The lush agricultural region of the Urubamba Valley, better known as The Sacred Valley of the Incas (El Valle Sagrado de los Incas), lies about an hour from Cusco. This 62-mile stretch of land encompasses magnificent ruins, terraced fields, and the villages of Pisac, Urubamba, Ollantytambo, and Chinchero. … more You can visit all four of these villages in a single day with a guided tour. Winding above the western half of the valley is the 27-mile-long Inca Trail, which ranks as the most significant – and popular – hiking trek in all of South America. Combine a day-trip to the valley with a two-day Inca Trail hike; tour operators around Cusco's Plaza de Armas will help map out routes. No trip would be complete without visiting Machu Picchu, the site of Peru's most remarkable Inca ruins.
