Throughout the valley are fine examples of Inca architecture such as the ruins of Pisac and Ollantaytambo. Ollantaytambo was the location of the only defeat Pizarro experienced at the hands of the Incas. Throughout the valley are many small towns and villages where you have the opportunity to experience the local culture, and buy quality local products. The one place any visitor of Peru should visit is the mysterious and majestic ruins of Machu Picchu. The site is only accessible by a 4 hour train ride from Cusco.
Many agencies run day trips, but to truly experience the site, stay overnight.
There is nothing like seeing the sun break over the mountains and the fog lifting to reveal Machu Picchu in in all its glory. The ruins are well preserved, and in combination with its location deep within the Andes, absolutely breathtaking. The people of Peru are friendly. The government and the people really go out of their way to make visitors feel welcome and safe. The service is outstanding at many locations.
