As far as I know the nearest airport is Mannheim airport.

You may find a cheap deal to Frankfurt-Hahn airport (Ryanair) and then take a 2h-bus (Hahn Express) to Mannheim and then a train to Neustadt (see here).

or you may use the wellknown Frankfurt airport and take a train to Mannheim and then to Neustadt (see here).

If you arrive at Mannheim airport or in Frankfurt airport please let us know your schedule as soon as possible so that we try to arrange a pick up at the airport..
