Dead Woman's Pass, known as Warmiwañusca in Quechua, is the highest point on the Inca Trail to Machu Picchu in Peru. Standing at 4,215 meters (13,828 feet) above sea level, it offers stunning views of the surrounding Andes mountains. Hikers often experience altitude sickness due to the elevation, making the ascent challenging. The name "Dead Woman's Pass" is derived from the shape of the mountain, which resembles a woman lying on her back. This pass is a significant landmark for trekkers, marking the halfway point of the journey to the ancient Incan city of Machu Picchu.
