Mafraq governorate covers the second largest area in the kingdom, but yet the second smallest population density (after Ma'an). The climate is dry most of the year. The western region of the province is part of the fertile Houran plateaus, that extend through southern Syria, the Golan heights and northern Jordan. The eastern region is part of the barren Syrian Desert. At the eastern edge of the region is the 940m high Jebel 'Aneiza (or 'Unayzah), at the border tripoint between Jordan, Iraq and Saudi Arabia.
