be freezing on the pass in September.

Festival Celebration

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 a different memorable experience for you.

Manaslu Trek Preparation in September

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

You must be physically and mentally prepared to trek in a highly elevated region. Mental preparation means reading 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 must be mentally prepared before planning to trek on this route. You better need to discover the difficulties you will face on the trek and be ready to tackle them.

Intense mind makeup provides you more confidence to short out every challenge on the trek. Self encourages, and a concerned mind supports the successful trip by leaving all the doubt far behind, so I think I can do it.

Physical Preparation

Besides Mental Preparation, Physical Preparation is a vital part of the trek to the Manaslu Circuit in September. 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 keep you physically fit for this adventure trek.

Manaslu Trek Difficulties in September

Larke pass (5,106m)

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 extended for a few days in lower areas. There are lots of up and down hills trails so that it can make a tiring walk. You need to cross several streams on temporary wooden bridges at other times. They might not be 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 significantly because of the many 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 from the long camps and altitude effects during the trek. You walk 7-8 hours daily in the lower regions, so long camps with many up and down hills make you Tired. Besides the long trekking days, altitude can also cause Tiredness on the trek.

Difficulty of Accommodation

You will get Accommodation quickly in most places, but in places like Deng, Namrung, Lo Gaun, Samdo, and Darmasala might be challenging 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 sometimes be slippery during the September Manaslu trek. Although, it should not be slippery on the whole trip except for some spots. There will be less rain in the higher areas compared to the lower areas.

Safety and a successful trip are the primal motos of every traveler. Here, I have tried to provide some helpful tips for the Manaslu trek in September.
