Maras is a town in the Sacred Valley of the Incas, in the Cusco Region of Peru. It lies about 40 kilometers north of Cusco and is the seat of the eponymous district.
The town is best known for its salt evaporation ponds, which have been in use since Inca times. The ponds lie about four kilometers north of the town center, down a canyon that descends to the Rio Vilcanota and the Sacred Valley of the Incas.
There are over 5,000 salt ponds. Some are owned by families, while others are unused.
