From Cha’llapampa Village, the Chincana route runs parallel to the beach, climbing gently along an ancient route to the isthmus at Santiago Pampa (also known as Kasapata). Immediately east of the trail is an odd carved boulder standing upright in a small field. This is known as the Piedra Sagrada. There are theories that it was used as an execution block for those convicted of wrongdoing.
