My family will be spending one day hiking in around Berchtesgaden in late May/early June. We will definitely visit Almbach Gorge and probably do some hiking around the Konigsee as well. What kind of shoes will we need for the terrain on these hikes - will regular athletic shoes/sneakers be ok, or do we really need hiking shoes? Hiking shoes are heavy, so I'm hesitant to carry them around for two weeks unless we really need them (this will be our only day of true hiking, although we will do plenty of walking elsewhere).
Thank you in advance for your advice!
