The Sacred Valley of the Incas was undoubtedly a key area of settlement to the Incas. Its agreeable climate and fertile plains make a rare and fruitful combination for the high Andes. It was also the route to the jungle and therefore an area with access to the fruits and plants of the tropical lowlands. The Sacred Valley served as a buffer zone, protecting Cusco from incursions of the Antis, the fierce jungle tribes who from time to time raided the highlands. Today the Sacred Valley remains a lush agricultural region supplying the city of Cusco with much of its produce such as maize, fruit and vegetables.
Most people visit the Sacred Valley as part of an organized tour.
Departures are usually on the market days of Tuesday, Thursday and Sunday, although some companies are now leaving everyday. If you only have one day to visit the Sacred Valley you'll find the convenience of the tour well worth while. Ask in some of the tour agencies and speak to the guide. Always get a written contract of services. If you want to get away from the organized tours and be a little bit more independent you can visit the Sacred Valley easily by local bus on your own.
