If you want to do the Mohare Danda Trek solo, then it's possible. The trial is not difficult; however, it is one of the less-visited trails in the Himalayas. It makes the region remote and the route less crowded. The chances are high; you might not see any fellow trekkers on the way as well. In case of an emergency, you might not have anyone around you to help you. Therefore, we highly suggest you hire a guide, at least, and do not travel alone unless you are aware of the trial and have previous trekking experience in the Himalayas.
