Karinhall was in east prussia.
Carinhall was the country residence of
Hermann Göring, built on a large hunting estate northeast of
Berlin in the
Schorfheide forest between the lakes Großdöllner See and Wuckersee in the north of
Brandenburg.
Fate
To prevent Carinhall from falling into the hands of the advancing Red Army, the compound was dynamited on 28 April 1945 at Göring's orders by a
Luftwaffe demolition squad. The art treasures were evacuated beforehand to
Berchtesgaden.

Berchtesgaden but would not have had the fuel for fly for Carinhall to Switzerland.
If I were him escaping I would have used a

Must easier to find a place to land in Switzerland and it could be painted in Swiss colours as the Swiss used the same aircraft..
also it is an easy aircraft to hide if needed for another escape.
