The overland Route requires that the traveler follow 10 different water courses. As it turns out, finding ones way is not as difficult as one might imagine, although to complete the route efficiently, the leadership of a guide who had completed the trip previously would have been a valuable addition to the party. It would also have been possible to provide a non-literate traveler with a simple map, indicating the direction and distance between geographic way-points. There was no doubt also trail markers were used which are now lost to history.
