For a place called "the most beautiful End of the World" Steinberg is located rpretty central. The two airports, the one of Munich and the one of Salzburg are easily approachable by car in max. 1,5h. We do not recommend to come all the way by public transports. However, for those who want to leave their car somethimes, no problem. There is a bus stop right next to the Mesnerhof-C.
