Quick Overview:
- Best months: October, November (autumn) and March, April (spring)
- Annapurna Circuit in Nepal distance: Approximately 160 to 230 km (100 to 145 miles)
- Duration: 10 to 21 days depending on route and pace
- Highest point: Thorong La Pass at 5,416 metres
- Starting point: Besisahar (760m), Gandaki Province, Nepal
Imagine stepping off a winding mountain road in central Nepal and beginning a journey that takes you from subtropical forests thick with rhododendrons all the way to a stark high-altitude desert that feels closer to the moon than the valley below. That is the best time for Annapurna Circuit trekking in a single image: a journey of such extraordinary diversity that the right season transforms a great trek into a defining life experience.
The Annapurna Circuit in Nepal is widely regarded as one of the great long-distance treks on earth. It circles the entire Annapurna massif, crossing the legendary Thorong La Pass at 5,416 metres, passing through Gurung, Tibetan, and Thakali villages, and offering front-row views of Annapurna I (8,091m), Manaslu (8,163m), and Dhaulagiri (8,167m) along the way. Lonely Planet has consistently ranked it among the world’s finest trekking routes, and every year thousands of trekkers from the USA, UK, Australia, and Europe set out to walk its length.
But choosing the wrong month can mean frozen passes, washed-out trails, or trails so crowded that teahouses run out of beds. Choosing the right month, on the other hand, rewards you with crisp mountain air, cloudless skies at sunrise, and trails that feel perfectly alive with fellow trekkers and the rhythms of high-altitude village life.
This complete guide covers every season, the full Annapurna circuit in Nepal distance breakdown, what to expect at each elevation, permits, costs, and month-by-month advice so you can plan your Circuit with total confidence.
What Is the Annapurna Circuit in Nepal and Why Does Season Matter So Much?
The Annapurna Circuit in Nepal is not a single fixed trail but a loop of approximately 160 to 230 km (100 to 145 miles) around the Annapurna Massif in Gandaki Province. The exact Annapurna circuit in Nepal distance you walk depends on which starting and finishing points you choose, whether you add side trips such as Tilicho Lake or the Muktinath extension, and how much of the lower route you cover by jeep or bus rather than on foot.
The traditional circuit begins in Besisahar at 760 metres and climbs steadily northeast through the Marshyangdi River valley, crossing the Thorong La Pass into Mustang before descending to Muktinath and ultimately finishing in Jomsom or Nayapul near Pokhara. The route crosses multiple climate zones, from subtropical lowlands to alpine desert, and passes through several distinct cultural regions where Gurung, Tibetan Buddhist, and Hindu Thakali communities have lived for centuries alongside the trekking trade.
Season matters to the Annapurna Circuit in Nepal more than almost any other major trek in Nepal. The trail’s altitude range is extreme: you begin near the elevation of Kathmandu and end at the world’s deepest river gorge, but in between you cross a pass that rivals the height of some of Nepal’s trekking peaks. Thorong La Pass sits at 5,416 metres, and its conditions vary dramatically across the year. In October and November, it is firm and dry. In winter, it can be closed entirely for days at a time under heavy snowfall. In the monsoon, the lower valleys turn to mud while the upper valley remains surprisingly dry.
Understanding this range is the key to choosing your window. The Annapurna Circuit rewards patience and timing.
What Does the Annapurna Circuit Map Look Like?
The classic Annapurna Circuit map traces a counterclockwise loop that begins in Besisahar and ends in Nayapul or Jomsom. The route divides naturally into three stages. The lower eastern section follows the Marsyangdi River through Chame (2,670m) and Pisang (3,300m) into the Manang Valley (3,519m). The central high section climbs from Manang through Letdar (4,200m) and Thorong Phedi (4,450m) to Thorong La Pass (5,416m). The western descent drops into Muktinath (3,800m) and continues south through Jomsom (2,720m) and Marpha before reaching Kagbeni and ultimately the lower trail to Nayapul.
Most trekkers walk the circuit counter-clockwise because this direction involves a gentler ascent profile toward Thorong La from the eastern side and a more manageable single descent day on the western side. Walking clockwise dramatically steepens the western approach to the pass.

Pro Tip: Download the Annapurna circuit map on Maps.me or Gaia GPS before leaving Pokhara or Kathmandu. Mobile signal is patchy above Chame and largely absent above Manang. A downloaded offline map with trail waypoints can be the difference between a confident crossing and a stressful one.
The Best Time for Annapurna Circuit: A Season-by-Season Breakdown
Choosing the best time for Annapurna Circuit trekking comes down to four distinct windows: spring, monsoon, autumn, and winter. Each has its advantages and trade-offs. Here is what you genuinely need to know about each.
Autumn: October and November (The Prime Season)
Autumn is universally regarded as the best time for Annapurna Circuit trekking, and October is the single finest month of the year on this trail. The summer monsoon ends in late September, clearing the air of haze and leaving the sky a vivid, unfiltered blue. Daytime temperatures at lower elevations sit comfortably between 15°C and 22°C, making the walking days enjoyable rather than exhausting. At Thorong La Pass itself, daytime temperatures in October hover around -5°C to 0°C, cold but entirely manageable with proper layering.
Mountain visibility in October and November is at its annual peak. You will see Annapurna I, Dhaulagiri, and Manaslu from multiple trail sections in conditions that winter haze or summer cloud simply cannot match. Teahouses across the route are open and well-stocked. Trail conditions are firm and dry, and Thorong La Pass is reliably crossable throughout both months.
November brings slightly colder temperatures, particularly at altitude, with Thorong La Pass sitting around -10°C to -15°C at dawn when most summit attempts begin. The trail is less crowded in November than in October, making it a slightly quieter, more personal experience. Lower teahouses may start closing in late November as the season winds down.
The trade-off of autumn is popularity. October and November draw the largest volumes of trekkers to the Annapurna Circuit in Nepal. Teahouses in Manang and Thorong Phedi fill up quickly during peak weeks. Booking accommodation in advance, particularly for the Thorong Phedi camp on the night before the pass crossing, is strongly advised.
Pro Tip: Start the Thorong La crossing no later than 4:00 AM. Strong winds develop on the pass by 10:00 AM and can make the exposed final section genuinely dangerous. Most teahouse owners will wake you with tea and a packed breakfast if you arrange this the night before.
Spring: March, April, and May (The Second Best Season)
Spring is the second-best period and arguably the most visually spectacular for the lower sections of the Annapurna Circuit in Nepal. March and April bring the famous rhododendron blooms: forests of red, pink, and white flowers carpet the hillsides from around 1,800 to 3,500 metres, creating scenery that autumn, for all its clarity, cannot replicate.
Temperatures in spring are warmer than autumn at lower elevations, sitting between 18°C and 26°C in the Marsyangdi valley, which makes the lower trail days very comfortable. At altitude, daytime temperatures above 4,000 metres are similar to autumn, though nights are slightly warmer. Thorong La Pass conditions in March can still carry snow from the winter, with icy sections possible in the early morning. By April, conditions are generally excellent and the pass opens reliably.
May brings warmer, hazier conditions. Pre-monsoon clouds begin building in the afternoon, and visibility at high altitude can deteriorate during the later hours of the day. Temperatures at lower elevations climb into the high 20s, making the initial days of the trek warm and sweaty. Nevertheless, May remains a perfectly viable month for the Circuit, particularly for trekkers who prioritise fewer crowds over peak visibility.
Spring is the busiest season for the overall Nepal trekking industry, with both the Annapurna Circuit and Everest Base Camp trekking routes drawing their largest annual visitor numbers. Plan accommodation in advance, particularly in Manang.
Monsoon Season on the Annapurna Circuit: June to August
The Annapurna Circuit in Nepal during monsoon presents a genuinely different experience from peak season, and not entirely a worse one. This requires careful explanation.
The lower eastern sections of the circuit, particularly from Besisahar through the Marsyangdi valley, receive heavy monsoon rainfall from mid-June through August. Trails become muddy, leeches are common below 2,500 metres, rivers run high and some crossings can be hazardous, and the persistent cloud cover eliminates most of the mountain views that draw trekkers to this route in the first place.
However, the upper western sections, specifically from Manang northward and through the Kali Gandaki gorge, including Muktinath and Jomsom, lie in the rain shadow of the Annapurna and Dhaulagiri massifs. This means they receive significantly less rainfall during the monsoon and remain trekable. The landscape in the upper Mustang valley during June, July, and August is dry, wildflower-covered, and remarkably crowd-free.
For trekkers willing to adapt their itinerary, the monsoon season offers some of the most peaceful, least commercial walking on the entire circuit. You will have teahouses largely to yourself. Prices are sometimes negotiable. The upper valley is hauntingly beautiful in the clear post-rain light. However, this season demands flexibility, experience with variable conditions, and acceptance that the views you came for may sometimes be hidden.
If the Mustang section appeals to you particularly, our Mustang Itinerary: Your Complete 2026 Planning Guide covers the full upper Mustang extension in detail, including the best months for the rain-shadow effect.
Pro Tip: If trekking during monsoon, consider beginning the circuit from Jomsom or Muktinath on the western side and walking east toward Manang. This keeps you in the rain-shadow zone for longer and only brings you into the wetter eastern sections toward the end of your trip.
Winter on the Annapurna Circuit: December to February
Winter on the Annapurna Circuit in Nepal is the season most trekkers are advised to avoid, though this advice deserves nuance. December is often pleasant in the lower sections and carries some of the clearest skies of the year. January and February, however, bring heavy snowfall at altitude, and Thorong La Pass can close entirely for days at a time under one to two metres of fresh snow.
Temperatures at Thorong La in January average -20°C to -30°C at dawn, and the risk of frostbite on an exposed crossing is very real without specialist cold-weather mountaineering gear. Most high-altitude teahouses close between December and February. Trekkers who attempt a winter crossing of Thorong La without current local knowledge, proper equipment, and an experienced guide take a significant risk.
The lower sections of the circuit, however, remain perfectly pleasant in December and even January. Walking from Pokhara through Ghandruk, Ghorepani, and Poon Hill in December delivers some of the finest mountain photography of the year: clear air, snow-dusted peaks, and near-zero crowds. If the full circuit is not your goal, a December lower circuit partial route is a genuinely rewarding option.
Annapurna Circuit in Nepal Distance: What You Actually Walk
The Annapurna Circuit in Nepal distance is one of the most frequently asked questions among first-time trekkers planning this route. The answer depends on your choices, but here is the practical breakdown.
The full traditional circuit covers approximately 160 to 230 km (100 to 145 miles) in total. This breaks down roughly as follows:
- Besisahar to Chame: approximately 47 km over 3 to 4 days
- Chame to Manang: approximately 45 km over 3 days
- Manang to Thorong La Pass summit: approximately 27 km over 2 days
- Thorong La to Muktinath: approximately 8 km (descent)
- Muktinath to Jomsom: approximately 22 km over 1 to 2 days
- Jomsom to Tatopani to Nayapul: approximately 60 to 70 km over 3 to 4 days (or drive from Jomsom)
Daily walking distances typically range from 8 to 17 km (5 to 10.5 miles) per day, with 5 to 8 hours of active trekking. The terrain varies considerably: lower valley sections on well-maintained trails give way to rocky, high-altitude paths above Manang, and the final approach to Thorong La is a steep, oxygen-thin slog that takes 4 to 6 hours from the high camp.
Most trekkers complete the circuit in 12 to 16 days. Faster, experienced trekkers with good acclimatisation can finish in 10 days. A comfortable pace with a Tilicho Lake side trip and rest days at Manang and Jomsom takes 18 to 21 days and is the approach we recommend for first-time Himalayan trekkers.
For those new to multi-day Himalayan trekking, our Everest Base Camp Trekking Guide for Beginners: Complete 2025 Preparation Plan covers the fitness preparation, gear, and altitude management principles that apply equally to the Annapurna Circuit.
Permits, Costs, and Logistics for the Annapurna Circuit
Planning the practical side of your Annapurna Circuit in Nepal trip requires understanding a few key administrative requirements that have changed significantly in recent years.
Permits Required in 2026/27
Two permits are required for the Annapurna Circuit. The Annapurna Conservation Area Permit (ACAP) is the primary and most rigorously enforced document. It costs NPR 3,000 (approximately $22 to $30 USD) for foreign nationals and NPR 1,000 for SAARC nationals. Children under 10 years old do not require a permit. The ACAP is checked at multiple checkpoints from Besisahar onward and at the Jomsom checkpoint on the western side. Trekking without a valid ACAP results in fines and forced removal from the trail.
The TIMS Card (Trekkers’ Information Management System) remains on some official documentation and is still issued by trekking agencies, though enforcement varies across different sources in 2026. The most current advice from reputable agencies is to carry both documents if trekking independently, as checkpoint enforcement policies can change within a season.
Both permits are obtained in person at the Nepal Tourism Board offices in Kathmandu or Pokhara. They are not currently available online. Bring your passport, one passport-size photograph, and the exact fee in Nepali rupees. Trekking agencies handle all permits automatically for clients on organised packages.
Guide Requirements
Since 2023, Nepal’s regulations technically require all foreign trekkers to use a licensed guide. In practice, enforcement on the Annapurna Circuit varies, but booking with a reputable guide adds immeasurable value: route knowledge, cultural context, emergency communication, and logistical support on the most demanding days. Licensed guides typically charge $25 to $35 per day.

Total Trek Budget
A standard Annapurna Circuit package through a reputable registered agency costs approximately $1,200 to $1,800 USD for a 14-day trip, inclusive of guide, porter, accommodation, and most meals. Independent trekkers on a careful budget can complete the circuit for $50 to $80 USD per day covering accommodation, food, and permit. Always purchase comprehensive travel insurance covering helicopter evacuation before you leave, as a rescue from altitude can cost $3,000 to $7,000 without coverage.
Pro Tip: Carry sufficient Nepali rupees from Pokhara or Kathmandu before beginning the trek. ATMs in Besisahar and Chame are unreliable, and above Manang there are no banking facilities at all. Calculate your full trip budget and add a 20% contingency for emergency funds.
Month-by-Month Guide to the Best Time for Annapurna Circuit
Here is a concise, honest assessment of every month for planning your best time for Annapurna Circuit visit:
- January: Lower sections accessible and visually spectacular with snow-dusted peaks. Thorong La often closed by heavy snow. Only for experienced cold-weather trekkers with specialist gear.
- February: Still cold at altitude, but conditions begin improving toward month’s end. Pre-season quiet, good value on accommodation. Thorong La increasingly crossable by late February with local guidance.
- March: Spring officially begins. Rhododendrons start blooming from 1,800 metres upward. Thorong La may have icy sections from winter snow. One of the best months for lower circuit scenery.
- April: Peak spring season. Rhododendron blooms at their most vivid. Thorong La fully open and reliable. Excellent trail conditions throughout. Growing crowds from mid-month onward.
- May: Warmer lower sections, pre-monsoon cloud building in afternoons. Still good conditions at altitude. Less crowded than April. Haze can limit mountain views on lower trail days.
- June: Monsoon arrives. Lower valley trails become wet and leech-prone. Upper Mustang section (above Manang) remains dry. For experienced trekkers only.
- July: Peak monsoon. Lower circuit difficult and muddy. Upper circuit quiet and dry with wildflowers at peak. Specialist season for those who know the route.
- August: Similar to July. Late August sees monsoon beginning to ease. Pre-season quiet for those who arrive early.
- September: Monsoon clearing. Conditions improving rapidly after mid-month. Late September is excellent, essentially early autumn, with minimal crowds and good visibility.
- October: The finest month. Crisp air, cloudless skies, firm trails, Thorong La reliable. Busiest month of the year. Book accommodation well in advance.
- November: Excellent conditions throughout. Slightly fewer crowds than October. Getting colder at altitude by month’s end. High teahouses begin closing after mid-November.
- December: Lower sections beautiful and quiet. Snow risk growing at altitude from mid-month. Many high teahouses closing. Best for partial circuit or lower route alternatives.
Essential Packing List for the Annapurna Circuit
