October is the best month for the Annapurna Circuit — post-monsoon skies, a reliably open Thorong La Pass, and stable trail conditions from Besisahar to Ghorepani. Here's what to expect section by section, plus how October compares to November for a 2026/27 departure.
The Annapurna Circuit trek in October offers the best overall mountain experience of any season in 2026/27. Not the most convenient in terms of teahouse competition above Manang, but the best in terms of what the circuit actually delivers: post-monsoon skies that scrub the Himalayan panorama clean, a reliably open Thorong La Pass, and the full sweep of the circuit from subtropical Marsyangdi Valley to the high desert above Muktinath under stable conditions on most days.
This guide covers exactly what the Annapurna Circuit trek in October looks like on the ground — section by section, including specific temperatures, crowd levels, and the Thorong La crossing conditions trekkers should prepare for in 2026/27.
The Himalayan monsoon ends in late September. What it leaves behind is an atmosphere scrubbed of dust and haze by months of rain. In October, Dhaulagiri (8,167m), Annapurna I (8,091m), Annapurna II (7,937m), Machhapuchhre (6,993m), and the full panorama visible from the upper circuit appear with a clarity not available in any other season.
Trail conditions match. Paths are dry, rivers are at post-monsoon levels, and the high sections above Manang are clear of the snow that becomes a factor from late November onwards. Thorong La at 5,416m in October is at its most accessible — the surface is firm, the trail is clearly visible, and the crossing, while always demanding, is as straightforward as it gets.
The trade-off: October is the busiest month on the Annapurna Circuit. Teahouses at Manang, Thorong Phedi, and Muktinath fill quickly in peak weeks. Trekkers who do not book ahead may find rooms scarce above 3,500m. This is a logistics problem rather than a trail condition issue — a guide with established teahouse relationships handles it without difficulty.
The lower circuit in October is warm and green. Temperatures at the trailhead near Besisahar range from 15 to 25 degrees Celsius during the day. The Marsyangdi River at post-monsoon levels is turquoise and fast-moving through the gorge sections. The terraced fields of the lower Gurung villages are in their post-harvest stage — golden rice fields alongside the trail between Bhulbhule and Ngadi.
Trail conditions are good throughout this section in October. The road that runs alongside the lower circuit generates dust in dry conditions — your guide will route you onto the walking trail rather than road sections where possible.
The upper Manang Valley in October is at its best. The Paungda Danda rock wall above the Marsyangdi between Chame and Upper Pisang is dramatic in clear October light. The upper route from Upper Pisang through Ghyaru and Geru — recommended over the lower valley route — gives panoramic views of Annapurna II, III, IV, Tilicho Peak, and Gangapurna across the full width of the valley in a way that is not available at any other time of year.
Manang at 3,540m in October has daytime temperatures of 5 to 15 degrees Celsius and cold nights of minus 2 to minus 8 degrees. The village is busy in peak October weeks. Book your Manang teahouse through your guide before arriving — this is the key logistics point on the upper circuit in 2026/27. The acclimatisation day in Manang is built into the Trekking Guide Team Adventure 16-day itinerary and is not optional regardless of how you feel on arrival.
The approach to Thorong La is where October conditions matter most. Ledar (4,200m) and Thorong Phedi (4,525m) in October have overnight temperatures of minus 8 to minus 15 degrees Celsius. A sleeping bag rated to at least minus 10 degrees Celsius is essential. Teahouses at Thorong Phedi in peak October are at capacity — your guide confirms reservations the morning of the Ledar to Phedi section.
The Thorong La crossing in October typically takes place on dry trail with clear visibility. Departures before 4am are standard to beat afternoon winds. On a good October morning, the crossing is demanding but clear — the trail across the pass is well-defined, the surface is firm, and views from the summit at 5,416m extend across the full Annapurna and Mustang landscape.
October summit temperatures at Thorong La: minus 5 to minus 15 degrees Celsius in the early morning depending on wind. Full cold-weather layering is required even on good crossing days — the combination of altitude and pre-dawn wind chill at the summit makes this one of the coldest points on the trek regardless of the season.
The descent from Muktinath (3,800m) into the Kali Gandaki gorge is one of the most visually distinct sections of the circuit and one of the best in October. The arid, flat-light landscape of the upper Mustang region contrasts sharply with everything above it — ochre cliffs, adobe villages, apple orchards in harvest season. October is apple harvest season in Marpha — cider, apple brandy, and fresh apple pie are available and worth stopping for.
Tatopani's natural hot springs in October are one of the best post-high-altitude rewards on any Nepal circuit. The pools are warm, the surrounding valley is green after the monsoon, and a long soak after nine days above 3,500m is genuinely restorative.
The final section through Ghorepani and Poon Hill in October is consistently excellent. The rhododendron forest between Shikha and Ghorepani is mature and dense. The trees are not in bloom in October (bloom season is March and April) but the forest is at its greenest after the monsoon and the trail through it has a cool, quiet quality in contrast to the dry upper circuit.
Poon Hill sunrise in October: consistently one of the best mountain panoramas in the Himalayas. The full Annapurna range and Dhaulagiri in first light, with Machhapuchhre catching the alpenglow. Mountain visibility in October is at its annual peak. Arrive at Ghorepani the evening before and plan for a 4:30am start.
Down jacket: Essential from Manang onwards and critical for Thorong La. Cold nights above 3,500m in October require more than a fleece mid-layer.
Sleeping bag rated to minus 10 degrees Celsius minimum: Teahouse blankets at Thorong Phedi are thin. This is non-negotiable at 4,525m in October.
Sun protection: October UV at altitude is intense. SPF 50+ sunscreen, UV-rated sunglasses, and a sun hat for the lower and mid-circuit sections below 3,000m.
Warm hat and gloves: Required from Manang onwards. For Thorong La, bring liner gloves and waterproof outer mitts — pre-dawn summit temperatures can reach minus 15 degrees with wind chill.
Trekking poles: Strongly recommended. The descent from Thorong La to Muktinath drops 1,600m over 8km — poles protect the knees significantly on the steepest sections.

Is October the best time for the Annapurna Circuit trek in 2026/27?
Yes. October is the single best month for the Annapurna Circuit in 2026/27. Post-monsoon visibility is at its annual peak, Thorong La is reliably open and snow-free, and trail conditions from Besisahar to Ghorepani are at their best. The trade-off is that October is also the busiest month — teahouses at Manang and Thorong Phedi fill quickly and need to be booked in advance. Early November offers the same conditions with slightly thinner crowds and colder nights.
How cold is Thorong La Pass in October?
Pre-dawn summit temperatures on Thorong La in October typically range from minus 5 to minus 15 degrees Celsius depending on wind. Most crossings in 2026/27 begin before 4am when temperatures are at their coldest. A down jacket, warm hat, gloves, and windproof shell are required for all crossing days regardless of how mild the forecast looks from Thorong Phedi the evening before.
How busy is the Annapurna Circuit in October 2026/27?
Very busy above Besisahar in peak October weeks. The Annapurna Circuit is one of Nepal's highest-traffic multi-day treks and October is its peak month. The Manang and Thorong Phedi sections see particularly high trekker density. Trekking Guide Team Adventure books teahouses ahead as part of the guided package — this removes the main practical problem of peak-season crowding.
What permit do I need for the Annapurna Circuit in 2026/27?
The Annapurna Conservation Area Permit (ACAP) is required for all trekkers on the Annapurna Circuit. Fee: NPR 3,390 (approximately USD 25). The permit is included in the Trekking Guide Team Adventure 16-day package and arranged before departure. No other permit is required for the standard Annapurna Circuit route in 2026/27.
