Dawn on the coastal highway east of Muscat and the Gulf of Oman keeps pace beside you, silver and unblinking. By the time the road thins near Tiwi, cliffs tighten, palms gather, and a narrow canyon cleaves into the limestone. This is Wadi Shab, where a footpath threads past farms and falaj channels and clear pools call you forward. The water doesn’t shout; it dares—cool, glassy, and willing to carry you deeper than you planned.

History
Wadi farming here depends on aflaj—gravity-fed irrigation channels that have watered Omani settlements for over a millennium. Hawiyat Najm’s name means “fallen star,” nodding to a meteor legend, though the sinkhole formed by limestone collapse.
Conservation
Stick to established paths to protect crops and fragile banks, and pack out all trash. Use mineral sunscreen or cover up to reduce chemical load in the pools.
