You can take the train, line S71 (or G71) from Nyugati railway station to Ivacs (buy a round-trip ticket at the vending machines in Nyugati) for 560 forints each way for each adult (so 1120 forints per person-round trip). From the stop at Ivacs, you usually have to walk to the bear farm, which is about 1.6 or 1.8 KM (about a mile). There are directing signs. Sometimes, there is an antique bus, or a sightseeing trolley which will sell you a ride from Ivacs, but that is the exception, not the rule. You can rent a bicycle in Budapest and take it on the train, for a reduced fare (235 forints each way). S71 trains run every hour, and the G71 is an additional train, following the exact same route, which runs during busy times, during the week. Take any train that shows up at Ivacs (passing from your left to your right, as you face the tracks, while standing on the platform) for your return trip. They all go to Nyugati. If you forget to buy a round trip ticket at Nyugati, you can pay cash, and buy your return ticket from Ivacs to Nyugati, from the conductor (but this is only allowed from stations without ticket windows or vending machines-- be sure to buy a ticket at Nyugati for the original trip). The train trip takes about 45 minutes, and will originate from one of the tracks numbered 1 thru 9. All train info (with timetables), in English, can be found by searching for mavcsoport.hu/en

It takes about half an hour to drive from Szentendre to the Bear Farm.

Ciao! Ho visto la tua domanda- purtroppo sei rimasto senza risposta! Provo io a risponderti in base alla ns esperienza personale. Durante l’ inverno gli orsi rimangono nelle tane, ma visto che quest’ anno non faceva troppo freddo ogni tanto si vedevano. Ma: sapevi che qui ci sono anche dei lupi? Almeno 20-30! Loro non dormino :-) e sono visibili come in nessun altro zoo! Vale la pena a visitare in ogni stagione!!!! Ciao

There is a train from Budapest Nyugati pályaudvar in a direction to Vác or Vácegres. You have to get off at Ivacs station (one station before Veresegyház) and from there you have to walk approximately 1,5 km. There are boards which show the direction to the bears. It's in the middle of nowhere so don't be afraid if you don't find civilisation on the way, you are walking on the good path :)
