4–5 hours on site (8–9 hours with transfers)
Comfortable hiking 6–7 km on uneven terrain with short scrambles; able to swim 150–200 m or use flotation.
Wadi Shab is a hike-swim hybrid where emerald pools and a waterfall cave reward a steady trek through Oman’s classic limestone canyon. Here’s how it feels—and what you need—to make the most of this iconic adventure, plus a cool-down stop at Bimmah Sinkhole.
Morning light spills over the Gulf of Oman as the first motorboat hums across the mouth of Wadi Shab, ferrying hikers to the start of a canyon that wastes no time pulling you inward. Palms lean over clear runnels, luring you upstream. Limestone walls stack higher with every bend, their seams whispering of ancient seas and sudden floods. The wadi nudges, then dares—over boulders, along falaj irrigation channels, into water that glows jade under the sun.

Aim to begin the hike by 8:00 a.m. to beat heat, crowds, and the most reflective glare on the water.
Closed-toe water shoes or amphibious sandals protect on sharp limestone and stay secure while swimming.
Use a small dry bag for your phone, snacks, and IDs; you’ll swim 150–200 m to reach the cave.
Keep small bills for the quick boat ride across the wadi mouth at the start; card payment isn’t always available.
The aflaj irrigation channels that water Tiwi’s groves are part of Oman’s centuries-old water management tradition, recognized by UNESCO. Sur nearby was once a dhow-building hub, trading across the Indian Ocean.
Pack out all trash and avoid sunscreen that washes off in freshwater pools; mineral formulas are better. Stay on rock where possible to protect fragile plants along the banks.
Essential for slick limestone, shallow wades, and the swim to the cave.
Keeps phone, snacks, and a spare layer dry during pool crossings.
Strong sun reflects off pale rock; a lightweight long-sleeve adds all-day protection.
