Wadi Shab and Bimmah Sinkhole: Full-Day Adventure from Muscat
Select participants and date
Dawn warms the Gulf of Oman as the coastal highway slips past whitewashed villages and date palms, the sea breathing on one side while the Hajar Mountains shoulder the horizon on the other. By the time the vehicle turns inland at Tiwi, the landscape tightens into canyon country. Wadi Shab announces itself with the hush of moving water and the gleam of travertine pools—a narrow oasis daring you to trade asphalt for rock and river.

Adventure Tips
Wear grippy water shoes
Polished limestone and wet ledges are slick—closed-toe water shoes or sturdy sandals with tread improve footing.
Beat the heat with an early start
Temperatures spike by late morning; aim to be on the trail at Wadi Shab by 8–9 a.m. and carry electrolytes.
Pack modest swim layers
Quick-dry tops and longer shorts help you stay respectful around villages and families near the trail and pools.
Waterproof your tech
A small dry bag or phone pouch keeps essentials safe during swims to the grotto.

History
The Tiwi area is tied to the falaj irrigation tradition—underground and open channels that have watered farms for centuries. Nearby Sur’s dhow-building heritage fueled Indian Ocean trade well into the 20th century.
Conservation
Pack out all trash, stay off irrigation walls, and avoid cliff-jumping. Choose mineral or reef-safe sunscreen to keep the pools clear for wildlife and future visitors.
