Looking for literature about 4x4 tracks in Sweden

[Meir Sussman]

Hi mates ,
Was wondering if anyone hock access to information about 4x4 tracks in Northern Sweden , for instance around Sarek National Park (I read in one Guide They exist Because That Is how people That Do Not Want To Walk go inside ) . Is There a Publication , books , or literature about Any tracks ?
Want to Travel in the North this summer But go off-the - Road ...
Many thanks in advance for Valuable Info .
