One way to travel is to get on the bus at random and go there when you arrive. What's this tour called?

This is called "free travel"

It is characterized in that:

Just get on the bus, walk, work while walking, and even cross the border.

Sometimes, some loopholes in the national system will be exploited, such as issuing a border document visa when crossing the border and issuing a formal visa after entering the country.

Many westerners in Tibet and Nepal fall into this category.
