Holzkirchen was the location of one of the main transmitting stations for Radio Free Europe.

There were also claims that it was so strong that locals could hear the radio programmes through their faucets [citation needed].

On the railway line called Mangfallbahn to Rosenheim, services have been operated once an hour since December 2013 by the company called 'Meridian', which is a subsidiary of Transdev Germany (before Meridian, the railway line was operated by the DB Regio AG) via Bad Aibling.

Mondays to Fridays Meridian operates nine services, which connect Rosenheim and Munich Central Station via Holzkirchen.

The following routes of the Oberbayernbus and the MVV Buses stop at the station or at the Zentraler Omnibus-Bahnhof (ZOB).
