About this water

The Vas County association calls the Gyöngyös 'the most exquisite trout water in Hungary'—summer temperatures stay below 20°C and dissolved oxygen remains high. Small, cold, oxygenated stream in Alpokalja (eastern Alpine foothills near Austrian border). Small-stream fishing: wading-led, technical, intimate. Spring to early summer and cooler periods are best. Local association area ticket plus state licence required.
