The Humantay Lake tour is one of Peru’s most stunning day hikes. A turquoise glacial lake tucked beneath the towering peaks of the Andes, just a few hours from Cusco, it is sure to leave you in awe. Whether you’re visiting during the dry season or braving the rains for a quieter experience, proper packing can make or break the mood of your adventure.
Here’s your go-to seasonal checklist to help you stay warm, dry, and ready for the altitude, all while keeping your backpack light and your mind focused on what’s important—the view.
Understanding the Seasons in the Andes
Cusco’s weather runs on two main seasons:
- Dry Season (May–September): Crisp, clear days with chilly mornings and strong UV exposure at high altitude.
- Wet Season (October–April): Frequent rain showers, muddy trails, and cloudy skies. But the bonus is far fewer tourists.
Regardless of the season, the altitude (over 4,200 meters at the lake) means temperatures fluctuate fast. Layering is essential.
Dry Season Packing List
Even though skies are clear, mornings can be freezing. You’ll want to layer up for the early hours and be ready to shed a few of those layers by late morning as you hike. Your dry season prep should include:
- Thermal base layers for the cold start
- Mid-layer fleece or insulated jacket for warmth
- Lightweight windbreaker or shell to block morning chill
- Breathable hiking pants or leggings
- Sun hat + sunglasses for strong UV at high altitude
- Sunscreen (yes, even when it feels cold)
- Reusable water bottle or hydration bladder
- Snacks or energy bars (you’ll be glad you brought them)
- Hiking boots or sturdy trail shoes with good grip
- Daypack to carry layers and essentials
Optional but helpful: trekking poles for the steeper parts of the trail.
Wet Season Packing List
Rainy season hikes require waterproof everything and an even greater focus on traction and temperature management. Your wet-season get-up should have these essentials:
- Moisture-wicking base layers (avoid cotton)
- Waterproof jacket with a hood
- Rain poncho or backpack cover to keep gear dry
- Quick-dry hiking pants or waterproof over pants
- Wool socks (bring an extra pair just in case)
- Waterproof hiking boots with ankle support
- Gloves and a warm hat (the wind can be intense at the lake)
- Light scarf or buff for dust and wind protection
- Headlamp or flashlight if starting early or during cloudy days
- Snacks + high-energy food for warmth and stamina
A small dry bag or zip lock pouches are also great for protecting your electronics or passport from moisture.
Altitude Essentials
No matter the season, you’ll be hiking well above 4,000 meters. Acclimatization is key, so spend a couple of days in Cusco or surrounding areas before attempting the Humantay Lake tour.
Make sure to pack:
- Coca candy or coca leaves to help with altitude discomfort
- Altitude medication if recommended by your doctor
- Personal first aid kit(band-aids, ibuprofen, motion sickness pills)
Pro Tips for an Enjoyable Experience
- Start early. Tours often begin at 4:00 am to beat the midday sun and crowds.
- Dress in layers. It’s common to start in a beanie and end in a t-shirt.
- Don’t forget your camera. The vivid color of the lake is unforgettable and very photogenic.
