Embarking on the Ausangate Trek is an incredible alpine adventure that takes you deep into the glaciated heart of the Peruvian Andes, offering turquoise glacial lagoons, herds of grazing vicuñas, and a profound connection to ancient Quechua culture.
Because the trail regularly exceeds 4,600 to 5,200 meters (15,000–17,000 ft) above sea level, being fully prepared with the right sub-zero clothing and mountaineering gear is essential for your comfort and safety. In this ultimate 2027 guide, Peru by Locals breaks down all the packing essentials to ensure you conquer this demanding trek with confidence.

Ausangate Survival Secret: High mountain campsites like Upis and Ananta drop to -5°C to -10°C (14°F to 23°F) overnight. Sub-zero temperatures drain lithium-ion phone and camera batteries in minutes! Always slip your phone, camera batteries, and portable power bank inside a woolen sock at the bottom of your sleeping bag so your body heat keeps them charged.
Essential Documents for the Ausangate Trek
Before packing your gear, ensure your travel documents are completely in order:
- Original Physical Passport: Required for entry into Peru, official checkpoints, and community toll gates. Always keep it in a secure, waterproof zip-pouch.
- Copies of Important Documents: Bring hard copies and digital backups of your passport, travel insurance policy covering high-altitude trekking up to 5,500m, and your medical contact details.
- Peruvian Soles (Cash): Carry small bills (200–400 Soles) for natural hot springs in Upis and Pacchanta, local community fees, and tipping your local horsemen.
Choosing the Right Bags
During the Ausangate trek, your luggage is managed in two separate systems:
- Daypack (25 to 30 Liters): You will carry this personal pack all day. It holds your rain layers, drinking water, camera, sunblock, gloves, and daily snacks. Look for ergonomic models like the Osprey Talon or Deuter Futura with a supportive hip belt and built-in waterproof rain cover.
- Duffle Bag (Strict 7 kg / 15.4 lbs Limit): Provided directly by Peru by Locals during your pre-trek briefing in Cusco. Pack horses or mules transport this duffle between wilderness campsites, so you will only access it in the morning and evening at camp.

Clothing for the Ausangate Trek
Base Layers and Underwear
- Breathable Underwear (4–6 pairs): Moisture-wicking merino wool or synthetic sports underwear to prevent chafing during long mountain ascents.
- Thermal Base Layers (Next-to-Skin): Snug-fitting merino wool tops and bottoms (e.g., Icebreaker 200–260 gsm or Smartwool) that retain body heat even when damp and resist odor naturally.
Trekking Shirts and Pants
- Technical Trekking Shirts (1 per day): Long-sleeve, quick-drying polyester or nylon shirts with UPF sun protection. Avoid cotton entirely!
- Durable Hiking Pants (2 pairs): Wind-resistant, quick-drying hiking trousers. Water-resistant stretch-woven softshell pants are ideal for high winds.
- Thermal Camp Pants / Sweatpants: A warm, cozy fleece pant reserved exclusively for sleeping inside your tent after a freezing day on the trail.
Outer Layers for Sub-Zero Weather
- Hard Shell Rain Jacket: A rugged, breathable Gore-Tex or 2.5-layer waterproof jacket like The North Face Resolve or Patagonia Torrentshell. Always carry a heavy-duty rain poncho as added insurance against sudden Andean blizzards.
- Heavy Down Insulated Jacket: Temperatures at campsites like Ananta and Ausangate Base often dip between -5°C to -15°C (5°F to 23°F). A high-fill down jacket (700+ fill power) with a hood is indispensable.
- Mid-Layer Fleece Jacket: A Polartec 200 fleece jacket or lightweight synthetic grid-fleece that breathes well during intense uphill climbs.
Accessories for Weather Protection & Footwear
Headgear & Gloves
- UV Wide-Brim Sun Hat: High-altitude UV rays at 4,800+ meters are intense. Protect your face, ears, and neck.
- Warm Beanie & Neck Gaiter (Buff): Fleece-lined wool beanie and a merino buff to shield your throat and nose against piercing glacial winds.
- Inner & Outer Glove System: Lightweight touchscreen fleece liner gloves, combined with heavy-duty waterproof/windproof ski-style outer mittens or Gore-Tex gloves for freezing passes.
Footwear & Socks
- Waterproof High-Ankle Hiking Boots: Sturdy boots with rigid Vibram soles and ankle support are crucial for scree, river crossings, and rocky passes. Make sure your boots are thoroughly broken in before arriving in Peru!
- Camp Shoes: Comfortable lightweight sneakers, down booties, or sandals for relaxing around camp or dipping into natural thermal baths.
- Merino Wool Trekking Socks (4–5 pairs): Heavy cushioned merino wool socks like Darn Tough or Smartwool Mountaineering socks to prevent blisters and keep toes warm.
Sleeping Gear for Sub-Zero Andean Nights
Ausangate campsites are located above 4,300 meters, where frost blankets the ground every night. You will need a winter-rated sleeping bag rated to at least -15°C (5°F). If you do not own a winter mummy bag, Peru by Locals offers professional cold-weather down sleeping bags and thermal liners for rent in Cusco.
Other Essential Gear and Accessories
- Trekking Poles: High-altitude trails around Ausangate feature steep moraine switchbacks. Adjustable trekking poles with rubber tips save your knees and provide essential balance.
- Hydration System: Bring a 2L hydration bladder (Platypus or CamelBak) plus an insulated 1L Nalgene bottle (which can double as a hot-water bottle inside your sleeping bag at night!).
- High-Lumen Headlamp: A reliable headlamp like the Petzl Tikka or Black Diamond Storm with fresh batteries and spare rechargeable cells for camp and pre-dawn summit starts.
- High-Capacity Power Bank (20,000 mAh): Cold mountain air drains lithium phone and camera batteries in hours. Keep your power bank inside your sleeping bag at night!
Personal Gear, Altitude Medication & Hygiene
- Altitude Sickness Medication: Discuss Acetazolamide (Diamox) with your doctor before traveling to Peru. Learn more in our Mal de Altura / Altitude Sickness Guide.

- Blister Kit & First Aid: Compeed blister plasters, moleskin, ibuprofen for high-altitude headaches, and personal medications.
- Biodegradable Toiletries: Biodegradable wet wipes, hand sanitizer, quick-dry microfiber towel, and toilet paper in a waterproof ziplock bag.
