0 High in the Peruvian Andes lies one of nature’s most surreal creations – the rainbow-striped ridges of Vinicunca. Known to travelers as Rainbow Mountain, this destination has exploded in popularity over the past decade, thanks to its incredible colors and stunning panoramic views. But what many don’t realize before they arrive is how challenging the trek can be.
At over 5,000 meters above sea level, the journey to Rainbow Mountain is no walk in the park. To ensure you enjoy the views rather than suffer the climb, you need to be properly prepared. Whether you’re doing a day trip from Cusco or combining it with other high-altitude hikes like the one to Humantay Lake, having the right gear can make or break your experience.
Here’s your complete packing guide to help you tackle the trek in comfort and style.
Why Packing Right Matters for Rainbow Mountain
The trail to Rainbow Mountain may only be a few kilometers long, but its elevation and terrain demand respect. You’ll be walking in thin air, with weather that can shift from sunny to snowy within an hour. Unlike more gradual treks, this one gains altitude quickly, meaning there’s little time for your body to adjust.
Even short hikes in this region – like the one to the glacial waters of Laguna Humantay – require smart packing. Cold mornings, powerful UV rays, wind chills, and the risk of altitude sickness all come into play.
The key is layering, hydration, and knowing what not to bring.
Clothing Essentials
Let’s start with what you’ll wear. Think layers, quick-drying materials, and protection from both the sun and wind.
1. Base Layer
This is your first line of defense. A moisture-wicking thermal top will keep sweat off your skin and help regulate body temperature.
- Long-sleeved thermal shirt (synthetic or wool)
- Thermal leggings (especially for colder seasons)
2. Mid Layer
Insulation is important, particularly in the early morning when temperatures often drop below freezing.
- Fleece or light insulated jacket
- Down or synthetic puffy jacket (compressible for packing)
3. Outer Layer
Weather changes fast in the Andes. Be ready for wind, rain, or snow.
- Waterproof and windproof jacket
- Rain poncho (especially useful during the wet season)
4. Hiking Pants
Avoid jeans or cotton – they don’t dry well and get heavy when wet.
- Lightweight trekking pants (zip-off versions are handy)
- Thermal leggings underneath if needed
5. Accessories
Small items make a big difference.
- Wool or thermal hat (covers ears)
- Buff or neck gaiter (can be used as a mask or scarf)
- UV-protective sunglasses
- Warm gloves (especially outside the dry season)
- Cap or wide-brim hat for sun protection
Footwear for High-Altitude Trails
Rainbow Mountain’s trail can be muddy, snowy, or rocky depending on the season. You’ll need good grip and ankle support.
- Hiking boots – Waterproof, broken-in, with ankle support
- Wool or thermal socks – Bring a spare pair just in case
- Gaiters (optional) – Useful in rainy or snowy weather
Gear and Day Pack Essentials
You’ll want a light backpack with room for food, extra layers, and personal items. If you’re on a guided tour, some of this may be included, but it’s good to be self-sufficient.
1. Daypack
A 20–30L backpack with padded shoulder straps and waist belt is ideal.
- Rain cover – many packs include one
- Hydration bladder or water bottle (at least 2L capacity)
2. Snacks and Hydration
Altitude can suppress your appetite, but it’s vital to eat and drink regularly.
- Electrolyte tablets or sports drinks
- Energy bars, nuts, dried fruits, or chocolate
- Coca candy or coca tea (helps with altitude)
3. Sun Protection
UV rays are intense at high altitudes – even on cloudy days.
- Sunscreen (SPF 50+)
- Lip balm with SPF
- Sunglasses with UV protection
4. Personal Health Items
Even fit hikers can struggle with the thin air. Be ready.
- Personal medication (especially if prone to altitude sickness)
- Sorojchi pills (local altitude tablets)
- Motion sickness remedies (for the winding drive)
- Basic first aid kit – band-aids, pain relievers, antiseptic wipes
- Tissues or toilet paper
- Hand sanitizer
Optional but Useful Items
While not strictly necessary, these items can improve your experience:
- Trekking poles – Great for steep sections and knee support
- Power bank – Cold temperatures can drain phone batteries fast
- Camera or GoPro – The scenery is once-in-a-lifetime
- Travel towel or scarf – Can be used for warmth, sitting, or drying off
- Extra cash – For horse rentals, local snacks, or tips
Packing for the Season: Wet vs Dry
Dry Season (May to September)
- Clear skies and cold mornings
- Expect strong sun and wind
- Layers are key – mornings are freezing, afternoons are mild
Wet Season (October to April)
- Daily rain showers, muddy trails
- Waterproof gear is essential
- Trails may be snow-covered in higher sections
While the dry months are ideal for visibility, treks to Vinicunca and nearby glacial lakes remain popular in the off-season too – just come prepared to get wet and possibly ride a horse if the trails are too slippery.
What Not to Bring
You’ll thank yourself for packing light. Leave these behind:
- Heavy cameras (unless you’re a professional)
- Cotton clothing (it absorbs moisture)
- Valuables or unnecessary electronics
- Flip flops or casual shoes
- Large backpacks (your tour will likely have weight limits)
What About Humantay Lake?
If you’re also hiking to Humantay Lake during your trip, much of this same packing advice applies. That trek, although shorter, also climbs quickly and reaches altitudes near 4,200 meters. The trail to Laguna Humantay can be steep and dusty in the dry season or muddy and slick during rains.
Make sure to bring:
- Layers for cold, early mornings
- Plenty of water
- Hiking boots and trekking poles
- Warm gloves and hat (especially in the shoulder seasons)
- Snacks to recharge at the top
Even though it’s often done as a day trip, the hike can be physically demanding due to the altitude. Pace yourself, stay hydrated, and take breaks as needed.
Last-Minute Tips Before You Go
- Start early – Most Rainbow Mountain treks begin at 3–4 AM. Be packed and ready the night before.
- Acclimatize – Spend at least 2–3 days in Cusco or the Sacred Valley before attempting high-altitude hikes.
- Listen to your body – If you feel dizzy, nauseated, or weak, alert your guide immediately.
- Bring layers even if it’s sunny – Conditions change fast in the mountains.
- Don’t forget travel insurance – Especially for high-altitude treks.
Final Thoughts
The trek to Rainbow Mountain is more than a hike – it’s an unforgettable journey through some of Peru’s most dramatic scenery. From red-hued valleys to snowcapped peaks, the landscape is otherworldly. But with the beauty comes challenge. The thin air, unpredictable weather, and rugged terrain demand respect.
Packing smart is the simplest way to ensure your focus stays on the stunning views, not on shivering, sunburn, or blisters. Whether you’re adding this to your Peru adventure alongside hikes to places like Laguna Humantay, or making it the highlight of your trip, a well-prepared backpack makes all the difference.
So pack wisely, lace up those boots, and get ready to climb high and see colors you never knew existed in nature.
Your adventure to one of the most colorful corners of the Andes awaits.
