7–8 hours
Comfortable hiking 3–4 miles on uneven, rocky terrain and capable of swimming 100–200 meters in calm freshwater.
Trace Oman’s coastal cliffs to Wadi Shab, then hike, wade, and swim into a limestone canyon where a hidden waterfall thunders in the dark. This full-day tour blends classic Sharqiyah scenery with practical, no-fuss logistics and cooling dips you’ll be thinking about long after the drive home.
The Gulf of Oman flashes silver to your left, limestone cliffs lifting like a curtain to your right, as the coast road rolls southeast from Muscat. By the time the vehicles idle beneath Tiwi’s bridge, the heat is awake and Wadi Shab is calling—rocky, bright, and full of water that refuses to sit still. A two-minute shuttle skims you across the wadi mouth, and the canyon takes over. Boulders nudge your knees. Date palms throw small islands of shade. The path is a rhythm of gravel and ledge, the wadi insisting you slow down and move deliberately.

Hit the trail by 9:00 a.m. to avoid peak heat and crowds; the canyon offers limited shade after late morning.
Hike in sturdy shoes for the rocky approach, then change to grippy water shoes for slick boulders and pool entries.
A local shuttle boat is usually required to cross the wadi mouth; carry small OMR notes for the short round-trip.
Avoid Wadi Shab during or after rain—flash floods can arrive fast and force closures.
The approach to Wadi Shab passes aflaj irrigation channels—part of Oman’s centuries-old water-sharing system that feeds date and fruit gardens in dry valleys.
Pack out all trash, skip soaps in the pools, and choose mineral-based sunscreen to reduce chemical load in freshwater.
Protects feet and provides traction on slick limestone around pools.
Keeps phone, passport, and a spare layer dry during the swim into the cave.
Offers sun protection and modest coverage when moving through villages.

Useful for the dim keyhole section and for safety if clouds reduce light in the canyon.
