Christoph Velisek, who leads the Klettersteig Courses for the ACV has informed me that the Sunshine Tours group is organising a trip to the Hochlantsch Klettersteig (difficulty level C) in Styria this coming Saturday, and that ACV members are explicitly invited. The guiding will be in english and german.
Note that there is a fee to take part in this activity of €39, as it is being run by the Sektion.
For details and registration, please see this link*.
*Sorry that the link is in german - it's quite short notice, and I don't have the time to translate. Please use the translation machine of your choice, if you cannot read german. If you have any questions, feel free to contact me by mail, and I'll try and answer them.
