Making arrangements to see the Sacred Valley through a tour operator can be an excellent way to get to know this spectacular valley rich in Inca ruins, agriculture and magnificent views. Hiking tours are especially popular in this area: the Sacred Valley offers literally some of South America's most beautiful and historic hikes. Another extremely popular option are archaeological tours in the Sacred Valley. These are best for travelers who want to see as many of the incredibly preserved Inca ruins throughout the valley as possible. Aside from purchasing Sacred Valley tours in Cusco, for those who are a little more adventurous and perhaps have a decent smattering of Spanish, it is possible to base yourself in any of the smaller towns, such as Pisac, Urubamba or Ollantaytambo and get local advice and information about the best trips on offer. Biking tours can also be arranged; this mountainous region offers some excellent rides and gives travelers a chance to experience the exhilaration of cliff-side roads up close. Rafting tours are also popular and are offered by numerous tour agencies.
