Exploring the Amazon rainforest from Iquitos is not a high-altitude mountaineering trek, but it presents unique environmental and physical conditions that require realistic preparation. Dense humidity, muddy trails, high temperatures, and frequent boat boarding define daily field life in lowland Loreto.

Preparation Advice
Relative Humidity
80% to 98% constant humidity year-round.
Moderate – High
Wear synthetic fast-dry fabrics; heavy cotton never dries in the forest canopy.
Ambient Temperature
28°C to 34°C (feels like 38°C to 42°C in direct sun).
Moderate
Drink 3 to 4 liters of water daily supplemented with oral hydration electrolytes.
Muddy Trail Hiking
Deep clay mud requiring tall rubber boots for 2 to 3 hours per hike.
Moderate
Maintain steady foot placement; step into existing boot tracks to prevent twisting ankles.
Boat Boarding & Balance
Stepping on narrow wooden gangplanks and floating docks.
Low – Moderate
Keep both hands free while boarding; accept the guide’s support hand when stepping aboard.
Altitude Comparison: Iquitos vs. Cusco
Unlike Cusco (3,400 m) or the Salkantay Pass (4,630 m), Iquitos sits at just 106 meters above sea level. There is zero risk of altitude sickness (soroche). Your cardiovascular system receives abundant oxygen. However, your body expends energy regulating core temperature through continuous sweating, making proper hydration and mineral replacement essential.
