The Annapurna Base Camp Trek is one of the most popular treks in Nepal. It takes you close to Annapurna I (8,091m) and Machapuchare (6,997m), two of the most striking peaks in the Annapurna range.

The trek usually starts from Nayapul and passes through rhododendron forests and Gurung villages. Some routes begin at Jhino Danda or Ulleri, and if you trek via Poon Hill, you start at Hile or Ulleri instead. Along the way, you get both mountain views and a look at local culture.

The trail ends at Annapurna Base Camp itself, sitting at 4,130 meters. From there, you get close-up views of the Annapurna massif.

As you walk, the trail passes through different climate zones. Lower areas have subtropical forest, while the area near base camp turns into alpine landscape. Villages like Ghorepani and Chomrong have teahouses where you can rest and eat. The trail is well marked and moderately hard, so it works well for beginners who are reasonably fit. Still, you need to acclimatize properly to altitude for a safe trek.

Best Time for Annapurna Base Camp Trek​

The best time for the Annapurna Base Camp Trek is spring (March to May) or autumn (September to November). Both seasons bring clear skies, good mountain views, and dry, safer trails.
During these months, you get clear views of peaks like Annapurna I (8,091m) and Hiunchuli (6,441m). Trails are dry, which makes walking easier and safer. Because these are the busiest trekking seasons, teahouses and lodges are well set up and comfortable for overnight stays.

Weather still changes with season and elevation:

• Spring: Daytime temperatures in lower areas like Chomrong (2,170m) reach 15°C to 20°C. Nights at Base Camp (4,130m) drop to about -5°C.
• Autumn: Days near villages stay cool and crisp, around 12°C to 18°C. Nights at higher altitude fall between -5°C and -10°C, sometimes lower.

Winter and summer (monsoon) see fewer trekkers, but the weather is less predictable. Winter brings snow, and summer brings heavy rain, so trail conditions can turn risky.
Overall, November and April are considered the best individual months for the Annapurna Base Camp Trek, based on weather, trail conditions, and views.

Annapurna Base Camp Trek in Autumn (September, October, and November)​

Autumn is widely seen as the best overall season for the ABC Trek. It runs from September through November. Skies are usually clear and blue, giving good views of Annapurna I (8,091m) and Machapuchare (6,997m).

Trails are dry after the monsoon, which makes walking safer. Village life also picks up again after the rains, so you get a good mix of nature and culture on the trail.

Annapurna Base Camp Trek in September​

September is the start of the autumn season. Early in the month, light showers are still possible, but the weather clears quickly. Because the monsoon has just ended, the landscape is green and full of plants. Waterfalls near Jhinu Danda and Bamboo are also flowing strongly.

Trails can be a little muddy at the start of the month, but they dry out fast. Daytime temperatures in Chhomrong (2,170m) stay around 18°C to 22°C. At night, temperatures near Annapurna Base Camp (4,130m) drop to about 0°C. Mornings feel cold because of mountain winds, but skies usually clear up by mid-September, giving good views of Annapurna South (7,219m) and Hiunchuli (6,441m).

September has fewer trekkers than October, so trails feel quieter. If you like green scenery and a calmer trail, this month is a solid choice.

Annapurna Base Camp Trek in October​

October is often called the best single month for the ABC Trek. Weather stays steady and dry, which is why this month sees the most trekkers. Blue skies give clear views of Annapurna I (8,091m) and Machapuchare (6,997m), and forest trails between Deurali and Machapuchare Base Camp look lush and green.

Temperatures are comfortable for trekking. At Sinuwa (2,360m), daytime highs sit between 15°C and 20°C. At Annapurna Base Camp, days stay near 10°C, with nights dropping to about -5°C. Days are sunny, and nights are cold and clear, good for stargazing.

Because the trails are dry, walking is safer. Food at teahouses tends to be fresh, since the season is busy and lodges restock often. If you want the most reliable weather for the ABC trek, October is a strong pick.

Annapurna Base Camp Trek in November​

November brings colder air but still offers clear skies. With the monsoon long gone, you get sharp, clear views of peaks like Annapurna South (7,219m) and Gangapurna (7,455m). Trails are dry and easy to walk on, and forests around Dobhan and Chhomrong show autumn colors.

Temperatures start dropping. Daytime highs at Ghandruk (1,940m) stay around 12°C to 16°C, but nights at Annapurna Base Camp can fall to -10°C or lower. Days are still warm enough to trek comfortably, but mornings and evenings turn cold, so pack warm layers.

November suits trekkers who enjoy cold, clear weather and don't mind bundling up. Trails are also quieter than October, giving a more peaceful trek with strong mountain views.

Annapurna Base Camp Trek in Spring (March, April, and May)​

Spring is the second-best season for the ABC Trek, covering March, April, and May. As snow melts, trails reopen after winter. Rhododendron forests bloom, especially around Tadapani and Chhomrong, adding color to the trek along with the mountain views.

Temperatures rise through the season. In March, lower villages see daytime temperatures of 10°C to 15°C, while nights at Base Camp stay around 0°C to -5°C. By May, daytime temperatures at Bamboo (2,310m) reach 20°C, though nights at Base Camp remain cold. Skies can turn hazy as humidity rises later in spring, but mornings are usually still clear.

Annapurna Base Camp Trek in March​

March marks the start of spring trekking. Snow on the trail begins to melt, and the route slowly reopens after winter closure. Lower areas like Ghandruk (1,940m) turn green, but higher sections near Deurali and Machapuchare Base Camp (3,700m) may still hold snow, so walk carefully on icy patches. Rhododendron forests near Tadapani and Chhomrong start blooming early in the month.

Daytime temperatures in Chhomrong stay between 10°C and 15°C. At Annapurna Base Camp, nights can drop to -8°C or lower. Skies are usually clear, giving good morning views of Annapurna I (8,091m), Hiunchuli (6,441m), and Machapuchare (6,997m). Wind picks up at higher altitude, so pack warm gear.

March suits trekkers who want quieter trails, fresh snow, and clear skies, without the bigger crowds of April.

Annapurna Base Camp Trek in April​

April is one of the best months for the ABC Trek. Weather stays consistent, and skies are clear. Rhododendron forests near Ghorepani, Tadapani, and Chhomrong are in full bloom, adding color to the mountain views. You can usually see Machapuchare (6,997m) and Annapurna I (8,091m) clearly each morning.

Temperatures are warmer than March. At Bamboo (2,310m), daytime temperatures reach around 18°C. At Annapurna Base Camp, days stay around 8°C, with nights dropping to -5°C. These milder temperatures make the trek more comfortable, though afternoons can get windy at higher elevation.

Trails get busier as April goes on, but early mornings stay peaceful. With most snow melted and teahouses fully open, April offers a good balance of comfort and scenery.

Annapurna Base Camp Trek in May​

May is the last month of the spring trekking season. It's warmer, with longer days. Rhododendrons still bloom at higher points like Dobhan and Deurali. Mornings usually offer clear mountain views, including Annapurna South (7,219m) and Hiunchuli (6,441m), but afternoons often turn hazy.

Temperatures climb higher than April. At Sinuwa (2,360m), daytime highs reach 20°C or more. At Annapurna Base Camp, days reach about 10°C, with nights around -3°C. Humidity rises later in the month, and clouds can cover the peaks by afternoon, so early starts give the best photos.

May suits trekkers who like warm weather and don't mind some cloud cover in the afternoon. Rain has not started yet, so trails stay dry.
