Unfortunately it is not very convenient to reach Plauen by plane.
From a lot of European destinations you can go to [wiki=19ed5f8ceab486afbee6b3ba5c88884d]Dresden[/wiki], [wiki=4a887b8a68acf9b04d9d027bddedb06b]Leipzig[/wiki], [wiki=baa993ff1d0f2fccb0573468522a2a4a]Nuremberg[/wiki] and take a train from there towards Plauen. But it will take at least 1.5 hours.
Plauen Hauptbahnhof (Plauen main station) is served by a lot of local trains. Also it is a stop on the InterregioExpress [wiki=baa993ff1d0f2fccb0573468522a2a4a]Nuremberg[/wiki] - [wiki=19ed5f8ceab486afbee6b3ba5c88884d]Dresden[/wiki]. Plauen also has some smaller train stations, but they are less interesting for travelers, except you are coming from [wiki=7f02affeff54a200abe9c2e21cf74a29]Gera[/wiki].
From the main station it is an 10 min walk to the city center.
Plauen can be reached without problems by car from the rest of Germany. It is well connected with the German highway system (A72).
At the moment there are just local buses around Plauen.
In the center, especially in the historic part in Old Town (Altstadt), everything is easily accessible by foot.
There is a combined system of tram (called Straßenbahn) and bus. See Plauener Strassenbahn GmbH [http://www.strassenbahn-plauen.de/].
A single ride on all tram and bus lines for 45min is 1.20€. There is no reason for a day ticket but you can purchase one for 4.60€.
The street network is very good and many roads have been refurbished recently. Except during the Christmas shopping time and at some festivals you will always find a parking space.
There are some lanes for bicycles but keep in mind that Plauen is a very hilly city.
