I have studied the ERT ticket but not sure if my understanding is correct. We, 2 persons, will go like this
On Sep 21 (Sat), we will train from Salzburg > Werfen to visit Esirensewelt, and then go back Salzburg by train. After that we will take bus 150+542+543 to go Hallstat and stay the night.
For this day, I will buy ERT for the part going to Werfen. What should I buy for the bus going to Hallstat? Should I buy a bus pass and how much would it be?
Appreciate any one's help
