Awesome and very luxurious camping adventure ! Very friendly and professional guide (Raul), incredible food (guacamole, lomo saltado...), snacks on the way, horses which carried our main bags. Sure, a little more expensive than other tours, but I don't regret it because of all the extras we got in exchange !
A lot of information about fauna and flora, cultural and historic sites during the walk. The trekking is doable even for beginners with no experience - still you should have good trekking equipment and get used to the high before !
I would recommend it if you want a great experience in Peru and cool pictures.
