Travel / how to get to Seggau Castle
>> Printable guide from Graz Airport to Seggau Castle
Short version: Buy your train ticket online (“Flughafen Graz” to “Leibnitz Bahnhof”, € 9.10), follow the black train symbols on yellow background / the covered walkway (350 meters), find platform 2 = direction Spielfeld by following the path around the construction site. Take the S1 (every 30 minutes) to Leibnitz, call a taxi: +43345275570 (Taxi Silvia – if you mention the Wegener Center or OPAC, they know where you have to go; they accept payment via card.)
Note: Credit cards aren’t accepted everywhere in Austria, especially for small expenses. We therefore recommend you get some cash/Euros. The last ATM is at the airport. ATMs in Leibnitz are approx. 40 minutes on foot from the castle.
