Leisure and Travel calls Oman “Authentic Arabia,” and there is a lot of truth in that. Featuring four UNESCO World Heritage sites, this country is diverse, rich in history, and has an abundance of natural beauty. Do not expect another UAE, which is just a short flight away and also a fascinating country in its own right. The Sultanate of Oman watchfully maintains its conservation. You won't find any skyscrapers or even high-rises, and the government even regulates the number of visitors to preserve its heritage.
