As mentioned before, I plan to travel to former Yugoslavia countries. So I googled them all day at home. First of all, I am eager to visit these seven countries.
- Bosnia and Herzegovina（BAM）
- Croatia
- Kosovo（EUR）
- Montenegro（EUR）
- North Macedonia（MKD）
- Serbia（RSD）
- Slovenia
I narrowed down the routes from 5,040. With my three requirements below, I could pick up 16 routes. Eight of them are the reverse of the other eight.
- I can travel one-stroke
- I must enter into each country only once
- Due to a border issue, I must not cross the border straight between Kosovo and Serbia
Because three of the seven have their own currencies and cashless payment is not popular among the three, I think it’s better to visit countries with Euro currency during my early journey. Therefore, I eliminated eight routes from the candidates, and the first two countries were fixed; Slovenia and Croatia.
