Machu Picchu, located 2400 meters above sea level, is without any doubts one of the most breathtaking tourist destinations. However, it is not very easily accessible, but nonetheless, worth the effort! First, quite a long trip awaits you from Cusco to Aguas Calientes.
Then, if you are fit enough you can walk and then climb the mountain with the ruins (quite steep and difficult, for about 1,5 hours) from the village of Aguas Calientes, which is basically the base for tourists visiting Machu Picchu (with the exception of the Sanctuary Lodge Hotel right beside the ruins, the only hotel at the site - 'only' about 700 USD per night).
