Comfortable walking 6–7 km on uneven terrain with short swims or wading; non-swimmers can enjoy the lower pools.
Swim through a hidden canyon, scramble along turquoise pools, and cool off in the green waters of Bimmah Sinkhole on this private day trip from Muscat. It’s a full, rewarding dose of Oman’s canyon country—equal parts movement, geology, and quiet moments by the water.
Dawn breaks over Muscat and the highway slides along the Gulf of Oman, cliffs shouldering the road as fishing boats dapple the water below. An hour and a half later the pavement eases into the coastal village of Tiwi, where date palms shade a turquoise ribbon cutting inland. Wadi Shab doesn’t announce itself; it exhales cool air from the canyon and lets the water do the inviting. The stream nudges your ankles, urging you upstream as swifts stitch the sky overhead.

Depart Muscat early to hit the Wadi Shab trail by mid-morning when shade still lingers in the canyon.
A small cash payment is required for the short boat transfer at the trailhead to cross the wadi mouth.
Grippy water shoes or trail runners handle slick limestone and wet crossings better than sandals.
If you plan to swim to the waterfall cave, a small dry bag keeps your phone and keys safe.
The region’s aflaj irrigation channels, some over a thousand years old, still feed date gardens along the wadi. Nearby Sur remains a center of traditional dhow building, a nod to Oman’s maritime trade routes.
Pack out all trash and avoid stepping on fragile vegetation along the banks. Use mineral or reef-safe sunscreen to reduce water pollution in the pools.
Slick limestone and wet sections make good traction a must.
High heat and dry air demand steady hydration and salts.
