Easy accessibility means visitors can marvel at ancient wonders
Saudi Arabia is more accessible than many local travellers might think, with regular flights on Cathay Pacific and the kingdom's national carrier, Saudi Arabian Airlines, linking Chek Lap Kok to Riyadh and Jeddah, the country's two major cities.
Familiar hotel brands, such as Four Seasons and Novotel, have a presence in Saudi Arabia, although they can be pricey, with some rooms costing between HK$1,500 and HK$3,200 a night.
While Saudi Arabia's wealth has ensured that its major cities are ultramodern in many respects, Jeddah and Riyadh are home to some fascinating ancient monuments.
One of the main attractions is the Masmak fortress in Riyadh, which was built in the mid-19th century, renovated in the 1980s and later converted into a museum. Its quartet of watchtowers are 18 metres high, while the walls are more than one metre thick and dotted with gun ports.
Inside the fort, a maze of rooms and courtyards seem laid out as much to improve defences against attackers as to provide privacy.
As with many public attractions in Saudi Arabia, certain times are reserved specifically for women and families to visit Masmak, so it is best to check ahead first.
Jeddah, gateway to the holy cities of Mecca and Medina, is also Saudi Arabia's commercial capital.
