Dawn splits the Hajar Mountains into bands of bronze as the road leaves Muscat for the coast, trading city blocks for limestone canyons and the glitter of the Gulf of Oman. At Wadi Shab, a short boat hop ferries you across the estuary, palms fanning shade along the banks like welcoming hands. The canyon narrows. Trail rock nudges your ankles. Water murmurs beside you, never in a hurry, daring you to keep pace toward a chain of turquoise pools.
