Hiking in Rosenheim, Germany brings together the Inn’s broad riverside paths, the old streets of Rosenheim Altstadt, and the first sharp lift of the Bavarian Alps. Walk the River Inn and Altstadt Loop via Skulpturenweg, circle Happinger See, or head south to Oberaudorf and Bad Feilnbach, where orchard country and mountain views open toward the Wendelstein foothills.
