Annapurna Base Camp, also known as Annapurna sanctuary, is one of the most sought trek in Nepal which is known for unique Gurung culture, Himalayan vistas and diverse flora and fauna. There are very few treks in Nepal that takes you so close to the base camp of 8000 meter plus peak in such short time period like Annapurna Base Camp Trek. It takes 7 to 14 days to complete the ABC trek depending on the route and walking hour per day.
The best time to trek Nepal are during two season: in autumn (September – November) and spring (March – May). Both of the season are recommended as the best trekking season in Nepal as you can get the most out of your adventure in terms of scenic views, avoid heavy rainfall, warm days and best weather.
Below is the seasonal guideline to Annapurna Base Camp Trek
October – November
October – November is the most peak season to trek Nepal. It is the time after monsoon season when everything is refreshed, washed clean and vibrant. The weather is warm, even above 3,00m and view of mountains are usually stunning and clear. The temperature goes down below freezing level but the night skies is still filled with a billion stars. Because of its popularity, it is the busiest time in Annapurna route, so better to teahouse in advance.
December – February
This is great time for those who are content with cold weather in the Himalayas. The day time temperature is cool and the temperature will get below zero depending on the altitude. At over 5,000, Thorong La Pass is often covered with snow and will close for days on end when this happens. We suggest you to go for Ghorepani Poon Hill Trek with Annapurna Base Camp Trek in winter, if you are okay with cold weather.
March – May
(March – May) is the second most popular trekking season in the Annapurna region. By April, the snow and cloud dissipated, leaving the views crystal clear. A strange fog appears over the ring of the peaks during May, however as you reach high altitude, the view becomes crystal clear.
July – September

Trekking in Monsoon is far less crowded, so it is best for those who wants to enjoy some lone time with nature. Upper Mustang Trek is best monsoon treks in Annapurna region.
