Cochahuasi Animal Sanctuary sits at kilometer 22 on the Cusco–Pisac highway, housing over 40 species of rescued Andean wildlife across 15 hectares of high-altitude terrain. Established in 2007, the conservation center provides permanent refuge for confiscated animals — condors with damaged wings, spectacled bears from illegal trade, vicuñas orphaned by poaching — all unable to return to the wild. The alpacas and llamas here are descendants of working animals surrendered by rural communities, now part of the sanctuary's education and visitor engagement program. The facility operates under Peruvian wildlife protection law, funded entirely by entrance fees and donations. Alpaca trekking Cusco experiences center on guided walks through the sanctuary's wooded enclosures and observation platforms, where visitors approach the camelid herd under keeper supervision. The alpacas, accustomed to human presence through daily care routines, graze freely across sloped pastures bordered by native queñua trees and retama shrubs. Handlers explain fiber grades, breeding lineages, and the distinction between huacaya and suri alpaca varieties — differences visible in fleece texture and ear shape. The sanctuary prohibits uncontrolled feeding or solo entry into animal zones, maintaining protocols that prioritize animal welfare over tourist interaction volume. The broader alpaca trekking Cusco tour portfolio extends into the Sacred Valley, where operators combine sanctuary visits with multi-day treks to Humantay Lake and Ausangate's glacial basins. These routes traverse altitudes between 3,800 and 5,000 meters, demanding acclimatization and physical preparation. Humantay Lake sits in a cirque beneath the Salkantay massif, its turquoise water fed by glacial melt; the trail ascends 400 meters over three kilometers from Soraypampa. Ausangate routes pass seven alpine lakes ringed by colored mineral deposits — red iron oxide, yellow sulfur, green copper — visible only during the dry season between May and September. Chinchero weaving cooperatives and Moray's agricultural terraces appear on valley-floor itineraries, offering context for the historic role of camelid fiber in Inca textile production. Moray's concentric platforms descend 150 meters, creating microclimates that allowed crop experimentation; each terrace level represents a different temperature zone. Ollantaytambo's fortress remains the only Inca town still inhabited, its original street grid and water channels intact beneath modern dwellings. These sites anchor full-day circuits that return to Cusco by evening, while multi-day treks require camping equipment and porter support at designated high-altitude camps.
