because you enter a true trek where you will know different cultures including the most native of the Sierra Nevada, the Kogui culture, you will also be surrounded by a lot of vegetation, rivers and people doing this tour before you.
Remember that you will be in a humid forest where there will be a lot of fauna and flora and you should not leave your camera or you will miss some authentic shots !!!
It is necessary to have a good physical condition since the walks are 7 to 8 hours a day
