Why Winter (December To February)?: Quiet Trailhead
If you want to see what a winter wonderland looks like, do the Annapurna Sanctuary Trek in winter, as you will be rewarded with snow-covered landscapes all around. During the winter season, trekking offers completely new adventure opportunities and, above all, busy paths become serene and empty. The winter skies deliver exceptional views with snow-covered mountain peaks standing in front of deep blue skies. However, be ready for the cold! Freezing temperatures become common in the upper elevations during nighttime. Be sure to double-check whether higher tea houses will be operating or not, as many tend to be shut for the season. Want to enjoy a peaceful time? Winter is just right for you!
Monsoon Season (June To August)
During the monsoon season, the Annapurna region receives continuous rainfall every day, so only brave trekking enthusiasts choose to explore this period despite most people staying away at this time. The bright side? The mountains undergo a complete transformation to deep green colors while multiple waterfalls emerge across the landscape and flowers bloom along the trails, and the forests feel alive and fresh. You will experience total solitude on the trails because no other groups are present. However, be prepared for challenges. The lower sections of the forests attract leeches, while slopes become uncomfortably muddy with slippery surfaces. The mountain vistas become obscured by cloud cover, but sometimes clear morning conditions can offer beautiful views. Safety risks on the trail mostly come from landslides and flooding that affect specific trail sections in lower regions.

Tips for Choosing the Best Seasons for the Annapurna Base Camp Trek
- The selection of trekking season should depend on your personal preference for weather. People who dislike rain and snow should stay away from monsoons and winters. People commonly prefer the moderate climate found during spring and autumn months.
- The trek presents diverse views depending on when you visit therefore consider which sights you most desire. Springtime provides the opportunity to see the vibrant rhododendrons and during autumn, you can enjoy the perfect mountain vistas.
- During spring and autumn, the trails have the most visitors since trekking paths become filled with numerous hikers while teahouses frequently reach capacity. The trails remain peaceful in both winter and monsoon seasons.
- Select the season based on your physical fitness level. Autumn and spring provide the simplest trekking experience because trails are dry with favorable weather. Trekking during the monsoon and winter months presents the highest level of difficulty.
- If you want to experience the local festivals and culture, October and November are the times for the Dashain and Tihar festivals so you can enjoy local celebrations in mountain villages.
- If photography is essential to you, then plan your activities based on photography targets. October and November bring the most transparent mountain vistas since skies remain completely unclouded. Wildlife photography and flower shots become more achievable during the spring season.
- Plan your expenses according to the changing seasonal costs. You will find that the highest accommodation and guide prices are during peak seasons. The off-season periods provide discounts that range from 10% to 30%.
- Plan about essential gear requirements based on seasonal changes. Spring and fall seasons provide the best options since they require minimal specialized equipment.
- Consider your schedule flexibility. Teahouses during the perfect weather season (October-November) need early reservations since they quickly become fully booked. You can choose to trek during the monsoon and winter seasons without booking in advance.
- During monsoon, the Annapurna region experiences low rainfall levels in certain sections which exist under a rain shadow area. Researching the microclimatic conditions of your selected route enables you to select the optimal route.
Is winter safe for the ABC Trek?
The big question remains: Is it safe to trek in winter? Yes! You can experience safe winter trekking to Annapurna Base Camp through proper preparation. Freezing temperatures combined with snowfall and slippery terrain pose the main difficulties on the journey. A successful winter trek to Annapurna Base Camp requires layered warm clothing along with an elite sleeping bag and optional microspikes on your boots.
The season remains safe overall but presents additional risks for the trekker. The sun sets quickly! Remember to start the day early so you reach your next stop before it gets dark. High passes during winter may contain thick layers of snow so you need to be extra careful. One step at a time! Main trail tea houses continue operations yet those located in remote areas could shut down for the season. Before the trek begins, you should check the weather forecast or the best option is to get an experienced guide who masters winter trekking.
How challenging is the monsoon season?
By now, you may have known that the monsoon season is not a piece of cake, as the Annapurna Base Camp Trekking in Nepal faces major difficulties. The main obstacle? Frequent rainfall continues throughout the day, covering the trails with mud while also becoming dangerously slippery. The rainy weather produces deep flowing water that rushes through small streams and some parts may experience severe flooding and even landslides, blocking the path.
And how can we forget the annoying leeches! They are everywhere in the forest area, clinging to your skin. The worst of all? The mountain views are regularly covered by clouds and fog while the high humidity makes you sweat a lot, like a lot!.
But don't be hopeless! Although these conditions might appear challenging, anyone can embark on an Annapurna Base Camp trek during monsoon using proper gear alongside an optimistic mindset.
How does altitude affect trekkers during different seasons?
The journey to the high Himalayas is not easy and you know what makes it harder? The altitude. The Annapurna Base Camp Trek extends to 4,130 meters where altitude creates varying effects depending on the season for the trekkers. High altitude combined with cold winter conditions makes it harder to breathe because air at this temperature contains less oxygen. Your body needs to generate more heat to maintain body temperature and process limited oxygen availability. And if you fail to adapt to high altitude, altitude sickness is a high risk.
When ascending to higher elevations during monsoon season, you will encounter thinner and cooler air which provides relief for some trekkers but the view from steep ascents to the top is blocked by fogs and clouds, which can be a disappointment. Autumn and spring represent the optimal time when you can adjust your bodies to altitude changes due to mild temperatures. To handle altitude during your trek, you need to drink lots of water while moving at a slow pace with a limited daily elevational gain of 500 meters and practicing periods of rest in your Annapurna Base Camp Trek itinerary. If you are a fast-paced walker, then you should opt for the Annapurna Base Camp Short Trek.
Conclusion: Final Say
Perhaps now you know what the best time to embark on the trek to Annapurna Base Camp is. Your decision on when to do this trek will directly affect what sights and experiences you want to encounter. The season of spring features beautiful flowers, while autumn presents clear mountain vistas and winter brings peace on trails, and monsoon paints the land in dark green.
