The coast south of Muscat unfurls in pale limestone and teal water, the highway skirting fishing villages and palm groves before bending inland toward a circle of impossible blue—Bimmah Sinkhole. The limestone rim leans in like curious onlookers while the pool below flashes aquamarine, its brackish mix of groundwater and sea teasing you to dive. Resist the urge to cliff-jump; the rock hides shelves and surprises. Instead, step down, let the cool water take the road dust off, and watch swallows arc between shadow and sun. It’s a fitting warm-up to the main act: Wadi Shab.
