6–7 hours
Comfortable hiking 6–7 km on uneven terrain with short scrambles; confident swimmers will enjoy the cave section.
Hike and swim through Wadi Shab’s turquoise pools to a secret waterfall cave, then cool off at Bimmah Sinkhole and snap Fins’ White Beach on a streamlined day trip from Muscat. It’s Oman’s coast at its most photogenic, with just enough challenge to feel earned.
The day starts with the highway unspooling along the Gulf of Oman, cliffs leaning in as if to eavesdrop on the sea. By mid-morning you’re skimming a short boat across the mouth of Wadi Shab, where date palms fan the heat and limestone walls usher you inland. The wadi’s path wastes no time—stones clatter underfoot, the canyon narrows, and turquoise pools wink from the shadows, inviting, daring. Wind draws a cool line through the gorge while the water nudges you forward.

Temperatures rise quickly—an early pickup means easier hiking, better light in the canyon, and more time in the pools.
The approach mixes hot rock, slick boulders, and pebbly shallows; proper footwear prevents slips and cuts.
Entering the keyhole cave requires confident swimming; ask your guide for a floatation aid if unsure and never force it in high water.
A quick-dry T‑shirt and shorts over swimwear align with local customs and shield you from the sun.
Oman’s ancient aflaj irrigation systems once diverted wadi flow to terrace gardens—these waterworks are part of a UNESCO‑listed heritage that shaped settlement here.
Flash floods reshape the wadi; follow guide instructions and pack out all waste. Use mineral sunscreen and avoid touching formations inside the cave to protect fragile limestone.
Grippy soles protect feet and provide traction on slick limestone and pebbles.
The coastal heat dehydrates quickly; plan for at least 2 liters per person.
Aggressive sun exposure demands lightweight coverage for the hike and beach stops.
