Ilona-völgyi Vízesés (Ilona valley waterfall) is a nice waterfall south of Parád (Mátrai Tájvédelmi körzet) in Hungary.
From Parád you have to drive south following the river Ilona. After 4 km there is e sharp bend in the road (gps 47.892380, 20.056557), with a smaller road going straight ahead. Go here straight ahead if possible: after 400 meter you have to park your car (or bike).
From here you have to walk south following the river Ilona potok upstream for appr. 900 meter.
