The participants can take the regular ISTA Shuttle bus from Vienna/Heiligenstadt (U4 underground) or Klosterneuburg center (Stadtplatz) to ISTA (VOR Bus 142, plan available here).
Lastly, you can also use the public transport services. For this option, please check the VOR website for the public transport (VOR Bus 400 to Lourdes Grotte): https://anachb.vor.at/. If the tickets are bought directly at the bus, only cash is accepted.
