Arabia has intrigued travellers for centuries. Its vast swathes of desert were the swaddling clothes of infant Islam, the Arab race and of Arabic, a language considered holy by Muslims. It's also home to Islam's two holiest cities and a host of modern, thriving, oil-rich metropolises.

Following attacks on foreigners, western governments are warning against non-essential travel to Saudi Arabia. If you are staying in the country, avoid public places where Westerners are known to congregate, ensure that your hotel has a good reputation for maintaining high security precautions and stay abreast of travel advisory updates.
