Manaslu: The Trekker's Trek

Hidden behind the curtain of mainstream routes like Everest and Annapurna, the Manaslu Circuit Trek remains one of Nepal's best-kept secrets a raw, untamed journey around the world’s eighth-highest mountain. It’s not for everyone, and that’s exactly why it’s so loved. Fewer crowds, richer culture, wilder trails but to truly experience its magic, timing is everything.

This guide is your definitive answer to one critical question: When is the best time to trek the Manaslu Circuit? Whether you're a first-time Himalayan explorer or a seasoned mountain nomad, this resource is built to help you find your perfect trekking season with honest, expert-backed advice.

The Best Time to Trek the Manaslu Circuit

• Best Overall Trekking Season: Autumn (September to November)

If you're seeking the most reliable weather, crystal-clear views of Mount Manaslu (8,163m), and the cultural richness of local harvest festivals, autumn is the best time to trek the Manaslu Circuit. Post-monsoon skies are brilliantly clear, with moderate daytime temperatures and minimal precipitation — ideal for crossing Larkya La Pass. This is the peak season for good reason.

• Second Best Time for Manaslu Circuit: Spring (March to May)

Spring transforms the Manaslu region into a floral paradise. Rhododendrons bloom in full color from Philim to Samagaun, wildlife emerges in the forested zones, and high-altitude conditions become increasingly favorable from late April onward. While morning views are often clear, some haze may develop in the lower elevations. Still, it's a fantastic season for both nature lovers and altitude adventurers.

The Four Seasons of Manaslu: A Detailed Breakdown

Autumn (September–November)

Temperatures:

• Lower Elevations: 10–22°C (50–71°F)
• Higher Elevations: -6 to 10°C (21–50°F)

Overview: This is the peak trekking season on the Manaslu Circuit, offering unrivaled mountain views and the most stable weather of the year. Post-monsoon skies are crystal clear, with vibrant harvest activities in villages. Festivals like Dashain and Tihar enrich the cultural experience.

Pro Tip: Book permits and lodges early; trails are busiest during mid-October.

Spring (March-May)

Temperatures:

• Lower Elevations: 12–25°C (54–77°F)
• Higher Elevations: -4 to 12°C (25–54°F)

Overview: Spring paints the trail with blooming rhododendrons, especially from Philim to Shyala. Melting snow improves access to Larkya La Pass by mid-April. Days are longer and warmer, perfect for nature photography and forest exploration.

Pro Tip: Begin your trek by early April to catch peak flower bloom and avoid increasing haze.

Winter (December–February)

• Lower Elevations: 4–15°C (39–59°F)
• • Higher Elevations: -15 to -5°C (5–23°F)

Overview: Winter trekking in Manaslu is quiet and dramatic. Snow blankets the higher regions, and the Larkya La Pass is often impassable. Fewer teahouses are open, and you must be prepared for subzero conditions and shorter daylight hours.

Pro Tip: Stick to lower-altitude destinations like Tsum Valley or Samagaun if snow blocks the upper route.

 Monsoon (June–August)

Temperatures:

• Lower Elevations: 18–30°C (64–86°F)
• Higher Elevations: 5–15°C (41–59°F)

Overview: The monsoon season brings heavy rain, slippery trails, leeches, and landslide risks, especially below 2,000m. However, the lush, emerald landscapes are incredibly photogenic, and the forest feels otherworldly in mist.

Pro Tip: Only consider this season if you're trekking with a local guide and real-time weather updates. Strong waterproof gear is essential.

How is Climate Change Impacting the Manaslu Circuit Trek?

Our guide, Nam Raj, with over 15 years of experience on the Manaslu Circuit, says, “We see it every year now. The monsoon sometimes lasts into the first week of October, bringing unexpected rain. And sometimes, we get a big, surprise snowfall on the pass in late November. The old rules are not as strict anymore.”

Climate change is reshaping the trekking calendar in the Himalayas, making weather patterns increasingly unpredictable. Here's how it's affecting your Manaslu trek planning:

• Blurring Shoulder Months: Late September often still feels like a monsoon, and late May can see early rains. Seasonal transitions are less clearly defined.
• Lingering Monsoon Tail: Rainfall frequently extends into early October, delaying the arrival of the crystal-clear skies that define peak season.
• Unpredictable Snowfall: Larkya La Pass now experiences erratic snowfall — some years bring unexpected blizzards even in summer, while other years see no snowfall at all during winter.
• Shrinking Glacial Lakes: Rising temperatures are drying up high-altitude lakes like Ponkar and Birendra. Some seasons, they hold barely any water — a clear sign of climate stress.

Smart Trekking Tips in the Age of Climate Change:

• Add Buffer Days: Always plan 1–2 extra days for potential weather delays, especially near Larkya La.
• Research Historical Weather Data: Use monthly temperature and precipitation records to better understand what to expect.
• Pack for Two Seasons: Even in spring, snowstorms can surprise you. Autumn nights can also dip well below freezing.
• Check Trail Updates Locally: Places Nepal Treks’ guides are on the ground and offer real-time insights on snow levels, teahouse availability, and weather shifts.
• Be Flexible: Season windows are changing — adapt your mindset and itinerary accordingly.
