West autobahn; exit Voralpenkreuz, direction Kirchdorf/Kr and Graz until Winsdischgarsten. Exit Roßleithen, just before Windischgarsten at a small place (storeroom and station on the left) turn right. After about 3 km in front of the Renault garage there is a sign "FERIENHOF CHRISTA" with a teddybear (logo for children friendly farms). There you turn right onto the Christa haul trail. After 2,4 km you will reach the farm at the end of the street.

From Vienna to Linz versus Selzthal. Get out at station Windischgarsten (if it´s a direct connection), otherwise at station Roßleithen.
