Annapurna Circuit Trek: The Complete Guide (Days, Thorong La Pass & Packing List)

The Annapurna Circuit was, for decades, considered the single best long-distance trek in the Himalayas — and even with road construction cutting into parts of the original route since the 2000s, the core of it still earns that reputation. This is a trek that takes you through six genuinely different ecological and cultural zones in one continuous journey: subtropical lowlands, pine and rhododendron forest, high-altitude Buddhist villages, and finally a stark, high-desert landscape that feels more like Tibet than Nepal. The centerpiece is Thorong La Pass, at 5,416 meters — higher than Everest Base Camp itself, and the defining physical and mental challenge of the entire trek.

This guide covers everything: how many days you need, the Thorong La crossing, difficulty, permits, cost, and a complete packing list for the trail.

How Many Days Do You Need for the Annapurna Circuit?

The Circuit is genuinely flexible, with realistic itineraries ranging from 8 days (heavily using jeep transport on the lower sections) to 18-21 days (a fuller, slower, more traditional loop with side treks). Road construction now allows some lower sections to be covered by vehicle if you prefer, though most trekkers still walk the core Manang-Thorong La-Muktinath section on foot regardless of how they handle the rest of the route.

• 8-12 days — a faster version, often using jeep transport on the lower approach and descent sections, focused on the core high-altitude crossing
• 12-15 days — the most common standard itinerary, balancing pace with proper acclimatization
• 15-21 days — a fuller, slower loop with more villages, side treks, and buffer days, closer to the traditional experience of the trek before road construction

A typical 14-day itinerary looks roughly like this:

Day	Route	Notes
1	Kathmandu → Besisahar → Jagat (drive/jeep)	Start of the trek proper
2	Jagat → Dharapani	Entering deeper valley terrain
3	Dharapani → Chame	Pine forest, first real mountain views
4	Chame → Pisang	Terrain opens up, dramatic rock walls
5	Pisang → Manang	Entering the high, dry Manang valley
6	Acclimatization day in Manang	Mandatory rest day — often includes an HRA altitude lecture
7	Manang → Yak Kharka	Short, slow ascent into the high zone
8	Yak Kharka → Thorong Phedi (or High Camp)	Positioning for the pass crossing
9	Thorong Phedi → Thorong La Pass (5,416m) → Muktinath	The defining day of the trek
10	Muktinath → Jomsom	Descending into the Kali Gandaki valley, Hindu pilgrimage site
11	Jomsom → Pokhara (flight or drive)	Trek effectively ends here
12-14	Pokhara → Kathmandu	Return travel and buffer days

All trekkers hike the circuit counter-clockwise (Besisahar toward Manang, then over Thorong La to Muktinath) — this direction spreads the altitude gain more gradually and makes the pass crossing considerably safer than attempting it in reverse.

Crossing Thorong La Pass: What to Expect

Thorong La, at 5,416 meters, is the highest point of the trek and the moment the whole circuit builds toward. It's a genuinely demanding day:

• Start time: Around 4 AM from High Camp or Thorong Phedi, to cross before winds pick up later in the day
• Climb: 4-5 hours of steady, cold ascent to the pass itself
• At the summit: Roughly an hour at the top, with views across to Dhaulagiri and the wider Annapurna range
• Descent: A brutal roughly 1,600-meter drop down to Muktinath on the other side
• Total day: 10-12 hours of walking

This crossing is not to be taken lightly. In October 2014, a freak snowstorm on Thorong La killed 43 trekkers and guides — the deadliest trekking disaster in Nepal's history. Since then, Nepal's aviation and trekking authorities have put stricter weather-based pass restrictions in place. If your guide says conditions are marginal and turns the group around, that decision should never be argued with.

How Difficult Is the Annapurna Circuit Trek?

The Circuit is rated challenging — meaningfully harder than Annapurna Base Camp, and generally considered harder than Everest Base Camp too, since it involves a longer total distance, more cumulative elevation gain, and a high point (5,416m) above EBC's own summit elevation (5,364m).

• Total distance: Roughly 160-230 km depending on how much of the route you walk versus drive
• Daily walking: Multiple long days, with the Thorong La crossing itself running 10-12 hours
• Altitude: The core risk on this trek. Most serious cases of altitude sickness on the Circuit happen when trekkers skip the acclimatization day in Manang or push too fast from Yak Kharka toward High Camp
• Beginner suitability: Genuinely possible for a physically fit first-time trekker with a few weeks of training and a properly paced itinerary, but this is a bigger undertaking than ABC and requires honest self-assessment of your fitness and cold tolerance

How to prepare:

• Build cardio fitness for weeks, not days, beforehand — this is a longer, more demanding trek than ABC
• Never skip or shorten the Manang acclimatization day, regardless of how good you feel
• Keep your daypack light — around 8-10 kg is a commonly recommended ceiling
• Avoid alcohol and limit caffeine at altitude, both of which worsen dehydration and altitude sickness risk

Best Time to Trek the Annapurna Circuit

• Autumn (mid-October through mid-November): The clear favorite — stable weather, the clearest mountain views, and the safest conditions for the Thorong La crossing
• Spring (March-May): Also good, with warmer temperatures at lower elevations and blooming rhododendrons, though pass conditions can be more variable than autumn
• Winter (December-February): Thorong La becomes unpredictably snowed in during this period — not recommended unless you're an experienced high-altitude trekker with a flexible schedule
• Monsoon (June-August): Avoided by most trekkers — heavy rain on lower sections and higher avalanche/landslide risk

Permits Required

Every foreign trekker needs the same core Annapurna region permits used for Annapurna Base Camp:

1. ACAP (Annapurna Conservation Area Permit) — roughly NPR 3,000 (about $22-25 USD) for foreign nationals, NPR 1,000 for SAARC nationals. This is the permit consistently checked at trail checkpoints.
2. TIMS Card (Trekkers' Information Management System) — roughly NPR 2,000 for independent trekkers, or less through a registered agency. As with ABC, enforcement of TIMS specifically has become inconsistent on Annapurna trails in recent years, though it may still be requested — confirm current status with your operator.

Since 2026, trekking with a licensed guide is mandatory for the Annapurna Circuit — permits and insurance must be arranged through a registered agency, and independent solo trekking is no longer a legal option for foreign trekkers on this route.

Extending into Upper Mustang? If you plan to continue past Muktinath into the restricted Upper Mustang region, you'll need an additional Restricted Area Permit, which costs roughly $500 for 10 days — significantly more than the standard Annapurna permits, and a separate consideration from the core Circuit itself.

• Combined standard permit cost: Roughly NPR 5,000 (about $37-40 USD)
• Where to get them: Nepal Tourism Board offices in Kathmandu or Pokhara, or arranged directly by your trekking agency

How Much Does the Annapurna Circuit Trek Cost?

• Budget independent trek (12-14 days): Roughly $500-700, though note this style is no longer legally available without a guide as of 2026
• Mid-range guided trek: Roughly $900-1,400
• Comfortable trek with guide and porter: Roughly $1,200-1,800

These figures generally cover permits, teahouse accommodation, meals, and guide/porter costs. Budget separately for a Nepal visa, travel insurance (make sure it covers evacuation from 5,500m+, given the Thorong La crossing), tips, and any side trips like Tilicho Lake.

The Complete Packing List

The Circuit crosses more extreme terrain than either Everest Base Camp or Annapurna Base Camp — from warm, humid lowland forest to the genuinely cold, wind-exposed high desert around Thorong La. Pack for both ends of that range, with real emphasis on cold-weather gear for the pass crossing itself.

Clothing (Layering System)

Base layers

• 2-3 moisture-wicking long-sleeved tops
• 1-2 lightweight/short-sleeved tops for the warm lower valley days
• 1-2 thermal base layer sets (top and bottom) — essential for Manang, Yak Kharka, High Camp, and the pass crossing itself

Mid-layer

• 1 fleece or synthetic insulating jacket

Insulation

• 1 heavy down jacket — don't undersize this. Thorong La and the nights around it are genuinely cold, closer to Everest Base Camp conditions than to Annapurna Base Camp

Outer shell

• 1 waterproof, windproof jacket — wind exposure on the pass itself is a serious factor, not just precipitation
• 1 pair of waterproof over-pants

Bottoms

• 2-3 pairs of trekking pants (lightweight for lower sections, warmer/insulated for Manang and above)

Underwear and socks

• 7-10 pairs of moisture-wicking underwear, given the trek's longer duration
• 8-10 pairs of hiking socks, plus thermal sleeping socks
• Feet stay warm and dry longer with proper wool-blend socks, which matters over this many consecutive trekking days

Headwear and accessories

• A warm beanie — non-negotiable for the pass crossing
• A sun hat/cap for lower, sun-exposed sections
• A buff or neck gaiter for wind and dust protection
• Sunglasses with strong UV protection — snow glare on and around Thorong La is intense
• Warm insulated gloves plus a lighter liner pair — cold hands are a common complaint on the pass morning specifically

Footwear

• Trekking boots — well broken-in, ankle-supporting, waterproof. Given the trek's length and the pass crossing's demanding terrain, boot quality and fit matter more here than on either Base Camp trek.
• Camp shoes — lightweight trainers or sandals for evenings
• Gaiters — genuinely useful here, more so than on ABC or EBC, given possible snow near Thorong La depending on season

Sleeping and Gear

• Sleeping bag rated to at least -15°C to -20°C — the cold at Thorong Phedi/High Camp and the pass morning itself demands a genuinely warm bag, closer to EBC-level requirements than ABC
• Trekking poles — valuable for both the long ascent to Thorong La and the steep 1,600m descent to Muktinath afterward
• Daypack — around 30-35 liters with a rain cover
• Duffel bag for porter-carried gear
• Headlamp with spare batteries — essential for the pre-dawn Thorong La start
• Water bottles or hydration bladder, plus purification tablets or a filter (note: water sources become scarcer and pricier the higher you go)
• Basic first-aid kit, including altitude sickness medication (discuss with a doctor beforehand) and blister care
• Hand and toe warmers (optional but popular) — a small, lightweight addition many trekkers appreciate specifically for the Thorong La morning

What You Don't Need

• Technical climbing gear or ropes — Thorong La is a high pass, not a technical climb, and requires no specialized mountaineering equipment
• An overly heavy pack — given the trek's length, keeping your daypack around 8-10 kg makes a real difference over consecutive long days
• Excess spare clothing — layering and limited laundry stops (mostly in lower villages) are still the standard approach, even on a longer trek like this

Gear Buying and Renting Tips

• Kathmandu (Thamel) and Pokhara both have extensive gear shops; as with the other major treks, watch for counterfeit "branded" gear sold cheap
• Given how cold the Thorong La section gets, this is one trek where it's worth prioritizing a genuinely reliable down jacket and sleeping bag over cutting costs, even if renting rather than buying
• Break in boots well ahead of time — with 12+ days of walking, blister issues compound fast if boots aren't already comfortable on day one

Altitude Sickness: What to Know

This is the single biggest safety factor on the Annapurna Circuit, more so than on ABC and arguably comparable to Everest Base Camp given Thorong La's elevation.

• The mandatory Manang acclimatization day exists specifically to reduce risk before the push toward Thorong La — never skip it
• Watch for headache, nausea, dizziness, and fatigue, and report symptoms to your guide immediately rather than pushing through
• Dehydration significantly increases AMS risk — drink consistently throughout the day, not just at meals
• Avoid alcohol and go easy on caffeine at altitude
• If your guide or local authorities restrict or delay a Thorong La crossing due to weather, treat that as final — the 2014 disaster is a sober reminder of what marginal-weather crossings can turn into

Which Itinerary Should You Choose?

• Limited time, still want the pass? An 8-12 day version using jeep transport on lower sections, focused on the Manang-Thorong La-Muktinath core
• Want the classic, balanced experience? The standard 12-15 day itinerary with full acclimatization built in
• Want the fuller, traditional trek? 15-21 days, with more villages, possible side treks (like Tilicho Lake), and extra buffer days
• Want to extend further? Continue from Muktinath into Upper Mustang with the additional restricted area permit, for a genuinely different high-desert Tibetan-plateau-adjacent experience

Frequently Asked Questions About the Annapurna Circuit Trek

Mid-October through mid-November is considered the safest window, with stable weather and the clearest conditions. Spring (March-May) is also viable, though somewhat more variable.

7. How dangerous is the Thorong La Pass crossing?

It requires serious preparation and respect — a 2014 snowstorm killed 43 trekkers and guides on this pass, the deadliest trekking disaster in Nepal's history. Since then, stricter weather-based crossing restrictions have been implemented, which trekkers should never try to override.

8. How much does the Annapurna Circuit trek cost?

Mid-range guided treks typically cost $900-1,400, while more comfortable packages with a dedicated guide and porter run roughly $1,200-1,800, generally covering permits, accommodation, meals, and guiding costs.

9. What sleeping bag rating do I need for the Annapurna Circuit?

At least -15°C to -20°C, given how cold conditions get at Thorong Phedi, High Camp, and the pass crossing itself — closer to Everest Base Camp-level cold-weather gear than Annapurna Base Camp.

10. Can the Annapurna Circuit be combined with Upper Mustang?

Yes, by continuing past Muktinath into the restricted Upper Mustang region, though this requires an additional Restricted Area Permit costing roughly $500 for 10 days, separate from the standard Annapurna permits.

The Bottom Line

The Annapurna Circuit remains one of the most complete trekking experiences in the Himalayas — six distinct landscapes, deep Buddhist and Hindu cultural sites, and a genuinely earned crossing at Thorong La that ranks among the highest trekking passes most people will ever attempt. It demands more than Annapurna Base Camp and, in several respects, more than Everest Base Camp too — but for trekkers who train properly, respect the acclimatization schedule, and take the pass crossing seriously, it delivers one of the most rewarding long treks anywhere in the world.
