8–9 hours
Comfortable hiking on uneven terrain for 3–5 km and swimming 100–200 m in calm water; able to manage heat.
Swim into a hidden waterfall, hike a canyon shaped by ancient floods, and cool off in the surreal blues of Bimmah Sinkhole—all in one day from Muscat. This tour pairs Oman’s geologic showstoppers with practical pacing and local flavor.
Dawn breaks over the Gulf of Oman as Highway 17 sweeps south from Muscat, trading city sprawl for limestone cliffs and a ribbon of turquoise coast. By the time the vehicle pulls into Tiwi, the Al Hajar Mountains lean in, sculpted by floods and time. A short boat shuttle hums across the wadi mouth, and the day’s pace shifts—water teasing the shoreline, the canyon inviting you upstream.

Aim to be on the Wadi Shab trail by mid-morning; shaded sections are limited and temperatures rise quickly.
The route mixes dry trail, slick rock, and swimming—closed-toe water shoes with solid traction prevent slips.
There’s a quick crossing at the wadi entrance; operators typically handle the fare, but bring small cash if traveling independently.
To reach the inner waterfall, you’ll pass through a narrow slot—skip it if you’re claustrophobic or waters are high.
Oman’s UNESCO-listed aflaj irrigation systems have sustained oasis farms like those in Tiwi for centuries, channeling spring water through stone-lined canals.
Canyon environments are sensitive to litter and sunscreen runoff—pack out all trash and use reef-safe products. Avoid cliff jumping and heed any flood advisories after storms.
Essential for traction on wet rock and comfort during the swim sections.
Dries fast between swims and respects local customs near villages.
High UV exposure in the canyon and at the sinkhole makes sun protection crucial.
