The Zala River enters Lake Balaton west of Keszthely after winding through southwestern Hungary. It is not a showy attraction, but it helps explain why the western end of the lake feels marshier and greener than the resort towns further east.
Travellers interested in birdlife and quieter landscapes should look toward the Kis-Balaton wetlands beyond the river mouth. This is a better detour for patient nature watchers than for anyone chasing a quick scenic stop.
