This remote expedition requires good physical readiness and the right equipment to ensure safety and comfort.<\/p>\n<p data-start=\"297\" data-end=\"521\">It is highly recommended to spend 2 to 3 days acclimatizing in Cusco or nearby high-altitude areas before starting the trek. This helps your body adjust to the reduced oxygen levels and reduces the risk of altitude sickness.<\/p>\n<p data-start=\"523\" data-end=\"738\">Bring thermal layered clothing to adapt to sudden weather changes, along with gloves, a warm hat, and other cold-weather gear. Temperatures can drop quickly, especially in the early morning and at higher elevations.<\/p>\n<p data-start=\"740\" data-end=\"929\">Proper trekking boots are important, as the terrain is often rocky and uneven. Staying well hydrated throughout the journey is also key to maintaining energy and supporting acclimatization.<\/p>\n<p data-start=\"931\" data-end=\"1079\">Strong sun protection is essential, since UV radiation is intense at high altitude.
