happen on
Find by accident
To happen on something is to find or encounter it by chance: I happened on an old photo album in the attic, We happened on a lovely café while wandering the side streets.
The phrase suggests discovery without intention—stumbling across rather than seeking out.
Also appears as happen upon.
