From the four-day Poon Hill sunrise loop to the full Annapurna Circuit over Thorong La — ten Annapurna routes ranked by time, effort and reward.
The Annapurna Conservation Area (7,629 km², Nepal's largest protected area) packs more distinct treks than any other range on Earth. All routes below run on the ACAP permit (NPR 3,000) plus a TIMS card (NPR 2,000 for independent trekkers). Distances and day-counts assume the classic teahouse pace with an acclimatisation day wherever altitude demands it.
1. Ghorepani–Poon Hill (4–5 days, 3,210 m)
The Himalaya's greatest sunrise for the effort: 3,000 stone steps through rhododendron forest to a viewpoint tower facing Dhaulagiri to Machhapuchhre. Exit through the Gurung heritage village of Ghandruk. Ideal first trek — teahouses are plentiful and the altitude benign.
Choosing a route by experience rather than reputation
The most famous Annapurna itinerary is not automatically the right one. Begin with available days, previous multi-day walking, comfort with cold, and the highest sleeping altitude—not with a photograph of the finish. Poon Hill and lower village routes offer teahouse trekking without a very high pass. Annapurna Base Camp reaches above 4,000 metres and enters terrain exposed to snow and avalanche conditions. Mardi Himal climbs a narrower ridge with fewer settlement options. The full circuit crosses Thorong La at 5,416 metres and requires a conservative acclimatisation schedule. Nar and Phu add restricted-area administration, remoteness and another high crossing. Road access has shortened several classic approaches, but saving road days does not safely compress acclimatisation. Compare routes using the point where you sleep, the longest ascent, escape options and seasonal hazards. A shorter trek completed with time to observe villages and weather is a better journey than a prestigious circuit forced into an unsafe schedule.
2. Annapurna Base Camp (7–11 days, 4,130 m)
A week from rice paddies into a glacial amphitheatre ringed by ten summits. The stone-stair grind through Chomrong is the price; the sanctuary bowl below Annapurna I (8,091 m) is the reward. Machhapuchhre, the sacred fishtail, guards the entrance — unclimbed by law.
Permits and guide rules must be checked for the exact itinerary
The Annapurna Conservation Area is managed through a permit system, while trekking administration can also involve TIMS and, for specified valleys, restricted-area permits issued through authorised agencies. Rules, fees, checkpoints and guide requirements change, and different routes inside the broad Annapurna region do not always share the same conditions. Nar and Phu, for example, cannot be planned as if they were an ordinary extension of Poon Hill. Before paying an operator, write down every district, conservation area and restricted zone on the route; ask which authority issues each document, whether the fee is included, and where the original permit must be shown. Confirm the current answer with the National Trust for Nature Conservation, Nepal Tourism Board or Department of Immigration rather than relying on an undated blog. Carry passport photographs or digital copies only as currently requested, keep permits accessible at checkpoints, and preserve receipts. A legitimate guide or agency should explain the paperwork without inventing an 'expedition permit' for a normal trekking path.
3. The full Annapurna Circuit (12–18 days, 5,416 m)
Nepal's classic loop: subtropics to the Tibetan-style desert of Mustang over Thorong La, the highest pass of the big circuits. Acclimatise at Manang, cross pre-dawn, descend to Muktinath's shrine. Road building shortens either end each year — check the current route.
Acclimatisation is built around sleeping altitude
Altitude illness is not predicted by fitness, age or enthusiasm. Above roughly 2,500 metres, the body needs time to adjust to reduced oxygen pressure; rapid increases in sleeping altitude raise risk even when the walker feels strong during the day. On the circuit, Manang is used for acclimatisation because it allows a rest or side-walk day before the approach to Thorong La. On sanctuary routes, symptoms can appear as walkers rise quickly from warm low valleys. Headache combined with nausea, unusual fatigue, dizziness or poor sleep deserves attention. Worsening symptoms, confusion, loss of coordination or breathlessness at rest require descent and medical help. Medication and oxygen can support a response but do not make continued ascent safe. Keep itinerary flexibility, hydrate normally without forcing excessive water, avoid alcohol during major altitude gains and tell companions how you feel. The most important schedule is not kilometres per day but the sequence of sleeping elevations and the practical ability to descend.
4. Mardi Himal (5–7 days, 4,500 m)
The circuit's best-kept ridge walk: a forest-to-alpine spur beneath Machhapuchhre's south face with far fewer teahouses than ABC. High Camp (3,580 m) to the viewpoint is a stiff pre-dawn climb for a face-to-face with the fishtail.
Thorong La is a weather decision, not a guaranteed appointment
The crossing is usually attempted early because winds strengthen and afternoon weather can deteriorate, but an early start does not neutralise snow, ice, cold or poor visibility. Conditions at a lodge do not prove the pass is safe. Ask lodge owners, guides and walkers arriving from the opposite direction; compare reports rather than treating one optimistic answer as permission. Carry layers that remain usable while moving slowly, protect water from freezing and keep a headlamp available after dawn. If heavy snow, illness or delay makes the margin too small, wait or retreat. The circuit can be reorganised; a rescue cannot be assumed. Reverse-direction claims also need care: gradient, acclimatisation and lodge spacing differ, and there is no universal direction that suits every group. The pass is one day within a long cultural and ecological route. Turning around before it does not erase the valleys already walked, while pushing through deteriorating conditions can endanger guides and rescuers as well as the traveller.
5. Khopra Danda–Kayer Lake (7–9 days, 4,650 m)
The community-lodge alternative to Poon Hill, running a ridge with Dhaulagiri views and ending at the sacred Kayer Lake beneath Nilgiri. Lodges are village-run — your fees stay in the communities.
Road building has changed the classic circuit
The Annapurna Circuit described in older books included long approaches through valleys now reached by rough roads. Jeeps can reduce walking time, supply lodges and improve local access to markets, schools and health care. They also add dust, traffic and road walking to sections once experienced as foot trails. The response should not be nostalgia that treats local transport as damage created for outsiders. Instead, use current maps to identify alternative footpaths, village-side routes and realistic trailheads. Some trekkers begin higher to avoid roads, but a fast vehicle ascent can remove useful acclimatisation days. Others combine walking and transport strategically, spending saved days in Manang, side valleys or community lodges. Ask where vehicles actually operate in the current season; landslides and maintenance can change the answer. A modern circuit is a negotiation between historic trade paths, living transport needs and a trekking industry adapting around both.
6. Muldai Viewpoint (4–6 days, 3,640 m)
A newer, gentler ridge above the Modi valley — arguably the finest 360° panorama in the range at an altitude most walkers can reach without acclimatisation drama. Combine with Poon Hill for a week.
Teahouse trekking still requires preparation
A lodge network reduces the need to carry tents and a full kitchen, but it does not turn a Himalayan route into an urban hotel corridor. Rooms may be unheated, plumbing can freeze, charging and hot showers may cost extra, and menus narrow as supplies travel farther. Carry a sleeping bag appropriate to season, water treatment, headlamp, personal medication, sun protection and enough cash for the full route plus delay days. Do not depend on card terminals or mobile data outside larger settlements. Order meals early when a lodge is busy, and understand that dal bhat, noodles, potatoes, eggs and soups are practical mountain fuel rather than a limitless menu. Refill water instead of buying repeated plastic bottles where safe treatment is available. A porter should have agreed equipment, insurance and load conditions through a responsible employer. Comfort is welcome, but the resilience of the route still depends on workers, pack animals, fuel and food moving through difficult terrain.
7. Poon Hill + ABC combined (10–14 days)
The greatest-hits package: sunrise ridge first, sanctuary second, exiting via Jhinu's natural hot springs — the classic soak after ten days of stone stairs.
The conservation area is also a lived cultural landscape
Annapurna is Nepal's largest conservation area, extending from humid foothills through trans-Himalayan country. Its settlements include Gurung, Magar, Thakali, Manangi and other communities with distinct languages, architecture, ritual traditions and migration histories. A stone village or monastery is not scenery placed beside the trail. Ask before entering religious rooms or photographing people, walk around mani walls in the locally indicated direction, and avoid blocking work with staged portraits. Community-run lodges and local guides can keep more income along the route, but 'community' should not be used as a marketing label without asking who owns and manages the service. Water, fuelwood and waste systems are under pressure where visitor numbers concentrate. Carry out batteries and difficult packaging, use refill stations, keep soap away from streams and follow local waste instructions. Conservation succeeds when residents gain durable benefits and retain authority over the landscapes visitors have come to admire.
8. Nar–Phu Valley + Circuit (16–20 days, 5,320 m)
Detour into the restricted medieval villages of Nar and Phu (permit USD 100/week) before rejoining the circuit at Kang La. Two extra passes, two lost valleys, zero crowds.
A realistic decision checklist before departure
Confirm the route and alternative exit, permits, guide status, insurance altitude limit and emergency contacts. Record each planned sleeping altitude and insert acclimatisation where the gain demands it. Check whether the season brings monsoon landslides, winter snow, spring storms or crowded autumn lodges. Review footwear before travel rather than discovering blisters on stone steps, and train for repeated descents as well as ascent. Share the itinerary with someone outside the group and update them when the route changes. Carry enough cash and medication for weather delays. Most importantly, decide in advance that illness and unsafe conditions can end the ascent without becoming a personal failure. The Annapurna region offers many linked routes; flexibility is one of its strengths. Good preparation does not remove uncertainty. It creates enough time, equipment and shared judgement to respond to uncertainty without turning a manageable change into an emergency.
9. Annapurna Circuit in reverse (12–18 days)
East-to-west means climbing Thorong La from the gentler Mustang side and descending to Manang — many knees and lungs prefer it, and the scenery sequence ends with the green valleys rather than the road.
Photography and drones in mountain communities
Ask before photographing residents, ceremonies, monastery interiors or people working with animals. A long lens does not remove the need for consent when a person is identifiable and central to the image. Drone rules involve aviation restrictions, protected-area permission, privacy and local acceptance; carrying a drone does not establish permission to fly it. Check current requirements with the relevant authorities and leave it packed when wildlife, rescue aircraft, settlements or sacred sites could be disturbed. Good trail photography records weather, labour and landscape without turning every encounter into content. Share images when promised, keep geolocation away from vulnerable wildlife and avoid blocking narrow paths while composing a shot.
10. The Kali Gandaki gorge escape (3–4 days)
Not a high trek but a gorge one: Muktinath to Jomsom to Tatopani's hot springs along the world's deepest river gorge, apple orchards of Marpha and the salt-trade villages that built them.
