Rostaq fort is located at the foot of the impressive Western Hajar Mountains, a range of bare steep sided mountains. The fort itself does not seem as dramatically located though as the one nearby at Nakhal. Rostaq is distinguished by having a falaj flowing beneath it, but this feature is already included on the WHS list.

Rostaq is located on a loop road off the Batinah highway, and makes a delightful side trip when travelling between Muscat and Abu Dhabi.
