7–8 hours (including 2–3 hours on trail and in the water)
Comfortable walking on uneven terrain with boulder steps and a sustained swim of 200–300 meters.
Follow Oman’s coastal road to Wadi Shab for a half-hike, half-swim adventure that ends at a secretive cave waterfall. With palm groves, emerald pools, and classic limestone scenery, this day trip from Muscat balances movement with moments worth lingering on.
Dawn loosens its grip over the Gulf of Oman as the coastal highway unwinds south from Muscat. Cliffs lean toward the sea and fishing skiffs nose the swells, urging you onward to a cut in the limestone called Wadi Shab. A quick photo stop at Bimmah Sinkhole teases the geology to come—honeycombed rock, aquamarine water—before the real adventure begins near the village of Tiwi.

Heat ramps up quickly; leaving Muscat by 7 a.m. means cooler hiking and clearer pools before crowds arrive.
Wear sturdy trail shoes for the rocky approach and pack thin water shoes for the swim section and slick boulders.
A short shuttle boat crosses the first pool at the trailhead; bring small OMR notes as card payments aren’t accepted.
Avoid the canyon if rain is forecast—flash floods can occur hours after storms. Ask your guide about current conditions.
Oman’s aflaj irrigation system, in use for over 1,500 years and inscribed by UNESCO, channels water to the date and banana groves you pass in the wadi.
Pack out all trash and avoid sunscreen-heavy swims that cloud the pools; choose mineral formulas and rinse before entering the water. Never carve or stack rocks—leave the canyon as you found it.
Grip matters on loose limestone and rounded river rock along the approach.
Protects feet and adds traction in slick pools and the cave section.
Hydration is critical in desert heat; electrolytes help stave off cramps on the return hike.
