Everest Three Passes Trek Packing List: Complete Gear Checklist

Packing Principles

Because the Three Passes is a teahouse trek, you sleep in lodges and eat cooked meals, so there is no tent, stove or food to carry. But two things make it stricter than lower treks: the sustained high altitude and the icy pass crossings. The rules:

• Layer, don't bulk. Temperatures swing from warm forest near Lukla to far below freezing at Lobuche, Gokyo and the pre-dawn pass climbs. Several thin layers beat one thick one.
• Pack for ice. Unlike a standard Everest Base Camp trek, you cross glaciated passes, microspikes are not optional here, especially for Cho La.
• Keep it light. If a porter carries your duffel, aim for under 10-12 kg; your daypack holds water, warm layers, camera and valuables.

Clothing (the layering system)

Because the itinerary is longer (18-21 days), pack a few more socks and base layers than for a two-week trek, laundry is hard high up.

Footwear, Passes & Gear

• Broken-in trekking boots with ankle support, stiff enough to take microspikes, the single most important item.
• Microspikes (essential) for the icy sections on Cho La and, after snow, Kongma La and Renjo La. An ice axe may help in snowy conditions, ask your guide.
• Trekking poles, strongly recommended for the long, steep pass descents.
• Gaiters to keep snow and scree out of your boots on the passes.
• Camp shoes/sandals for evenings in the lodge.
• Daypack (30-40 L) with a rain cover, and a duffel/kit bag if using a porter.
• Sleeping bag rated to about -15 C (or warmer) for the bitterly cold high nights at Chukhung, Lobuche, Gorak Shep, Dzongla and Gokyo.
• Headlamp + spare batteries, for the pre-dawn Kala Patthar and pass starts.
• Water bottles/bladder (2-3 L) + purification (filter, tablets or SteriPen); insulated bottles resist freezing high up.
• Power bank, charging costs money and is scarce and slow at altitude over three weeks.

Documents, Toiletries & Medical Kit

Documents

• Passport + photocopies, Sagarmatha & Khumbu permits (see permits guide), passport photos, travel insurance with helicopter-evacuation cover to at least 5,600 m, and plenty of cash in Nepali rupees for the long trek.

Toiletries

• High-SPF sunscreen and SPF lip balm (UV is fierce at altitude and on snow), quick-dry towel, biodegradable soap, hand sanitiser, wet wipes, toilet paper, personal hygiene items.

Medical kit

• Blister plasters, painkillers, rehydration salts, anti-diarrhoea and broad-spectrum antibiotics (consult your doctor), throat lozenges for the dry Khumbu cough, any personal medication.
• Acetazolamide (Diamox) if your doctor advises it, important given the sustained altitude, see the altitude sickness guide.

What to Rent in Kathmandu (and Seasonal Tweaks)

You do not need to buy everything. Kathmandu's Thamel trekking shops rent the bulky, expensive items cheaply, typically NPR 100-200/day each:

• Down jacket and -15 C sleeping bag, the two best things to rent if you don't own them.
• Microspikes, trekking poles and duffel bags are also widely available, do not skip the microspikes for this route.

Thamel is also the place to buy last-minute socks, sunscreen and snacks at lower prices than home. Namche Bazaar has gear shops too, a useful backstop, but prices rise with altitude.

Seasonal adjustments

• Autumn (late Sep-Nov): the standard list is ideal; nights are very cold high up, so do not skimp on the down jacket and sleeping bag.
• Spring (Mar-May): standard list, but early spring holds more snow on the passes, so quality microspikes matter, and add strong sun protection.
• Winter (Dec-Feb): add an even warmer sleeping bag, extra thermals, heavier gloves and gaiters, but note the passes are often snow-blocked, see the best time guide.
