Uyuni Packing List: How to Pack for Extreme Cold and High Altitude

Packing for the Salar de Uyuni is confusing. You check the weather app and it says the high is 18°C (64°F) and the low is -15°C (5°F). You look at Instagram and see people in T-shirts doing yoga poses, but then you swipe and see someone else wrapped in a North Face parka looking miserable.

Here is the reality check: The Bolivian Altiplano doesn’t play by normal rules. You will often experience four seasons in a single day. The sun at 3,600 meters is intense—it cooks you. But the second a cloud rolls in or the sun sets, the temperature drops off a cliff. The wind on the salt flat is violent; it cuts right through denim.

If you pack too light, you risk hypothermia (not a joke). If you pack too heavy, you’re dragging a suitcase across the desert for no reason. This guide cuts through the noise and tells you exactly what you need to survive.

The Golden Rule: The Layering System

Forget the massive arctic coat. The secret to not dying of discomfort in Uyuni is the “Onion Principle.” You need thin layers you can peel off and put back on constantly. Expect to change your outfit three times before dinner.

1. The Base Layer (The Second Skin)

This is the most critical layer. It touches your skin.

• Do NOT wear Cotton: Cotton kills. It soaks up sweat and holds it against your body. When the temp drops, that wet t-shirt turns into a block of ice.
• Wear Merino Wool or Synthetics: You need thermal leggings and a long-sleeve top. Merino is king because it doesn’t smell after three days (trust me, this matters). Synthetic blends like Uniqlo Heattech work fine if you’re on a budget.

2. The Mid Layer (Insulation)

This layer’s only job is to trap heat.

• Fleece Jacket: A simple zip-up fleece for mornings.
• Down Sweater / Puffer Vest: Highly recommended. A lightweight down jacket squishes down to nothing in your bag but keeps you insanely warm.

3. The Outer Shell (Protection)

This protects you from the wind, rain, and snow.

• Windbreaker: The wind on the open salt flat is relentless. Even if it’s sunny, the wind chill will wreck you. You need a shell that stops the air.
• Pants: No jeans. Just… no. They are stiff, cold, and if they get wet, game over. Trekking pants or athletic pants with thermals underneath are the move.

Extremities: Head, Hands, and Feet

Your body is smart; it keeps your heart warm by sacrificing your fingers and toes. These are the first things that will hurt.

Headgear

• Beanie (Wool Hat): Mandatory. You lose heat through your head. You need this for sleeping and for the sunrise geyser tour.
• Buff / Scarf: The air is dry and dusty. A neck gaiter keeps your throat warm and you can pull it up over your nose to keep the dust out.
• Sun Hat: Mid-day sun is brutal. Bring a baseball cap.

Gloves

Photographers, listen up. You need a two-glove system:

• Thin Liners: Touch-screen compatible. So you can use your phone without exposing skin to -10°C air.
• Heavy Mittens: To wear over the liners when you’re just standing around.

Footwear Strategy

This depends entirely on when you go. (Unsure? Check our guide on the best time to visit Uyuni).

• Dry Season (May-Nov): Hiking boots or sturdy sneakers. The salt is hard. Hiking boots are better if you want to climb the islands.
• Wet Season (Dec-Apr): This is crucial. If you want the mirror effect, you are walking in 10cm of saltwater. Saltwater destroys leather. It ruins canvas.
  • Wellingtons (Rubber Boots): Some tours have them. Most don’t fit right. If you have big feet, bring your own waterproof covers.
  • Spare Socks: Bring twice as many as you think you need. Wool is best.

Toiletries and Health Kit

In the desert, small problems become big problems. Pharmacies? They don’t exist out here.

Sun Protection (Critical)

The UV at 4,000 meters is nuclear. The white salt reflects it right up your nose.

• Sunscreen: SPF 50+. Reapply every 2 hours or you will burn.
• Lip Balm: With SPF. Your lips will crack and bleed within 24 hours without this.
• Sunglasses: Polarized is best. The glare causes “snow blindness” which feels like sand in your eyes. It hurts.

Skin Care

• Moisturizer: The humidity is 0%. Your skin will turn to lizard scales. Bring heavy lotion.
• Nasal Spray: The dry air causes nosebleeds. A saline spray helps.

The Medicine Cabinet

Check our full Health and Safety guide, but pack:

• Paracetamol / Ibuprofen: For the altitude headache.
• Diamox: If your doctor prescribed it.
• Motion Sickness Pills: It’s bumpy.
• Imodium: Stomach bugs happen. Be ready.

Electronics and Gadgets

Cold kills batteries. Lithium-ion hates freezing temps.

• Power Bank: A big one (20,000mAh). Electricity in hostels is spotty. Outlets are scarce.
• Extra Batteries: Keep spares inside your jacket, against your body heat. If they get cold, they die.
• Tripod: For the stars. The wind will knock over a cheap one.
• Headlamp: Electricity cuts out at night. You need this to find the bathroom.
• Offline Entertainment: No WiFi for 3 days. Download your Spotify and Netflix before you leave civilization.

The “Comfort Factor”: How Your Tour Affects Your Packing

The amount of crap you have to carry depends on how much you paid for your tour.

For Standard/Budget Tours

You are staying in basic shelters. Often unheated.

• Sleeping Bag: Mandatory. You can rent one, but bring a liner. The provided blankets are heavy but not warm enough for -15°C.
• Towels & Soap: Bring your own.
• Toilet Paper: Never provided. Bring 2 rolls.

For Luxury / Private Tours

Upgrade and save your back. Travelers on our Luxury Tours stay in hotels like Palacio de Sal. Central heating. Electric blankets. Hot water.

• No Sleeping Bag needed.
• No Towel needed.

Hate packing? If all this sounds like too much work, just do a 1-Day Private Tour. See the salt, skip the freezing night.
