Chillca is a small highland community located in the Peruvian Andes near the Ausangate mountain, one of the most sacred peaks in Inca tradition. Sitting at an elevation of approximately 14,100 feet, this remote village is home to Indigenous Quechua-speaking alpaca herders and artisans who maintain a traditional lifestyle in a harsh yet environment. The surrounding terrain features expansive green valleys, grazing pastures, and snow-capped peaks, offering a glimpse into the resilience of high-Andean culture.

The town of Chillca has gained recognition for its involvement in sustainable tourism and eco-trekking initiatives, especially along the Ausangate and Rainbow Mountain routes. Visitors can stay in locally operated lodges, learn about Andean weaving and llama caravan culture, and witness life in one of Peru's most pristine alpine settings.
