Oman cruise ship excursions include the magnificent Sultan Qaboos Grand Mosque, Muscat Royal Opera House, Mutrah Souq, National Museum, Nizwa Fort, or a visit to one of Oman’s rugged ‘wadis’ set in the stark mountain scenery. Port Sultan Qaboos in Muscat offers the most picturesque arrival of any of the Arabian ports. City tours and desert safaris can complement pre and post cruise stays.
