if you are interested in old abandoned castles then yes. it was 3 years ago so i am not sure what is up now then it was opened and overgrown. I don't see who and how would they close it.
it is in really bad condition, but looks like it was beautiful when build.
if traveling from Sombor to Subotica and not in the hurry, taking the short detour to visit could be a decent option.
Before and after ! It was awesome indeed. (Saw this board a few days ago in Sombor)
