One of the best tours I ever made. A 4 day trek to the Lost City in the Sierra Nevada de Santa Marta, Colombia. Meeting friendly farmers and some of the indigenous people, Wiwa and Kogi. While Wiwa are used to foreigner and also been my guide, Kogi's are very shy and it is not easy to come in touch with them. Before taking photos (except one I took with a tele lens) I always asked before taking the shot.
