We did a 3days tour to the Danakil Depression. We contact  Negasi the owner of WorldSund from someone in mekele Negasi was very friendly and trustful. When we arrived in Mekele everything went right. The tour was very well organised, we enjoyed good food and enough water for the hottest place on earth. Stuff was very friendly and helpful. We enjoyed this awesome nature and had a good time in the groupe of 13 people. We would recommend this company to everybody and do it agian any time.
