4. Nakhal Fort, Al-Batina
If you are planning to make a tour to Oman, then the Nikhal Fort is waiting for you there at Al-Batina. This is one of the most beautiful castles in the world. It has got a very balanced spectacular on the rocky surface of the Western Hajar. This fort is standing at 200 meter up at the Hajar Mountains from the 3rd to 10th century. The view of Nikhal countryside and the palm farms make it more attractive to the travellers.
