You can reach the entrance to the flowtrails with the Hochjoch Bahn, from Schruns.
Choose from different tickets: for a single run, for the whole day, or – if you have a multi-day, season, or annual pass – only the bike transport.
Please note that bike transport is only possible with the Hochjoch Bahn.
