The Carmel caves are the only site where both Homo Sapiens and Neanderthals have been found side by side. Despite its historical significance there is really not much to see for the casual visitor. Access is only in guided tours where you get explained about the history of the digging and can watch a film about how people lived in these caves. The entire tour takes about half an hour. Most interesting findings like bone jewelry and stone utensils are on display in the small museum of prehistory in the nearby city of Haifa (where you can also visit the WHS Bahai Gardens).
