The mere mention of Saudi Arabia may conjure visions of bleak deserts, but you couldn't be further from the truth. Tens of millions of people visit Saudi Arabia every year, making it one of the most visited nations on the planet. Saudi Arabia offers a unique adventure to tourists, who discover so much more than harsh desert, such as stunning oases, beaches and mountain-tops and cosmopolitan culture in the big cities of Jeddah and Riyadh. Saudi Arabia is also home to the holy Muslim cities of Mecca and Medina and subsequently all Muslims make the sacred trip to the country once in their lifetime. The foundation of the country's economic growth has been its oil reserves: Saudi Arabia boasts the world's second largest petroleum reserves and is one of its largest exporters across the world, equating to almost half of the national GDP. The economy has fuelled the expansion of Riyadh's city centre, which is regarded as the centrepiece of modern-day Saudi Arabia. For a rather more wholesome Saudi experience, tourists should consider Jeddah, which is the perfect balance between ancient traditions and modern day amenities and appeal, with the nearby Red Sea a magnet for scuba diving fanatics too.
