Traveller notes on Linz in September
Notes from nearby Berchtesgaden (121 km away)
Linz doesn't have its own notes for September yet — these are about Berchtesgaden, close enough to share the season.
Berchtesgaden's forum rates September and early October as the best hiking window — warm days, comparatively little rain, and thinner crowds right after Labor Day. Regulars are honest that the range can run from balmy to genuinely chilly and wet within the same week, since mountain weather here changes quickly — late September brings cooler nights and mornings, with a real chance of good autumn color by early October.
