Wadi Shab and Bimmah Sinkhole Day Trip from Muscat: Hike, Swim, and Cave Waterfall
Select participants and date
Dawn breaks over the Gulf of Oman as the coastal highway unspools toward the southeast. The sea keeps pace on your left, sapphire and insistent, while limestone bluffs rise on your right like folded pages. By late morning, the van rolls into Tiwi and the mouth of Wadi Shab, where a quick boat shuttle hums you across glassy water to the trailhead. The canyon wastes no time. Date palms shade the first steps, then the path squeezes into a corridor of pale rock, leading you upstream as the wadi nudges, teasing glimpses of turquoise in the pockets ahead.

Adventure Tips
Start early for shade and space
Hit Wadi Shab by 9 a.m. to walk in cooler temps and reach the pools before midday crowds build.
Wear grippy water shoes
Closed-toe water shoes or light approach shoes handle wet ledges and slippery rock far better than flip-flops.
Pack a dry bag
A small roll-top bag keeps your phone and snacks dry during the swim sections to the cave waterfall.
Respect flash-flood conditions
Avoid wadis after heavy rain and follow guide instructions—storms upstream can send sudden surges.
Local Insights
Wildlife
- Garra fish that gently nibble at toes in the pools
- Indian rollers and other coastal birds along the canyon and park
History
Local lore says a star fell to create Bimmah (Hawiyat Najm), but geologists point to karst collapse in the coastal limestone. Cyclone Gonu in 2007 reworked Wadi Shab’s boulder chokes, creating today’s swim-through passages.
Conservation
Pack out all trash and avoid stepping on fragile vegetation near the falaj channels. Use mineral or reef-safe sunscreen to reduce chemical load in the pools.
