@Jurek7: No objection to the point that the public transport connection to Wildpark Langenberg isn't good (and is even bad for Swiss standards). However, as @ArizonaDocent confirmed, you can also take the train to the back gate/lower entrance, which is only a few steps away. I just brought this up to show that there is more then just one bus connection.
Still, if you ask me if I'm happy with high parking fees, the answer is simple: NO!
