We meet directly at the massive Isartor medieval city gate. Look for the guide wearing a blue name badge.
The nearest S-Bahn station is Isartor.
The tour ends at Königsplatz. From here, returning to the city centre is easy. Take the U2 U-Bahn from Königsplatz Station to Central Station (one stop - approx. one minute). Alternatively, nearby buses and trams are available, or you can simple walk to Munich Old City in less than 15 minutes.
