Balmflue Südwand is one of the routes leading to Balmfluechöpfli.
The 9 pitch route requires 5a+, but there are variations up to 6a.
Climb time was 4 hours, need to account for 1 hour approach and 1.5 hours descent. (7 hrs~ total)
Not to be confused with Balmflue Südgrat, which is much longer, at 19 pitches and is the longest climb in Jura ( I have made that mistake before)
