Pack Everest Base Camp for a 50 to 60F daily temperature swing that you cannot wash your way out of. You climb in bright sun at 45F sweating through your base layer, stop for lunch, and the temperature drops 25F in ten minutes while you sit still in a wet shirt at 15,000 feet. That is how people get hypothermic on a trail that is objectively an easy walk.

You will not do laundry above Namche Bazaar. Water is cold, washing is expensive, and nothing dries in that air. Every garment you bring has to stay wearable for up to two weeks, and that single constraint drives this entire list.

What makes Everest Base Camp different to pack for

The swing, not the cold. Daytime highs in the middle of the route sit around 30 to 50F, which is manageable. Nights at Lobuche drop to 0 to 15F, and at Gorak Shep below that. You are packing for both ends of that on the same day, in the same duffel, at an elevation where your body is running on roughly half the oxygen it is used to.

No laundry. This is the constraint people underestimate. A synthetic base layer worn for four days at altitude becomes genuinely unpleasant and stops performing once it holds moisture. Merino can be worn three to five days without odour and keeps insulating when damp, which is why it is not a preference on this trek but a functional requirement.

Unheated rooms. Teahouse bedrooms have no heating. Interior temperature at night matches outside. Above Dingboche that means you sleep below freezing, in your sleeping bag, usually in your base layers. Your sleepwear and your hiking layers are the same garments, which is why you bring more than one set and rotate.

Weight. A porter carries roughly 22 to 33 pounds for you and you carry a daypack with water, layers and camera. Every item competes for that allowance.

Altitude changes everything. At Gorak Shep you have about half the oxygen of sea level. Zips are harder, fine motor control degrades, and you will not want to dig to the bottom of a duffel. Pack so that the things you need at altitude are reachable.

The packing list

Base layers

The part of the list that matters most, and the part rental packages handle worst.

• Three merino base layer tops. This is the number, not two. One hikes, one sleeps, one stays clean in reserve for the summit push days at Lobuche and Gorak Shep. Rotating them is what keeps you from ever putting on a wet shirt at 15,000 feet. The Roman Trail 100% merino base layer is 17.5 micron superfine, soft enough to sleep in for two weeks without irritation.
• Two merino base layer bottoms. Same rotation logic: one for hiking under trekking trousers, one kept dry for sleeping.
• The lightest of your tops carries the warm Lukla to Namche section, where you will sweat in full sun at 8,000 to 11,000 feet.

Mid layers

• One fleece midlayer. A Columbia fleece is the workhorse and packs down acceptably. This is what you wear over the base layer for most of the walking day above Namche.
• One packable insulated jacket for the evenings from Namche upward and for any rest stop above 4,000 metres.
• One expedition-weight insulated jacket for Lobuche and Gorak Shep nights and for the pre-dawn Kala Patthar push. This is a genuinely heavy down or synthetic parka, not a light puffer, and it is the single warmest item you will own on the trek. Kathmandu rental shops hire these for a few dollars a day, which is the sensible option if you will not use one again.

Outer layers

• One windproof waterproof hardshell with a hood. Mandatory. Wind is a bigger problem than rain on this route, particularly on the Tengboche ridge and the Khumbu valley above Dingboche. A Marmot rain shell covers both jobs.
• Waterproof overtrousers for the high exposed sections and for spring snow.

Footwear

• One pair broken-in waterproof hiking boots with ankle support. Merrell waterproof hiking boots are a reliable option. Do not bring new boots. Twelve days of moraine on unbroken boots is how this trek ends early, and there is no way to fix a blister at 5,000 metres except to stop.
• Four to five pairs merino hiking socks. Darn Tough merino socks resist odour and blistering far better than cotton, and you can rinse a pair at Namche and have it dry by morning. Above that, rotation is all you have.
• Camp shoes. Light trainers or down booties for the teahouse in the evening, because taking boots off matters after eight hours.

Trekking poles

Not optional on this route. Black Diamond trekking poles save your knees on the descent from Dingboche to Namche, which is where most people feel it, and they are genuinely stabilising on the Khumbu glacier moraine between Lobuche and Gorak Shep, where the footing is loose rock the whole way. Collapsible poles that strap to a daypack are what you want.

Sleeping

A sleeping bag rated to at least minus 10C, and minus 15C if you feel the cold. Teahouses provide blankets of variable quality and no heating. Rentals in Kathmandu are cheap and fine. A sleeping bag liner adds warmth and keeps the bag clean across two weeks.

Sun, water and small essentials

• Glacier-grade sunglasses. UV at 5,000 metres on snow is severe and snow blindness is a real risk on the Kala Patthar morning.
• High factor sunscreen and SPF lip balm. You will burn through cloud at altitude.
• A headlamp with spare batteries, for the 4am Kala Patthar start and for teahouses that run generators only in the evening.
• Water treatment. Tablets, drops or a filter. Buying bottled water up the valley is expensive and leaves plastic in a place with no way to remove it.
• Two litres of water capacity minimum. Altitude dehydrates you fast and hydration is part of acclimatising. An insulated bottle beats a bladder, because hoses freeze above Dingboche.
• A power bank, and a bigger one than you think. Teahouses charge by the device and cold murders battery life. Keep your phone in your sleeping bag overnight.
• Wet wipes and hand sanitiser. There are no showers worth the name above Dingboche.
• A basic first aid kit with blister plasters, rehydration salts, painkillers and any altitude medication you have discussed with a doctor.

Altitude is the real risk, not the walking

The EBC trek is a long walk, not a climb. Nobody needs ropes or technical skill. What hurts people is altitude, and it does not care how fit you are.

Acute mountain sickness is the common form: headache, nausea, poor appetite, bad sleep, dizziness. It affects a large proportion of trekkers to some degree. The treatment is to stop ascending, and if it does not improve, descend.

HAPE, high altitude pulmonary oedema, is fluid in the lungs: breathlessness at rest, a wet cough, extreme fatigue. HACE, high altitude cerebral oedema, is fluid on the brain: confusion, loss of coordination, behaving oddly. Both are life-threatening and both require immediate descent. Neither waits for morning.

The rules that actually prevent this. Take the acclimatisation days, which on the standard itinerary are day three at Namche Bazaar and day eight at Dingboche. They are not rest days to be skipped to save money. Climb high and sleep low. Do not gain more than 300 to 500 metres of sleeping elevation per day above 3,000 metres. Drink far more than feels necessary. Avoid alcohol entirely above Namche.

Diamox, acetazolamide, is widely used as a preventive and speeds acclimatisation. It is a prescription decision to make with your own doctor before you travel, not something to start on the trail because somebody in a teahouse offered you one. It is a diuretic, so it increases how much you need to drink.

Descent is the cure. Always. Losing 500 metres of elevation does more in an hour than any drug.

What to wear at each elevation band

Lukla to Namche, 2,860 to 3,440 metres. Warmest part of the trek, often 50 to 65F in the sun. One merino base layer, trekking trousers, shell in the pack. You will sweat here.

Namche to Dingboche, 3,440 to 4,410 metres. Base layer plus fleece while walking, insulated jacket the moment you stop. The Tengboche ridge is where the wind starts being a factor and the hardshell comes out.

Dingboche to Lobuche, 4,410 to 4,940 metres. Base layer, fleece, hardshell while moving. Expedition jacket, hat and gloves in the teahouse, because the dining room is the only heated room and only in the evening.

Lobuche to Gorak Shep and Base Camp, 4,940 to 5,364 metres. Everything, much of the time. The glacier moraine is loose underfoot and the wind is constant. Poles earn their place here.

Kala Patthar, 5,545 metres, pre-dawn. The coldest hour of the trek by a wide margin, in the dark, at the highest point you will reach. Full layering including the expedition jacket, two pairs of gloves, a buff over your face, and a headlamp. This is the one morning where being underdressed is genuinely dangerous rather than uncomfortable.

What not to bring

Cotton anything. It holds moisture against your skin, stops insulating when damp and will not dry at altitude. This includes socks and underwear.

New boots. The single most common trip-ending mistake.

Jeans. Heavy, cold when wet, and useless.

A hairdryer, or anything that needs mains power. Teahouses charge per device from solar and generators.

More than one book. Weight is real. A loaded e-reader is the answer.

A drone without a permit. Flying in Sagarmatha National Park requires permission and equipment has been confiscated.

Single-use plastic water bottles. Treat water instead. The Khumbu has no waste infrastructure and what you carry in stays in.

Permits, flights and the rules that have changed

Two documents. You need a Sagarmatha National Park entry permit and a TIMS card, the Trekking Information Management System registration. The UK Foreign Office confirms both are required for Nepal's main trekking regions. A reputable agency arranges these as part of the package; independent trekkers obtain them in Kathmandu or at Monjo.

A guide or porter is required, not merely advised. Nepal requires foreign independent trekkers to use a local guide or porter, and the UK Foreign Office states this plainly. Beyond the rule, a guide is the single biggest safety factor on this route, because they recognise altitude sickness in you before you do.

One specific scam to know about. The Foreign Office warns of trekking guides taking inexperienced clients too high too fast, then calling in expensive helicopter evacuations from which they take a cut. Be suspicious of unusually cheap packages, use a well-reviewed operator, and understand that a guide pushing you upward against how you feel is a red flag rather than encouragement.

The Lukla flight. Tenzing-Hillary Airport is weather-dependent and cancellations are routine, sometimes for days. Build two or three buffer days into the end of your trip so a delay does not cost you your international flight. In peak season many flights now depart from Ramechhap rather than Kathmandu, which adds a four to five hour pre-dawn drive.

Insurance. You need a policy that explicitly covers trekking to 6,000 metres and helicopter evacuation. Standard travel insurance does not, and a helicopter out of Gorak Shep costs thousands of dollars.

When to go

March to May is spring: warmer, longer days, rhododendron in flower lower down, and the Base Camp climbing season in full swing, which makes the camp itself far more interesting to see. More haze later in the season.

October to November is autumn and the classic window: the clearest mountain views of the year, stable weather, cold nights. Busiest on the trail.

December to February is brutally cold with some teahouses closed, though clear and very quiet.

June to September is the monsoon: cloud, rain, leeches lower down, no views and frequent flight cancellations. Not recommended.

Essential resources for women on the Everest Base Camp trek

Emergency numbers: Police 100. Be aware that Nepal has no central public ambulance service. The UK Foreign Office states plainly that some private providers operate in the main cities and that in an emergency you should contact the nearest hospital directly. On the trail, your guide, your agency and your insurer's emergency line are the people who will actually coordinate a response.

On-trail medical care: The Himalayan Rescue Association operates an aid post at Pheriche, 4,371 metres, staffed seasonally by volunteer doctors who specialise in altitude illness. It is the most important medical facility on the route and it runs altitude awareness talks most afternoons in season, which are worth attending. Details at himalayanrescue.org.np.

Main hospital: CIWEC Hospital, Kapurdhara Marg, Kathmandu 44600, telephone +977 1 4524111. CIWEC has specialised in travel and altitude medicine since 1982 and is the standard referral for foreign trekkers coming off the mountain.

US Embassy: US Embassy Kathmandu, telephone +977 1 423 4000, with an emergency line for US citizens. Website np.usembassy.gov.

US State Department travel advisory: Nepal travel advisory.

UK FCDO travel advice: gov.uk/foreign-travel-advice/nepal.

Official tourism authority: Nepal Tourism Board, ntb.gov.np.

Solo women safety assessment: The Khumbu is one of the more comfortable trekking regions in Asia for a woman, and the requirement to trek with a guide or porter means you are rarely genuinely alone on the trail. Sherpa communities along the route are used to foreign trekkers and harassment is uncommon. The real risks here are not social: altitude is what hurts people, and the second risk is a guide or operator with a financial incentive to push you higher than you should go, which is why you choose a well-reviewed agency rather than the cheapest quote and treat a helicopter suggestion with scepticism unless you have symptoms. Teahouse rooms have thin walls and simple latches, so bring a small padlock for your duffel and keep your passport, permits and cash on you rather than in the room. Tell your guide honestly how you feel each morning, because understating a headache to avoid seeming weak is the single most dangerous thing you can do on this trek.
