How to pack for a high-altitude trek in the Himalayas
Pack using a three-layer system—base, mid, and outer—and limit your total gear weight to 10-12kg. You need high-quality technical fabrics that dry quickly and can handle temperatures ranging from 20°C in the valleys to -15°C at high passes.
- Select your luggage. Bring one 40-50L backpack for your day gear and one sturdy, water-resistant duffel bag (80-90L) for your porter to carry. The duffel should be lockable and durable enough to be tossed on top of a bus or tied to a yak.
- Master the layering system. Bring a merino wool base layer (top and bottom), a fleece or lightweight down jacket for the mid-layer, and a heavy down jacket (rated to -15°C) for evenings. Always pack a reliable waterproof and windproof shell jacket.
- Protect your feet. Use broken-in, waterproof trekking boots with good ankle support. Bring three pairs of thick merino wool hiking socks and one pair of lightweight camp shoes or sandals to let your feet breathe at the teahouses.
- Manage your water. Do not rely on plastic bottles. Bring two 1-liter reusable wide-mouth bottles and a chemical purification system like chlorine dioxide tablets or a LifeStraw filter. Cold water freezes; keep bottles inside your jacket or in an insulated sleeve.
- Organize with dry bags. Pack all your clothes inside individual dry bags or thick plastic liners. If your porter’s bag gets soaked during a mountain storm, your sleeping clothes must remain bone dry.
- Do I need a professional trekking pole?
- Yes. The descent is often harder on your knees than the ascent. A collapsible trekking pole is essential to save your joints.
- Can I charge my electronics in the mountains?
- Most teahouses have electricity, but they charge $2-$5 per device per hour. Bring a solar-compatible power bank or extra batteries.
- What is the one thing people regret forgetting?
- A decent book or deck of cards for the long, cold evenings in the teahouse common rooms.
