The Kingdom of Saudi Arabia is a country situated in West Asia, the largest country of Arabia, by the Arabian Peninsula, bordering the Persian Gulf and the Red Sea, north of Yemen. Its extensive coastlines on the Persian Gulf and Red Sea provide great leverage on shipping through the Persian Gulf and the Suez Canal. The kingdom occupies 80% of the Arabian Peninsula. Most of the country's boundaries with the United Arab Emirates (UAE), Oman, and the Republic of Yemen are undefined, so the exact size of the country remains unknown. The Saudi government estimate is at 2,217,949 square kilometres, while other reputable estimates vary between 2,149,690 and 2,240,000 sq. kilometres. Less than 7% of the total area is suitable for cultivation, and in the early 1960s, population distribution varied greatly among the towns of the eastern and western coastal areas, the densely populated interior oases, and the vast, almost empty deserts.
The Syrian Desert, also known as the North Arabian Desert, the Jordanian steppe, or the Badiya, is a region of desert, semi-desert and steppe covering 500,000 square kilometers of the Middle East, including parts of southern Syria, eastern Jordan, northern Saudi Arabia, and western Iraq. It accounts for 85% of the land area of Jordan and 55% of Syria. To the south it borders and merges into the Arabian Desert. The land is open, rocky or gravelly desert pavement, cut with occasional wadis.

The Limes Arabicus was a desert frontier of the Roman Empire, running north from its start in the province of Arabia Petraea. It ran northeast from the Gulf of Aqaba for about 1,500 kilometers (930 mi) at its greatest extent, reaching northern Syria and forming part of the wider Roman limes system. It had several forts and watchtowers.
Qasr Harrana, sometimes Qasr al-Kharana, Harana, Qasr al-Harrana, Qasr al-Haranah, Haraneh, Khauranee, or Hraneh, is one of the best-known of the desert castles located in present-day eastern Jordan, about 60 kilometres (37 mi) east of Amman and relatively close to the border with Saudi Arabia. It is uncertain when the palace was constructed, but it likely orginates from the Umayyad Dynasty. An inscription on an upper wall dates the building to before 710 CE. A Greek or Byzantine house may have existed on the site. The purpose of the building is a subject of debate among scholars. Theories as to the qasr's purpose include a Crusader's castle, a military stronghold, agricultural outpost, and resting place for caravan travelers. The current scholarly consensus is that the building was used as for meeting between local Bedouin leaders.
Azraq is a small town in Zarqa Governorate in central-eastern Jordan, 100 kilometres (62 mi) east of Amman. The population of Azraq was 9,021 in 2004. The Muwaffaq Salti Air Base is located in Azraq.
Safaitic is a variety of the South Semitic scripts used by the Arabs in southern Syria and northern Jordan in Ḥarrah region, to carve rock inscriptions in various dialects of Old Arabic and Ancient North Arabian. The Safaitic script is a member of the Ancient North Arabian (ANA) sub-grouping of the South Semitic script family, the genetic unity of which has yet to be demonstrated.
The Ḥarrat al-Shām, also known as the Black Desert, is a region of rocky, basaltic desert straddling southern Syria and the northern Arabian Peninsula. It covers an area of some 40,000 km2 (15,000 sq mi) in the modern-day Syrian Arab Republic, Jordan, Israel and Saudi Arabia. Vegetation is characteristically open acacia shrubland with patches of juniper at higher altitudes.
The Umayyad desert castles, of which the desert castles of Jordan represent a prominent part, are fortified palaces or castles in what was the then Umayyad province of Bilad al-Sham. Most Umayyad "desert castles" are scattered over the semi-arid regions of north-eastern Jordan, with several more in Syria, Israel and the West Bank (Palestine).
The Azraq Wetland Reserve is a nature reserve located in the town of Azraq in the eastern desert of Jordan. An oasis for migratory birds, the reserve was established in 1978 and covers 12 square kilometres (4.6 sq mi). The natural springs dried up in 1992 and most migratory birds subsequently moved away from the area. Artificial springs are maintained today in order to keep the site a tourist destination.
There are at least seven nature reserves in Jordan. In 1966, the organization that would later start Jordan's nature reserves, the Royal Society for the Conservation of Nature, was founded. RSCN's first efforts involved bringing back severely endangered species. In 1973, RSCN, was given the right to issue hunting licenses, giving RSCN an upper hand in preventing extinction. The first step was the founding of Jordan's first nature reserve, Shaumari Wildlife Reserve, in 1975. The primary purpose was to create means to breed endangered species, specifically: the Arabian oryx, gazelles, ostriches and Persian onagers in their natural environment.

Wadi al-Taym, also transliterated as Wadi el-Taym, is a wadi that forms a large fertile valley in Lebanon, in the districts of Rachaya and Hasbaya on the western slopes of Mount Hermon. It adjoins the Beqaa Valley running north to south towards the Jordan Valley where it meets the northwest corner of Lake Huleh. Watered by the Hasbani river, the low hills of Wadi al-Taym are covered with rows of silver-green olive trees with the population in the area being predominantly Druze and Sunni, with a high number of Christians, mostly Greek Orthodox. Wadi al-Taym is generally considered the "birthplace of the Druze faith".
Wadi Sirhan is a wide depression in the northwestern Arabian Peninsula. It runs from the Azraq oasis in Jordan southeastward into Saudi Arabia, where most of the valley is located. It historically served as a major trade and transportation route between Syria and Arabia. From antiquity until the early 20th century, control of Wadi Sirhan was often contested by various Arab tribes. The valley is named after the Sirhan tribe which migrated there in the mid-17th century.
