The Salkantay was very exciting but also strong.To enjoy the track you should have more than normal physics.You will see very different nature and weather.
In the first night its very cold! Bring your bed bottle with you and fill it with warm tea before sleeping! In the first day you will see a wanderful sky! In the second day wanderful nature and a good feeling when you are arrived at the top of the salkantay pass.
Register that you have to walk down very long. It will be good when you are prepared to walk down four hours. At the third day you will walk through different climazones whats exciting.
Day four you can do slip lining from hill to hill whats very exciting! After there is a four hours walk to Agua Caliente whats a little bit boring. Agua Caliente is a nice and special little town. Have fun on your trip!!!
