Sheer promontory (120 m). It rises towards the sea west of Reynishverfi, the southernmost point of the mainland and home to rich bird life. A narrow point called Tóin just out into the sea, with an opening in it large enough to be passable by boats. Dyrhólaey is thought to have been formed during a later interglacial period in a submarine eruption resembling that which created Surtsey. Off the promontory are several rock stacks, the highest of which is Háidrangur (56 m).
