Main Cities
Makkah and Madinah, Islam’s two holiest cities, are located in Saudi Arabia. Makkah is the birthplace of the Prophet Muhammad and the focal point of Hajj, the Islamic pilgrimage in which almost two million Muslims from all parts of the world participate every year. Madinah is the city where Prophet Muhammad emigrated and lived. Riyadh, located in the central province, is the capital city of Saudi Arabia. It is also the high-tech center of modern Saudi Arabia and houses the headquarters of the Gulf Cooperation Council (GCC). Jeddah, located along the eastern coast of the Red Sea, is the commercial capital of Saudi Arabia, and serves as an entrance to the rest of the peninsula. Jeddah’s ports hence become the main thoroughfares for trade.
The twin cities of Jubail and Yanbu are a symbol of the government’s vision of Saudi Arabia’s future development. Jubail lies on the Arabian Gulf in the Eastern Province of the Kingdom. It is located 80 kilometers north of Dammam, and is an ancient center and caravan junction famous for pearling. It has the world’s largest petrochemical complex. Yanbu is located on the East Coast of the Red Sea about 350 kilometers north-west of Jeddah. It houses the Directorate General of the Royal Commission for Jubail & Yanbu.

Medinah is the second holiest city in Muslim world. The Prophet Muhammad (peace be upon him) and his followers migrated to this city in 622 AD.
It was in Medinah that the Islamic era began. It is the city of the Prophet. As the place where the Holy Quran was compiled, and where the Prophet's companions administered the affairs of the Muslim community, it was the seat of the first Islamic state. The Prophet (PBUH) is buried here.

Assir is a relatively fertile region in the extreme southwest (near Yemen) made up of coastal mountains. Mountain peaks rise to 3,000 meters and there is ample rainfall to support the natural vegetation and cultivation.
With juniper trees, wild olive trees, and even some larger trees, Assir is the only part of the Kingdom of Saudi Arabia to support a forest.
The Assir Region has always been densely populated. With the implementation of government irrigation schemes, the agricultural potential of the region has been increased.
Abha is located in the southwest of the Kingdom. Its position, some 7,200 feet (2,200 meters) above sea-level, gives it a relatively moderate climate. Temperatures remain within a narrower band than in many other parts of the Kingdom. It also enjoys the highest level of rainfall in all of Saudi Arabia. The natural beauty of the region and its fertility have encouraged the Saudi Arabian Government to establish a number of national parks, enabling Saudi citizens to holiday in an outstanding location of natural beauty to rival anywhere abroad.

Eastern Region
Located in the east and southeast of the Kingdom, the Eastern Region contains the Kingdom's massive petroleum reserves.

The fertile oasis-cities of Qatif and Hofuf are also located here.
Hail Region
Hail is surrounded by Al-Jouf in the north, Al-Qasim in the south, Riyadh in the east, and Tabuk in the west.
For centuries, Hail was seen as the “key to the desert” because it was the main transit point for pilgrims heading for the Holy cities of Makkah and Madinah, and for traders traveling north or south in the Arabian Peninsula.
Towards the end of the Abbasid Caliphate, when the purity of the Arab language was threatened with dilution by foreign influences, the Muslim scholars of Hail took on the responsibility for protecting and promulgating Arabic in its purest form. As a result, the city became an important center for research and knowledge.
Kuthair, Qais bin Jerwah, Al-Trimmah bin Adie, and Antarah bin Shaddad all belong to this region. The last of these was named after a poet who wrote one of the most famous of all Arab poems, “Mu'allaqat”.
The other cities of the region, Buqaa, Jubah, Hait, Al-Khitta, Rowda and Sameera, are famous for an abundance of sweet water. Wheat, dates, vegetables, and other items are cultivated here.
Jizan Region
Jizan was known in ancient times as Almikhlaf Alsulimani. It lies on the Red Sea, in the southwest of the Kingdom.
The Jizan area consists of fertile plains, forests, and mountains. The alluvial deposits brought down from the mountains by rivers and floods have created the fertile plains, which extend behind the coastal swampland. The forest region (the Alhazoun district), which is subject to flooding, consists of forests interspaced with areas of rich pasture. The mountain region is part of the Alsarawat mountain range, which makes up the jagged backbone of the Arabian Peninsula. The highest peak in Jizan is the Fifa Mountain, which rises to 11,000 feet.
The Jizan region runs along the Red Sea coast for almost 200 miles (300 km) and includes some 100 islands.

Makkah is Islam’s holiest city. Five times a day, the world's one billion Muslims, wherever they may be, turn to the Holy City of Makkah to pray.

Although Najran has a desert climate, the heavy monsoon rains that fall in the spring, combined with its underground water reserves, produce fertile agricultural land.
Originally, Najran was a small trading town known as Abul Saud. The large scale tree-planting program has created parks in Najran itself and in the surrounding villages. Najran also boasts the largest water dam in the Kingdom, the Najran Valley Dam, with a storage capacity of 85 million cubic meters (3,000 million cubic feet).

The Wadi Al-Rummah is the longest wadi (river) in the Kingdom, stretching some 370 miles (600 kms) from near Medinah to the Al-Thuwairat sands.
Buraidah has a typical desert climate with hot summers, cold winters and low humidity.
As part of the Kingdom's agricultural development program, the region of Buraidah has made an outstanding contribution to the Kingdom's wheat and poultry production. It has played a crucial role in enabling the Kingdom to become not only self-sufficient in wheat, but also a major exporter of the cereal.
Riyadh Region
The central region is considered the heartland of Saudi Arabia both physically and culturally. It is essentially a vast plateau area, but contains uplands, broad valleys, dry rivers and a number of marshes - thought to be the remnants of inland seas which existed in ancient geological times. Most of the central region is arid, with some oases in the north around Qasim.
Riyadh is the capital city of the Kingdom of Saudi Arabia and now rivals any modern city in the world with the splendor of its architecture. Broad highways sweep through the city, passing over and under each other in an impressive and still-growing network. Trees line the broad streets and avenues, giving pleasure and shade to all those who linger beneath them.
The name Riyadh is derived from the Arabic word rawdah, meaning “a place of gardens and trees.” With many wadis (a river run dry) in the vicinity, Riyadh has always been a fertile area set in the heartland of the Arabian Peninsula.
Of all the Kingdom's developmental achievements, Riyadh is perhaps the most accessible to the foreign visitor. It is served by the King Khalid International Airport, itself a marvel of design that combines traditional Arab styles with the best of modern architecture.
