Hyarrostar was a wide promontory that spread out to the southeast of Númenor. Along its southern shores were wide sandy beaches, interrupted only by the mouth of the Siril, next to which stood the town of Nindamos.

Hyarrostar was most famous for its great plantations of trees that provided much of the wood used by Númenor's shipwrights.
