On trains: the Hungary pass is valid on all MÁV-START, MÁV-HÉV and GYSEV trains, but for trains with compulsory reservation (e.g. InterCity trains) you must also book a seat reservation in addition to the Hungary pass or Hungary24!
Please note: Only the normal tickets, Hungary pass and Hungary24 can be used on any train with compulsory reservation. The County pass and County24 are not valid on these trains.
On buses: for VOLÁNBUSZ services, the Hungary pass is only valid on interurban buses. For some long-distance bus services, you will need to buy a supplementary ticket in addition to the day ticket (or regular ticket), but this is not required with the 30-day pass.
