I cannot recommend this enough to anyone who loves nature or history. The walk along a trail 600 years old is only made better by the spectacular final destination, Machu Picchu ! You really feel as though you have left modern civilization behind and can just enjoy yourself and your surroundings. While days 2 and 3 are extraordinarily difficult, everything is made manageable by the fantastic staff who ensure that your camp is set up in advance and prepare a surprisingly good meal before you pass out in your tent at 7:30 pm. Finishing your 4 day trek at a site like Machu Picchu is almost an anti-climax after the trail but it\’s the only thing that could cap such a journey !
