A very hard 4 days trek but it was hard that made it so perfect. Excellent food, amazing view and friendly mates together. And the trip ended at MachuPichu which was trully a world class wonder¡ Strongly recommended. And I shall give my specially thanks to our poters and guide. Without their hard working we could never have finished that tour. And tips for those who want this trek: do not carry your own sleeping bags and other heavy equipments. Rent them from your agent. 4200m is not a easy job for you. Prepared well before you come. Finally, good luck and enjoy¡
