Ad-Dakhliyah region forms the strategic interior of the Sultanate, hence, often referred to as ‘The Interior’.

The region occupies the central plateau, which descends from the foot of Western Hajar mountains in the north towards the desert in the south. Mountains in this area are distinctive with their high slopes and temperate weather; even in summer the temperature is always below 30 degrees. It is a major station on the route to other regions, bordering Muscat to the north, Ash-Sharqiyah to the east, Al-Wusta to the south and Adh-Dhahirah to the west.

Eight wilayats form Ad-Dakhliyah region, contributing 11.3% of the total population in Oman, with Nizwa being the regional centre.

Ad-Dakhliyah played an important role in Omani history, particularly in spreading Islam. In the heart of the region lies Nizwa, Pearl of Islam and Oman's early capital which was for decades a sanctuary for scholars, intellectuals and judges, and a stronghold for powerful leaders. At close proximity is Samail, home of Mazin bin Ghaduba, the first Omani to embrace Islam, and his famous mosque, the first to be established in Oman.

Ad-Dakhliyah has also been of great importance in linking the coast with the interior through crucial caravan routes and vital transit stations.

It is not surprising therefore to find that Ad-Dhakliyah boasts an array of forts, castles, watchtowers, and mosques, the most spectacular of which are the Castles of Nizwa and Bahla, Jibrin Fort and the mosques of A'Shawathinah and Al-Medhmar.

For the visitor, the combination of mountains, wadis, handicrafts and historic sites ensures a truly unique experience. Comfortable hotels and rest houses are located against a backdrop of mountains.

Ad-Dakhliyah is one of the major agricultural areas in Oman where dates, limes, mangoes and cotton are cultivated. It is also famous for its pottery industry in Bahla and rose water extraction on Al-Jabal Al-Akhdar.
