Sinadil is a settlement in Oman, located on the northern edge of the Hajjar mountain range just south of the village of Sayh Mudayrah in Ajman, United Arab Emirates.
It is 8 km to the west of Hatta in the direction of Hadf.
Although Sinadil was originally part of Ajman, it was transferred to Oman in the 1980s.
[1] Sinadil is an old name referring to the triangular piece of land lying between Wadi Hadf and one of its distributaries.
The area is good for agriculture and the wadis are used for irrigation.
