Venus has some big volcanoes, but the highest one, Maat Mons, has a height of only 8 km, about that of the Big Island. For some reason, Venus has not produced any super-Hawaiis the way that Mars has, despite its lack of noticeable plate tectonics.
Maybe it's because we have found evidence(in one form or another) of H<subscript>2</subscript>O on Mars, whereas, we haven't in the case of Venus.
