Named after the hotel, this beach has a good view of the mountains behind.
This center offers diving trips, as well as a full range of PADI courses.
This large museum tries to illustrate the history and customs of Oman from the Stone Age to the present day. Obviously huge effort is being put in the presentation, there are many 3D printed detailed models of Omani architecture and beautifully presented artifacts. There's also a curious exhibition of (largely kitsch) presents from foreign dignitaries on the top floor.
Built as a prison in the rocky mountains in the 1580s during the Portuguese occupation, now converted into a museum devoted to Omani heritage. Unfortunately the fort is only opened to visiting dignitaries and heads of state and not open to the general public, but it's still possible to climb the steep stairs up to the top and to enjoy the view.
