The Best Time for Everest Three Passes Trek is one of Nepal’s most ambitious and rewarding high-altitude trekking adventures, taking hikers across three challenging mountain passes—Kongma La (5,535m), Cho La (5,420m), and Renjo La (5,360m)—while also offering views of Mount Everest, Gokyo Lakes, and numerous Himalayan giants. However, due to the demanding terrain and extreme altitudes, timing is everything. Choosing the right season can significantly affect your safety, comfort, and overall experience.
This guide explores the best time to undertake the Everest Three Passes Trek, examining each of Nepal’s trekking seasons, along with insights into weather patterns, trail conditions, and crowd levels.
Ideal Seasons for the Everest Three Passes Trek
There are two optimal seasons for this trek:
1. Spring (March to May)
Spring is one of the best and most popular times to trek in the Everest region. The weather is relatively stable, and the days grow warmer as the season progresses.
Advantages:
- Clear skies and stable weather: This is a great time for mountain photography. Views of Everest, Lhotse, Nuptse, and Ama Dablam are often crystal-clear.
- Comfortable temperatures: Days are moderately warm, especially in lower elevations. Although nights above 4,000m can still be cold, it’s more bearable than winter.
- Blooming rhododendrons and wildflowers: Lower altitudes around Namche Bazaar and Tengboche are especially scenic in April.
- Well-marked trails and open lodges: Most tea houses are open, and the trails are in good condition after the dry winter.
Considerations:
- As May approaches, humidity and haze can increase, especially in lower regions.
- It’s a busy season, so expect more trekkers on the trail and in teahouses, particularly around Everest Base Camp.
2. Autumn (Late September to November)
Autumn is widely regarded as the Best Time for Everest Three Passes Trek particularly October.
Advantages:
- Exceptional visibility: Skies are consistently clear after the monsoon has cleared out dust and pollution.
- Ideal temperatures: Like spring, daytime temperatures are moderate, and nights are cold but manageable.
- Dry trails: Rain is minimal, and river crossings are easier due to lower water levels.
- Festive atmosphere: Autumn coincides with Nepal’s biggest festivals, Dashain and Tihar, offering trekkers a glimpse into local traditions.
Considerations:
- High traffic: This is the busiest trekking season. Booking accommodations in advance is advisable.
- Quick drop in temperatures: Late November can be very cold, particularly on the passes. Be prepared for early snow.
Other Seasons: Should You Trek?
3. Winter (December to February)
While technically possible, trekking during the winter months is only recommended for highly experienced trekkers equipped with proper gear.
Challenges:
- Extreme cold: Temperatures can drop below -20°C at higher elevations. Snowfall can close passes without warning.
- Limited accommodation: Many lodges in higher elevations close for the season.
- Risk of avalanches and blocked trails: Some sections, particularly Cho La and Kongma La, become dangerous and may require crampons or technical skills.
Advantages:
- Unmatched solitude: Very few trekkers attempt the Three Passes in winter.
- Beautiful snow-covered landscapes: For photographers, the scenery can be incredibly dramatic and pristine.
4. Monsoon (June to Mid-September)
This is the least favorable time to do the Everest Three Passes Trek.
Challenges:
- Heavy rainfall and landslides in lower regions.
- Cloudy skies and poor mountain views for most of the day.
- Leeches and slippery trails below 3,000m.
- Flight delays to and from Lukla due to low visibility.
Advantages:
- Fewer trekkers: For those who don’t mind getting wet, the trail is quiet.
- Lush greenery: Valleys are vibrant and alive after the rains.
