September is the magical transition month in Nepal, the vital bridge between the wet, humid monsoon season and the crisp, clear early autumn trekking season. If you are planning a September Manaslu Trek, you are choosing a time when the Himalayas are washing off the dust of summer and preparing for the peak trekking rush.
During this journey, you will circle the majestic Mount Manaslu (8,163m), navigate the stunning Budhi Gandaki River gorge, and experience the pristine, uncrowded nature of the 177 km trail. A post-monsoon trek offers vibrant, rain-washed landscapes, lush green forests, and unparalleled clarity for mountain views. However, because this is a transitional month, timing (early vs. late September) is absolutely everything. If you are still deciding on your exact dates, comparing this month with others in our guide to the Best Time for Manaslu Circuit Trek can help you make the final call.
Overview of the Manaslu Circuit Trek in September
Here is a quick snapshot of what to expect on this epic high-altitude route during the early autumn season:
- Total Distance: Approx. 177 km (110 miles).
- Max Altitude: 5,106m (Larkya La Pass / Larke La Pass).
- Trek Duration: Typically 13 to 18 days depending on acclimatization.
- Best Time within September: Mid to late September for the clearest mountain views and driest trails.
- Permits Required: Restricted Area Permit (RAP), MCAP, ACAP.
- Accommodation: Teahouses (fully reopening and freshly stocked after the summer break).
Is September a Good Time for the Manaslu Circuit Trek?
Absolutely, but the experience changes drastically depending on when you arrive. Trekking in Nepal in September requires understanding the shifting weather patterns.
Early September vs. Late September
Early September (Sept 1 – Sept 15): This period represents the tail-end of the monsoon. You should expect frequent afternoon showers, highly humid conditions in the lower Budhi Gandaki gorge, and muddy trails. However, the landscape is at its most spectacular, waterfalls are massive, and the alpine flora is incredibly vibrant and green.
Late September (Sept 16 – Sept 30): This is the sweet spot for an early autumn trek. The rains stop, the skies clear up to reveal stunning, razor-sharp views of Mt. Manaslu, Himalchuli, and Ngadi Chuli, and the trails begin to dry. Best of all, the massive October crowds haven’t arrived yet, leaving the trail feeling peaceful and exclusive.
Pros and Cons of a September Trek
Pros:
- Lush, vibrant landscapes and roaring waterfalls.
- Dust-free trails and incredibly clean alpine air.
- Warmer daytime temperatures compared to late autumn.
- Easy to find teahouse beds without the intense competition of October.
Cons:
- Unpredictable road transport and potential delays due to landslides in the first week.
- Muddy, slippery lower trails and leeches if trekking in early September.
Weather and Temperature on the Manaslu Circuit in September
Understanding the temperature shifts is crucial for packing the right layers. The climate varies drastically depending on your elevation.
Lower Elevations (Soti Khola to Namrung: 800m to 2,600m): The climate here is warm and humid, especially in the first half of the month. Daytime temperatures average a comfortable 18°C–25°C (64°F–77°F).
Mid Elevations (Lho to Samdo: 2,600m to 3,800m): Daytime hiking is highly pleasant, ranging from 12°C–16°C. However, once the sun dips behind the massive peaks, the temperature drops sharply to crisp nights of 2°C–6°C.
What is the temperature at Larkya La Pass in September?
At 5,106m, Larkya La Pass in September experiences daytime temperatures of 2°C to 5°C, but drops to -5°C to -10°C at night and early morning. Fortunately, the pass is generally free of deep winter snowstorms during this month, making the crossing relatively safe and highly rewarding.
Trail Conditions, Difficulty & Safety in September
If you are trekking in early September, you must be prepared for slippery descents and potential trail detours due to swollen rivers. Minor ankle sprains are more common on these muddy post-monsoon trails, so trekking poles are highly recommended. By late September, the trails dry out significantly, making the footing much more stable.
As you approach high-altitude stops like Samagaon and Dharmasala, the risk of Altitude Mountain Sickness (AMS) increases. The key to avoiding AMS is a slow, steady ascent and aggressive hydration. Furthermore, due to the remote nature of the region, carrying comprehensive travel insurance that covers emergency helicopter evacuation up to 6,000m is strictly mandatory.
Because the Manaslu Circuit Trek difficulty is considered moderate to challenging, requiring good cardiovascular fitness, reviewing our guide on How to Prepare for the Manaslu Circuit Trek will ensure you are physically ready for the long days and steep ascents.
Getting There: Road Conditions in September
The drive from Kathmandu to the trailhead at Machha Khola takes approximately 8-10 hours. While the highway from Kathmandu to Arughat is now mostly paved, the final rugged dirt section to Machha Khola remains highly susceptible to monsoon landslides. Therefore, a private 4WD Jeep is highly recommended over local public buses for safety and comfort in early September.
Modern Trailhead Update: Today, the jeep road reliably goes all the way to Machha Khola (and sometimes even further to Salleri), meaning you can skip the lower, warmer sections if you prefer to start at a higher elevation. Additionally, unlike in the past, Ncell and NTC 4G networks now reach up to Samagaun and Samdo, and basic paid Wi-Fi is available in most teahouses up to those villages, allowing you to stay connected during the first half of the trek.
Itinerary Options for the September Trek
The Manaslu Circuit Trek Itinerary remains highly flexible to suit your fitness and schedule. Strong, experienced hikers can complete the circuit in a brisk 13 days. However, those wanting to safely acclimatize or explore spectacular side trails such as the Tibetan border/Rui La, Pungyen Gompa, or the culturally rich Tsum Valley Trek might prefer a more relaxed 16-day route.
The local experts at Himalaya Hub offer customized itineraries tailored exactly to your schedule, ensuring the safest and most enjoyable pace for your specific fitness level.
Essential Packing List for a September Trek
When compiling your Manaslu Circuit Trek Packing List, the focus for September must shift heavily toward rain and mud management.
You must pack waterproof trekking boots, leech socks or gaiters (essential for the muddy lower elevations), and dry bags to protect your electronics. Heavy winter micro-spikes are rarely needed in September, but a waterproof duffel bag is an absolute must for your porters.

Himalaya Hub Guide Tip: “Skip the heavy winter down jacket if you are trekking in early September; instead, prioritize a high-quality Gore-Tex rain shell and waterproof backpack covers. Also, pack a small ziplock of table salt. It’s the best trick for harmlessly removing leeches in the lower jungle sections!”
Accommodation and Food in September
Unlike October, where trekkers often have to fight for a bed, September offers the luxury of choice. Teahouses are freshly cleaned, well-stocked, and welcoming after the quiet summer months. Understanding the overall Manaslu Circuit Trek Accommodation standards will help you appreciate the cozy, rustic comfort of these mountain lodges.
2026 Festival Note: Depending on the lunar calendar, major Nepali festivals like Dashain or Tihar sometimes fall in late September. During these specific days, some local teahouse owners may close for 24-48 hours to celebrate with their families. It is always a smart backup to carry a few extra energy bars or snacks just in case.
To combat the chill and fuel your body, rely on warming, calorie-dense foods. The famous local Dal Bhat is a staple, while hot garlic soup is excellent for altitude acclimatization. You will also notice a unique abundance of fresh, post-monsoon green vegetables in the lower elevations, a rare treat on high-altitude trails. To discover what else to eat on the trail, read our guide on Foods on Manaslu Circuit Trek.
Permits, Regulations, and Cost in September
To trek in this restricted region, you need three specific permits: the Restricted Area Permit (RAP), the Manaslu Conservation Area Project (MCAP) permit, and the Annapurna Conservation Area Project (ACAP) permit. Note that a TIMS card is not required for the Manaslu region. Navigating the bureaucracy can be tricky, so reviewing our checklist for Manaslu Circuit Trek Permits will ensure you have all the necessary paperwork in order.
Because September marks the beginning of the autumn pricing tier, the RAP costs $100 for the first week. The MCAP and ACAP permits cost 3,000 NPR (approximately $23–$25 USD) each. For a full breakdown of the paperwork and budgeting, read our detailed guide on the total Manaslu Circuit Trek Cost.
Why Choose Manaslu Over Annapurna in September?
When deciding between the two classic circuits, Manaslu holds a distinct advantage in September. Annapurna’s newer road infrastructure gets incredibly muddy and is highly prone to landslide blockages during the tail-end of the monsoon. Manaslu, however, remains a wild, foot-traffic-only path. This means you get a much more authentic, uninterrupted adventure without the risk of getting stuck behind a landslide-blocked jeep track.
Conclusion
Trekking the Manaslu Circuit in September offers a beautiful, early autumn experience. You will be rewarded with the perfect balance of lush green valleys, roaring waterfalls, returning clear mountain views, and quiet, peaceful trails.

We went to Nagarkot, did a safari in Chitwan, and went rafting by the Trishuli riverside. We also did a 5-day trek to Poon Hill and stopped at Jhinu for the hot springs. (It just take 3days to go to Poon hill, the remaining days is just chilling)
Our guide Shubash Bhattarai is a solid 10/10. He is super friendly and really knowledgeable. He shared a lot about the local culture, mountains, and wildlife along the way. If we come back to Nepal, we’ll definitely look for him again for our next trek.
He really made the whole experience even better. What started as having a guide ended up feeling like making a genuine friendship. His knowledge, kindness, and positive energy made every day enjoyable and stress-free.
I’ll definitely be back for another trek in Nepal, and I very much hope to have Ramit as my guide again. Highly recommend!
