I would love to trek the Machu Pichu but i had been warned it's pretty expensive and the trail is fairly challenging. Any recommendations?
The Machu Picchu trek is "expensive" because of the license you need to buy and because of the team accompanying you (we went in a small group, but there were more porters than participants...), but IT IS DEFINITELY WORTH IT ! The trail is challenging indeed, mostly because of the height, but you do not need any training, a normal condition is good enough. Acclimatisation to the height for 1-2 days (e.g. In cuzco) is recommended. Have fun! almost 8 years ago
