Can I buy good outdoor gear in Peru?

Yes, especially in Cusco which has dozens of outdoor gear shops. Prices are similar to home countries but selection is good. Lima has major international brands but limited outdoor-specific stores.

How quickly do temperatures change with altitude?

Temperature drops about 3.5°F for every 1,000 feet of elevation gain. Flying from Lima (sea level) to Cusco (11,200 feet) means a 40°F+ temperature difference.

What's the biggest clothing mistake tourists make?

Wearing cotton in the mountains. Cotton kills at altitude because it retains moisture and loses all insulating properties when wet. Stick to synthetic or wool fabrics.

Do I need special clothes for Machu Picchu?

Layer for rapid weather changes. Start with base layers, add insulation for early morning, and be ready to strip down to t-shirt by midday. Bring rain gear year-round.

What to wear in Peru's different climates and altitudes

Pack layers for Peru's three distinct climate zones: lightweight breathable clothes for the coast, insulating layers and sun protection for the Andes above 10,000 feet, and moisture-wicking fabrics for the humid Amazon. The key is layering since you'll experience dramatic temperature swings, especially at altitude where it can be 70°F during the day and 30°F at night.

Identify your destinations and elevation. Map out which climate zones you'll visit. Coastal Peru (Lima, Paracas) stays 60-75°F year-round. Andean destinations like Cusco (11,200 feet) and Huacachina have huge daily temperature swings. Amazon regions like Iquitos stay hot and humid 80-90°F with frequent rain.
Pack your base layer system. Bring 2-3 moisture-wicking synthetic or merino wool base layers. These work in all three climates - cooling you in the Amazon, providing insulation in the Andes, and offering comfort on the coast. Avoid cotton which stays wet and cold at altitude.
Add insulation for altitude. Pack a down jacket or synthetic insulated layer for any destination above 8,000 feet. Temperatures in Cusco drop to 30-40°F at night even in summer. A warm hat and gloves are essential for early morning train rides to Machu Picchu or overnight treks.
Choose appropriate footwear for terrain. Bring waterproof hiking boots for mountain treks and Amazon excursions. Pack lightweight sneakers or breathable shoes for coastal cities. Sandals work for Amazon lodges but bring closed shoes for jungle walks to prevent insect bites.
Prepare for intense UV exposure. Pack a wide-brimmed hat, UV-protective sunglasses, and long-sleeve shirts. The sun at Machu Picchu (8,000 feet) is 25% stronger than at sea level. Bring SPF 50+ sunscreen and lip balm with UV protection.
Account for rain in your destinations. Bring a packable rain jacket for the Amazon and Andean wet season (December-March). A rain poncho works better for jungle hikes since it covers your backpack. Coastal Peru rarely sees rain except in the far north.
