Understanding the Three Passes Trek

This trek isn’t your average Sunday stroll. It takes you through three high mountain passes: Kongma La (5,535m), Cho La (5,420m), and Renjo La (5,360m). It’s physically demanding and remote, meaning access to gear or supplies is almost nonexistent after you begin. Packing well isn’t just convenient—it’s survival.

How to Pack Smart: Less is More

Don’t think “what if I need this?” Think, “what will I definitely need?” Overpacking is a rookie mistake. Use this rule: If it doesn’t serve at least two purposes, leave it. Every extra pound slows you down and wears you out. Think of your backpack as prime real estate—only essentials can stay.

Clothing Layers: The Golden Rule

Mountains are unpredictable. One moment it’s sunny, the next you’re caught in snow. That’s why layering is life. The three-layer system helps regulate body temperature and protects you from the elements.

Base Layers: Your Second Skin

These wick sweat away and keep you dry, which is crucial at high altitudes.

Essentials:

2–3 moisture-wicking t-shirts (merino wool is gold)

2 thermal tops and bottoms

Sports bra (for women)

Lightweight long-sleeve shirt (for sun protection)

Insulation Layer: Stay Toasty

This is your cozy middle layer. Fleece or down traps warmth.

Essentials:

Fleece jacket or pullover

Lightweight down jacket (compressible)

Insulated vest (optional but helpful)

Outer Layer: Wind and Waterproof

This is your shield. Protects from snow, wind, and rain.

Essentials:

Hardshell waterproof jacket with a hood

Waterproof pants

Packable rain poncho (optional but handy)

Bottoms: Pants That Perform

Your legs work hard, so dress them well.

Essentials:

1–2 trekking pants (quick-dry, stretchable)

1 fleece pant (for evenings)

1 thermal legging (for sleeping or extra cold days)

Waterproof over-pants

Footwear: Trusty Shoes for Tough Terrain

Blisters are the enemy. Good boots are your best friends.

Essentials:

High-ankle trekking boots (broken in before the trip)

Camp shoes or sandals (for tea house wear)

3–4 pairs of moisture-wicking socks (including wool)

Accessories: Small Items, Big Impact

Often overlooked, these save you from headaches—literally.

Essentials:

Warm hat/beanie

Buff or neck gaiter

Sunglasses (UV-protected)

Waterproof gloves (plus liners)

Trekking poles (foldable)

Headlamp with extra batteries

Sleeping Gear: Rest Matters

Tea houses provide beds, but not always enough warmth.

Essentials:

Four-season sleeping bag (rated to at least -10°C)

Sleeping bag liner (adds warmth and hygiene)

Earplugs (trust us on this one)

Backpack and Daypack: Carry Smart

Weight distribution matters.

Essentials:

50–65L trekking backpack (with rain cover)

20–25L daypack (for short hikes or as carry-on)

Dry sacks or zip-lock bags (to separate wet/dirty clothes)

Toiletries and Hygiene Essentials

You’re not climbing Everest, but staying clean helps morale.

Essentials:

Toothbrush, toothpaste

Biodegradable soap and shampoo

Quick-dry towel

Hand sanitizer

Wet wipes and toilet paper

Lip balm and moisturizer (cold air is brutal)

Sunscreen (SPF 50+)

Health and First Aid Kit

Altitude sickness is real. Be prepared.

Essentials:

• Diamox (for altitude)

• Ibuprofen or paracetamol

• Band-aids, blister pads

• Rehydration salts

• Antiseptic cream

• Personal medications

• Altitude sickness guide (basic understanding helps)

Electronics and Power Backup

You won’t get charging stations often.

Essentials:

Power bank (10,000 mAh minimum)

Solar charger (optional but smart)

Universal adapter

Camera or phone with enough storage

Extra SD cards and cables

Offline maps on your device

Documents and Permits

Don’t get turned away at a checkpoint.

Essentials:

Passport (with 6 months validity)

TIMS Card

Sagarmatha National Park Permit

Passport-sized photos (for emergency)

Travel insurance (with trekking cover)

Photocopies of all documents

Snacks and Hydration Essentials

Fuel your body and stay hydrated.

Essentials:

Water bottles (2L total) or hydration bladder

Water purification tablets or filter

Electrolyte packets

Energy bars, trail mix, chocolates

Instant coffee/tea (if you’re picky)

FAQs

1. How cold does it get on the Three Passes Trek?
Temperatures can drop below -10°C at night, especially over the passes. Pack for extreme cold, even in peak seasons.

While it’s possible to go solo, hiring a guide adds safety and enhances the experience—especially if the weather turns rough or you’re unfamiliar with altitude trekking.
