The United Arab Emirates is an Arabian Peninsula nation settled mainly along the Persian (Arabian) Gulf. The country is a federation of 7 emirates. Abu Dhabi, the island capital, is home to Sheikh Zayed Grand Mosque, Dubai is the site of ultramodern Burj Khalifa tower, enormous shopping centers and extravagant entertainment attractions. For most Western tourists, the UAE offers an environment that is familiar, the malls are extraordinarily modern, filled with virtually any product available in the West. The less well known side of the UAE includes remote, magnificent desert dunes on the edge of the Empty Quarter and craggy, awe-inspiring wadis in the north-east bordering Oman.
