About this water

The Inn is a large, often glacially-influenced river flowing through the heart of Tyrol. Brown trout, rainbow, and grayling in the upper sections and tributaries. Summer melt colors the main stem, but the side valleys—the Zillertal, the Ötztal—hold crystal-clear water and responsive fish. Wading and bank fishing in varied terrain.
