The Three Kings group falls into two subgroups with four main inhospitable islands and a number of smaller rocks on a submarine plateau called King Bank which rises out of extremely deep water.
Skupina Three Kings sa delí do dvoch podskupín so štyrmi hlavnými nehostinnými ostrovmi a počtom menších skalísk na podmorskej plošine nazývanej King Bank, ktorá vystupuje zo značných hĺbok.
