Routes (by country) plan (Europe)

Europe has a lot of countries,
and thanks to EURO zone,
it's the easiest way to travel
without having to cross strict borders & customs
or doing endless PCRs..

I came up with 4 main routes
+ 1 for Iceland & Greenland
that'll help cover all of Europe.

Route 1 (13 countries) :
Britain (Ireland, Scotland, England)
​⇘ France ⇑ Belgium ⇘ Luxemburg ⇑ Switzerland ⇗
Liechtenstein ⇗ Austria ⇒ Hungary ⇑ Slovakia ⇑
Poland ⇙ Czech Republic ⇙ Germany ⇖ Netherlands 

Route 2 ( 10 + 2 countries) :
Portugal ⇗ Spain ​⇗ Andorra ⇗
Monaco ⇒ Italy + Vatican + San Marino ⇓
Malta ⇗ Greece ⇖ Albania ⇗
​North Macedonia ​⇖ Kosovo 

Route 3 ( 11 countries) :
Denmark ⇑ Norway ⇒ Sweden ⇒
Finland ⇘ Russia ⇐ Estonia ⇓
Latvia ⇓ Lithuania ⇘ Belarus ⇘
Ukraine ⇙ Moldova

Route 4 ( 7 countries ): 
Slovenia ⇘ Croatia ⇘ Bosnia &
Herzegovina ⇘ Montenegro ⇒ Serbia ⇒
Bulgaria ⇑ Romania 

And finally,
last but definitely not least -
​
Route 5 (2 countries ):
