In this low-rise gem, wedged between Arabian Gulf and scenic mountains, your first impression will be of the Sultanate of Oman’s beautiful main palace. Three forts – Mutrah, Jalali and Mirani – stand guard at the entrance of Muscat. Once ashore witness lavish palaces, Zawawi Mosque, its pink marble crowned by a gilded dome, and Muttrah Souq, a jumble of crafts and clothing perfumed with spices and frankincense.
