Essentials for Cusco in July
Warm Wool Hat or Beanie
Nights and early mornings are freezing, and a good hat will prevent significant heat loss.
Thermal Base Layers (long-sleeved top and bottoms)
These are crucial for warmth during cold nights and early morning excursions, especially if you're hiking.
Fleece Jacket or Mid-Layer
Provides excellent insulation and can be worn under a heavier jacket or on its own during cooler daytime hours.
Waterproof and Windproof Outer Jacket
Essential for protection against strong winds and any unexpected, though rare, precipitation, and for added warmth.
Comfortable Walking Shoes with Good Grip
You'll be doing a lot of walking on uneven cobblestone streets and potentially dusty trails, so comfort and traction are paramount.
Sunscreen (SPF 30+)
Due to Cusco's high altitude, the sun's rays are much stronger and more harmful, even on cloudy days.
Sunglasses
Protects your eyes from intense UV radiation and glare, especially important with the clear skies.
Lip Balm with SPF
High altitude and dry air can quickly lead to chapped lips, so protection and moisture are vital.
Small Backpack (daypack)
Perfect for carrying extra layers, water, snacks, and your camera during daily excursions.
Reusable Water Bottle with Filter
Staying hydrated is important at altitude, and a filter ensures you can safely refill from various sources, reducing plastic waste.
Portable Power Bank
Keep your phone and other electronic devices charged, especially during long days of exploring or if you're venturing outside the city.
Pro tips
Stay Hydrated
The dry air and altitude can lead to dehydration. Carry a reusable water bottle and sip frequently throughout the day.
Protect Yourself from the Sun
Even if it feels cool, the sun at altitude is incredibly strong. Apply sunscreen liberally, wear a wide-brimmed hat, and sunglasses.
Layer, Layer, Layer
This is the golden rule for packing for Cusco in July. Dress in multiple layers that you can easily add or remove as temperatures fluctuate dramatically throughout the day.
Embrace Coca Leaves
Many locals chew coca leaves or drink coca tea to help with altitude sickness. It's readily available and generally safe to try in moderation.
