Is it right to go on a trek alone?

Alone to travel, but never alone to trek. Not unless a given trail is a trek route. Navigating the mountains is an art. In case you lose the route, you will know how to navigate the mountains and live. Because there are high chances that no one will come to your help and access in remote mountain regions is a long shot.
There?s a lot that could go wrong. Then you won?t have anybody to help you. In high altitudes, particularly. AMS provides even the most seasoned trekkers at high altitude. You can?t move 100 meters because you?re going to be sick and weak.

Walking in a team often means to make a lot more noise than walking alone and animals are pushed alone?so there is a far lower chance of being attacked. No one can do that alone when walking. No one can express what you see with your enthusiasm. After a while, it?s sort of boring. You don?t taste as good even the lunch you prepared.
