Yes and no! You may want to climb Kilimanjaro alone without other hikers or crowd – it is possible. But even then, you will be assisted by guides and porters. Although you will be the only trekker, you will not be alone in the truest sense as the Tanzanian Tourism Board does not permit trekking without a guide, porter and other crew members. The ratio of trekkers to support crew is 1:4 meaning that if you are the only climber, you will be assisted by 4 other members of your trekking company.
