Nakhal Fort & Ain Al Thowarah Thermal Springs

Rising dramatically from a massive, irregular rock outcrop against the craggy backdrop of the Western Hajar Mountains, Nakhal Fort (Husn Al Heem) in South Al Batinah is one of Oman's most visually arresting defensive citadels. Dating back to pre-Islamic times and extensively rebuilt by the Ya'aruba and Al Busaidi dynasties in the 17th and 19th centuries, the fort was engineered to conform to the contours of the natural rock mound, giving it a unique asymmetrical profile. Within its fortified crenellated ramparts are residential quarters, reception halls (majlis), weapons armories, and historic cannon emplacements. Just a few minutes' drive upstream lies Ain Al Thowarah, a natural thermal mineral spring that bubbles continuously from the rock fissures. Warm, mineral-rich water flows into a shaded falaj canal lined with date palms, where visitors relax and let wild doctor fish exfoliate their feet in the thermal waters.
