Hi,
there is no such thing as interrail global pass to travel on a german bus, i read something like that somewhere on the net but i'm not sure what kind of buses i can travel on in germany??
becuse this has:
Bus 21
REX 1
From:Kirche, Lindenberg i. Allgäu
799m
To:Lindau-Insel → Determine price → interrail/eurrail pass use this time with this bus on deutschebahn app
best regrads,
Christine
